Influence of CdS window layer on 2-μm thick CdS/CdTe thin film solar cells
2003
Abstract Influence of the CdS window layer on the PV performances of 2-μm thick CdS/CdTe solar cells has been studied as a function of the CdS thickness, d CdS . With a reduction of d CdS from 114 to 95 nm, J SC increases due to an increase in blue response. While, at d CdS V OC and FF. The deterioration of the crystallinity of CdTe due to a decrease in the sulfur composition x of the CdTe 1− x S x mixed-crystal layer is concluded to be the most possible mechanism for the large decreases in V OC and FF.
