Photophysics of third-generation solar cell
Here at IIT Delhi, We are exploring the photo-physics of organic and perovskite solar cells using different optoelectronics characterization techniques.
We present a systematic investigation to determine the effects of energetic offset and disorder on different recombination losses in open circuit voltage (VOC) using time-resolved photoluminescence spectroscopy and voltage loss analysis of real fabricated devices.
At IIT-Delhi, We have a custom-built Transient photocurrent and photovoltage (TPC/TPV) measurement system to understand the charge carrier dynamics of solar cells.
Yes, we can fabricate the organic solar cell in an open environment (all the layer coating and materials are in an open environment); at IIT Delhi, we achieved more than 15% PCE with a fill factor of more than 76%. These results are comparable with the proper glove box fabrication.
