The objective of this study was to reveal the impact aging photovoltaic ribbon welding layer materials on performance modules. We conducted thermal cycling ribbon, solar cells, and cells welded with ribbons. Using scanning electron microscopy, we observed interface morphology ribbon. results show that solder exhibited coarsening, voids increased, intermetallic compound thickened at layer. These changes can lead a decrease peeling force in layer, as well degradation After 200 cycles aging,...
In this paper, we present an approach to study the electrical and spectral degradation properties of InxGa1-xAs (x = 0.2, 0.3, 0.53) solar cell under 150 keV proton irradiation based on numerical simulation. First, structures were optimized by adjusting doping concentration base layer modifying thickness emitter layer. The structural parameter related providing higher conversion efficiency was figured out. Then, parameters such as short-circuit current density (Jsc), open-circuit voltage...
