Effects of residual copper selenide on CuInGaSe2 solar cells

Large grain and copper-poor CuInGaSe 2 (CIGS) film is preferred to fabricate high efficiency solar cells. However, the degradation caused by excess copper selenide (Cu 2-x Se) is still a problem. This study investigates the formation and behavior of excess CuxSe and further compares the cell perform...
