Pioneer in silicon photovoltaics: Materials to Device………1974 onwards
Silicon Solar Cells Group at CSIR-NPL is the oldest photovoltaic group and has very rich history in silicon based photovoltaics since last four decades. We were the first to develop silicon solar cells in the country in around mid 70’s. CSIR-NPL is the first laboratory to demonstrate the complete process ‘from metallurgical grade silicon to solar grade poly silicon, fabrication of solar cells and solar penal running a water pump.

Research Activities
Currently, the group is actively involved in CSIR Energy Program ‘Technologies And Products for Solar Energy Utilization through Networks (TAPSUN)’ for the improvement of silicon solar cell efficiency to make silicon photovoltaic economically viable. The group has following prime aims for the improvement of crystalline silicon solar cell efficiency.
- Emitter engineering using selective emitter concept for silicon solar cells,
- Surface passivation schemes to reduce the surface recombination velocity,
- Surface modification schemes to reduce reflection losses,
- Metal contacts improvement;
Besides, the group is also involved in test and measurement of the photovoltaic devices. It has expertise and knowledge in fabrication, measurements, characterization, and theory to support photovoltaic (PV) research and development (R&D).
