Finding a way to boost efficiency of CIGS solar cells
Los Angeles CA (SPX) Oct 01, 2015 - CIGS (copper-indium-gallium-selenide) solar cells are compound thin-film solar cells and the most established alternative to silicon solar cells. Solar conversion efficiencies of over 20% have recently been achieved in CIGS solar cells. One of the factors known to strongly affect the conversion efficiency is the buffer layer (see Figure 1). However, the structure of the buffer layer and it ... more
