Development Of Enhanced Window Layers For Cigs Photovoltaic Devices, James Nicholas Alexander

Legacy Theses & Dissertations (2009 - 2024)

Photovoltaic devices are among the promising options for sustainable future energy generation. Thin film solar cells have demonstrated the ability to be a low-cost solution to clean renewable energy and are cost competitive with current silicon based photovoltaic devices. One of the most promising thin film devices right now is the Copper Indium Gallium Selenide (CIGS) solar cell with maximum reported power conversion efficiency of 22.3%. The Transparent Conducting Oxide (TCO) which is the top layer of the CIGS device also known as the window layer, is responsible for collecting the electrons generated in the CIGS device and conducting them …
