Paper Abstract

Space solar applications will require PV modules with large Wp/kg values with stable output characteristics under extreme insolation conditions. This report is focused on the performance of Flexible PV (FPV) modules with moderate Wp/kg ratings when exposed to sustained insolation conditions reaching a maximum of 910 Watt/m2. Three different FPV technologies have been considered, namely mono-crystalline silicon (c-Si), poly-crystalline silicon (pc-Si), and amorphous silicon (a-Si). Based on outdoor observations, the technology impact is most evident from the fill factor (FF) range demonstrated by the PV modules which is high (60 - 70%) for crystalline and polycrystalline silicon PV modules and moderate (50 - 60%) for amorphous silicon PV modules. A one diode model has been applied to all three PV modules and the theoretically calculated diode non ideality factor (n) has been compared with experimentally observed non idealities in terms of FF. Again the impact of technology is evident from 'n' value calculations which are 1.42 for c- Si, 2 for pc-Si and 3.7 for a-Si FPV modules.
