Title: Method for improving the efficiency of a solar cell and an improved cadmium sulfide/copper sulfide photovoltaic cell

Abstract

A CdS/Cu /SUB x/ S solar cell and method of fabricating the solar cell. The CdS layer of the solar cell is fabricated on a conductive substrate and forms an ohmic contact thereto. Thereafter, a layer of Cu /SUB x/ S is fabricated on the CdS layer and the combined structure is rinsed in an aqueous acidic rinse having a pH less than about pH3 prior to curing the device in hydrogen at an elevated temperature and fabricating a copper containing electrical contact to the Cu /SUB x/ S layer. The rinsing of the device prior to curing improves the performance of the finished solar cell.
