IEC seminar by Abhishek Sharan Abstract Chalcopyrites are a demonstrated material platform for realizing efficient thin-film photovoltaics, with the most well-known Cu(In,Ga)Se2 (CIGS) based solar cells exceeding 23%. Several factors, including flexibility in tuning the absorber band gap, enhanced surface treatments and electrically benign nature of common defects are responsible for the existing high performance and future promise in chalcopyrite-based photovoltaic devices. The presence a Cu-poor phase layer between the absorber and buffer layers in CIGS solar cells is known…
