Solar Photovoltaic Division
Solar Thermal Division
Resource Assessment and Information Technology Division
Hydrogen Division
Training and HRD Division
Solar Photovoltaic Division: The SPV division is proposed to have two groups (i) R&D
group and (ii) Testing and Design group. The R&D group would have core activityon Basic
Research, Applied Research, Pre-commercial Research and the T&D group would have core
activity on Design, Testing and Certification.

SPV R&D Group
Basic Research:
“Basic Research” activity group is proposed to work on the development of
materials, devices, designs and simulation of new concepts in the device design. The key
areas would be of high efficiency silicon wafer based solar cell research, including
development of high efficiency (~23%) solar cell using innovative concepts like modified or
selective emitter, c-Si and a-Si hetero junctions with thin interfacial layers(HIT), Emitter
wrap through, front surface and back surface fields using ultra-thin wafers etc. There are
other concepts for high efficiencies such as quantum dots, up-converters or down
converters based solar cells using impurities bands. Following would be some of the areas of
basic research:




High efficiency Silicon solar cells using innovative concepts on lab scale
Development and up gradation of characterization facilities for wafers and cells
Development of reference devices and facilities for calibrations solar cells
Testing and evaluation of solar cells developed by other laboratories
Development of new materials, device structures and techniques
Applied Research:
“Applied Research” activity group is proposed to concentrate their efforts on
developmental aspects of large area solar cells, techniques, development PV modules and
systems, performance and reliability aspects of PV modules and PV systems under actual
field conditions. The group would also work on development of new modelling concepts,
innovative system designs to reduce the stresses on the modules during long term field
operation under different environments. This group would work with other testing
laboratories to gather information and collaborative research. Following are the major areas
of research for this group:

Technology validation of new technologies


Establishment of long term outdoor test beds for performance studies on PV modules
Develop PV module performance maps of the country and offer these to the users


Creation of new facilities and laboratories for system and component testing
Working closely with QCI, NABL and BIS for modification and development of SPV
standards
Pre-Commercial Research Group:
The group on “pre-commercial research” is proposed to work for the up-gradation of
the lab scale device to commercial scale, suitable for the industry to take up for the large
scale production. Dealing with the issues related with scaling up the process and
techniques. This group would work closely with the industry and tries to understand and
2
find solutions for industrial problems associated with the production and process. The major
activities are:



Study and understand scaling up process
Closely interact with the process groups of Industry
Monitoring facilities at different process steps and bench mark the performance
NISE proposes to partner with the neighbouring PV R&D group of BHEL (located in the same
campus) to develop high efficiency silicon solar cells. BHEL has already achieved > 18 % cell
efficiency on full size (6 inch) mono Si wafers. Further enhancement of cell efficiency, with a
long-term target of 23%, would be brought about using concepts of shallow emitter solar
cells coupled with back surface passivation and bi-facial solar cells, both on p-type silicon
wafers as well as novel device structures including hetero junctions using n-type silicon
wafers. In all these efforts, NISE would have a key role in cell design/ simulation, sourcing of
materials, process design and monitoring together with complete test & characterization of
solar cells and silicon materials. For cell processing, it would be necessary to procure a few
pieces of process equipment such as multi-stack diffusion furnace, pico/nano second laser
for patterning of thin films and equipment for deposition of thin films of silicon nitride/
aluminum oxide and integrate these with the existing process facility in BHEL. The cell
technologies developed in this set up would be such that these can be easily transferred to
manufacturing.
Testing & Design Group:
Solar Cell and System Testing:
The SEC has already established device characterization and performance
measurement facilities. These can be used by the research groups for their characterization
and also validate their climes made under the R&D projects. These services would be
chargeable.
The existing power electronics laboratory, lighting system testing laboratory, and
water pumping test facility will be up graded to meet the testing requirements
corresponding PV standards. These facilities will be NABL accredited to establish suitability
and acceptability of the test certificates. NISE will also setup new outdoor test beds for
different module technologies at SEC as well as other suitable sites for the data collection,
validation and mapping.

thermography (IR Camera) and Wide range Spector radiometer to take up advanced
research in the Characterization of various technology solar cells.
(iii)
Expansion of battery test facility
Storage is a very important component of SPV technology. Solar Energy Centre had
established a battery test facility in the year 2002. The facility is equipped with a life cycle
network (LCN) of 8 channels, a reserve capacity network (RCN) of 600A and a charger of 20V
200A.The facility is fully computer controlled and network adapter links the LCN and RCN
with the computer which has loaded LCN software. Different algorithms can be developed
to simulate actual field conditions for battery operations and to evaluate its performance.
This facility can also be used to develop suitable algorithms of a charger controller of a
battery, which can help in design and development of a suitable charge controller for
various applications of the batteries. The facility has also been augmented with an
environmental chamber to keep the battery at constant temperature and temperature
cycling during testing.
In the existing test facility, a battery is tested only for a very limited parameters
dealing with its physical characteristics such as, capacity and charge efficiency. To have
proper analysis of battery, the facility needs to be suitably upgraded by establishing a
chemical lab, vibrators and other related equipment. It is proposed that the existing facility
will be augmented with the inclusion of one more life cycle network of 10 circuits with
provision of automatic specific gravity measurement, and a vibrator for testing the
8
endurance, and establishing a chemical room. It is proposed that actual performance
analysis of lithium ion and vanadium redox batteries be undertaken for a long term.
(iv)

The water pumping test facility, existing power electronics laboratory, and lighting
system testing laboratory will be up graded to meet the testing requirements corresponding
PV standards. These facilities will be NABL accredited to establish suitability and
acceptability of the test certificates. NISE will also setup new outdoor test beds for different
module technologies for the data collection, validation and mapping. The process of
accreditation with NABL for these laboratories has started and would be completed during
the current year.
(v)
Up-gradation of Solar Thermal Labs
(a) Solar thermal system test lab: It is proposed to design new modern test beds for
Flat plate Collector system, Evacuated Tube Collector system, parabolic solar cookers and
solar cookers as per BIS Standards. The lab would start testing new materials and develop
low cost industrial application for process heat and boiler feed water requirements.
(b) Solar thermal R&D and Resource Assessment activity: In collaboration with
various R&D institutions and industry, a number of R&D projects on various aspects of Solar
thermal technologies such as 1 MW solar thermal power plant, Solar cooling 100kW high
efficiency absorption prototype, 5 kW absorption type air cooling, solar –biomass hybrid
cold storage for remote village application, solar Stirling Engine, Solar water distillation, etc.
have been set up and are being studied. New and innovative ideas are being tried in these
projects to develop new products. The 1 MW solar thermal power project will be taken over
by NISE from IIT Bombay from 1st January, 2015.
(vi) Establishment of IT cell, Renovation of work shop facility and Establishment of
R&D monitoring cell
It is proposed to set up an IT group in NISE. The primary objective of this group
would be to integrate all aspects of IT with the day to day functioning of the organization,
making it more effective, economic and efficient. The group shall be responsible for all IT
related support, services and technological development required to support and
strengthen the organization. This group would also see the work of Solar Resource
assessment and interact with NIWE. The work shop facility is proposed to be renovated.
R&D monitoring cell has been set up at NISE (MNRE has provided a sum of Rs. 1.00 crore for
this).
9
(Vii) Setting up of 500 kW SPV power plant &Solar collector of 60 m2 area
47.
It is proposed that the NISE campus would be made as “Smart Campus” by making it
into a ‘Net zero electricity consuming centre’ and use solar energy for lighting of building
and for cooking. In this direction the new building of NISE is a solar passive building. It is
proposed that the electrical load of the entire building would be met through in-house
power generation from solar thermal power project, SPV power projects and a large part of
cooking in the cafeteria would be done through solar steam cooking.
500 kW Photovoltaic power plant for New Building
NISE falls under a “Composite “climatic zone of the six climatic zones of India. It is at
Latitude 28025' N, Longitude 7709' E. After a detailed analysis of the radiation pattern and
weather parameters, it is observed that the optimum tilt angel will be 25 042'. It has been
found that the range of global radiation on the tilted surface vary from 50 to 950W/m2 and
the maximum percentage of annual energy fall in the 600-900 W/m2 irradiance range. The
average range of ambient temperature at NISE is vary from 25-35 °C, the range of humidity
is from 25-40 %, and the wind speed is from 1 to 3 m/s.
Technology demonstration, validation and performance comparison of different solar
technology is an important part of NISE activities. Being a newly established organisation,
and to show case the strength of solar technologies, it is proposed that a 500 kW solar PV
power project be set up in the campus of NISE with different PV technologies. Accordingly
six PV technologies are selected; the proposed capacities of PV arrays of each technology
are given below:
Mono-crystalline- 100kWp,
Multi-Crystalline100kWp,
HIT-solar cells
50kWp,
Sun power maxeon- 50kWp,
Thin films-CiGs
100 kWp
Thin films CdTe100kWp
The arrays of the proposed technology PV modules will be installed on the roof of Admin
block having an area of 500m2, exhibition block with an area 100m2, central court yard
150m2, shaded parking 170m2, and guest house approximately 500m2. Thus the total
available area for PV array installation will be 3500m2. It will be possible to accommodate
about 350kWp PV array and balance of 150kWp PV array can be installed on some portion of
ground.
10
It is also proposed all three inverter configurations centralised, string and hybrid inverters to
make it operational. In this way a customized PV technology based smart grid will be set to
handle all types of loads of Admin block, exhibition block, central court yard, guest house
and shaded parking. This serves not only a technology demonstration but also provides
highly stable and quality power supply at NISE. The above power plant of different PV
technologies is expected to generate approximately 0.7 million units of electrical power
annually which is more than the expected consumption of NISE. This amounts to a
generation of 1400 units per kWp of installed PV array capacity.
Solar steam cooking system for NISE
It is proposed to set up a Solar Cooking System at NISE. Steam and direct (roti or fry)
both type of cooking are proposed here. It is proposed to go for a hybrid and fully automatic
system for harnessing maximum solar energy. Fossil fuel (LPG) will accomplish only the
deficit of solar output during the cloudy and non-sunny days. The system will consist LPG
and Solar hybrid boiler, thermic fluid, microprocessor-based tracking mechanism, parabolic
collector, insulated oil storage container, steam cooking vessel and hot plate (for Roti).
Solar collector of 60 m2 area is requisite to cook three meal/day for 200 people. 113
Kg of steam @1500C is required for the same. The solar cooking system will reduce use of
LPG and bring in savings for the institute. The table below details the upfront investment
needed by the institute and the payback period. For better efficiency of system, a solar LPG
hybrid system is being proposed.
