Indoor and Outdoor Characterization of III-V/Ge Solar Cells Assembled on Glass Substrate for Concentrated Photovoltaic Applications

We propose and evaluate a new assembly process to fabricate concentrated photovoltaic (CPV) modules. We replace wire bonding, alignment, and cell interconnexions with alternative microelectronic surface mount technologies (SMT). For this purpose, solar cells are first assembled on tempered glass printed circuit boards (PCB) and then characterized indoors. This PCB is then integrated into a CPV module with an efficiency of 38.07 ℅ at CSOC measured outdoor.
