Abstract

CdTe/CdS solar cells of ∼10% efficiency, developed with a vacuum deposition method were irradiated with high-energy protons of different fluences. The Voc and f.f. of irradiated cells increase or decrease depending on the fluence. The normal soda lime glass substrate darkens under the irradiation; therefore low Isc is measured. Measurements suggest that CdTe solar cells are highly stable under proton flux. Flexible and lightweight solar cells were developed in a superstrate configuration on polymer substrates. 8.6 % efficiency cells with Voc∼770 mV and Isc of 20.3 mA/cm2 were achieved.
