Blue skies and red sunsets: Reliability of performance parameters of various p-n junction photovoltaic module technologies

This research presents, discusses and compares the reliability of the performance characteristics of six different p-n junction photovoltaic module technologies under varying operating conditions. The six module technologies are: CuInSe2 (CIS), a-Si:H, a-Si:H/a-SiGe:H/a-SiGe:H (a-SiGe:H), edge-defin...

The six module technologies are: CuInSe2 (CIS), a-Si:H, a-Si:H/a-SiGe:H/a-SiGe:H (a-SiGe:H), edge-defined film-fed growth silicon (EFG-Si), multi-crystalline silicon (mc-Si) and single crystalline silicon (c-Si).
