Theoretical study of ZnS/CdS bi-layer for thin-film CdTe solar cell
The performance of CdTe solar cells is strongly limited by the thickness of CdS window layer.A higher short-circuit current density might be achieved by decreasing the thickness of CdS layer as a result of reducing the absorption losses that take place in this layer. However, it is difficult to obtain uniform and pin-hole free CdS layers thinner than 50 nm. ... Read more

Theoretical analysis of ZnO and ZnO based alloys as front electrode inCdS/CdTe solar cells
ITO has unique properties to be used as front electrode in CdS/CdTe solar cells, however ITO is expensivenot abundant and consequently this type of solar cells is still relatively expensive. This work studies theusing of ZnO and ZnO based alloys such as ZnO:Sn, ZnO:Al and ZnO:In as alternative materials of ITO inorder to develop the efficiency of CdS/CdTe solar cells. ... Read more
