Abstract :
We report results from coupled optical and electrical Sentaurus TCAD models of a gallium phosphide (GaP) on silicon electron carrier selective contact (CSC) solar cell which show that Auger-limited open-circuit voltages up to 787 mV (on a 10 μm monocrystalline silicon substrate) and efficiencies up to 26.7% (on a 150 μm monocrystalline silicon substrate) may be possible for front-contacted devices which exhibit low interface recombination velocity (IRV) at the GaP/Si interface and which employ random pyramidal texturing, a detached silver reflector, rear locally diffused point contacts and a SiO2/Al2O3 rear oxide passivation stack.
