Abstract

A hybrid silver nanowires (AgNWs)/indium tin oxide (ITO) contact was used as a transparent back-electrode to fabricate a bifacial CdS/CdTe thin-film solar cell. The photovoltaic properties of the bifacial CdS/CdTe thin-film solar cell were investigated under front and back illumination conditions. The hybrid AgNWs/ITO back contact changed the average conversion efficiency from 0.4% (front) and 3.5% (rear) to 8.1% (front) and 0.9% (rear), respectively, improving the sum efficiency from 3.9% (ITO-only) to 9.0%. Our research demonstrates the use of a nanowire network as a transparent electrode in CdS/CdTe thin-film solar cells for bifacial or tandem applications.
