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. ... إقراء المزيد

Quantitative assessment of electrical, optical and recombination losses in heterojunction CdS/CdTe solar cells
In this paper, electrical, optical and recombination losses in thin-film solar cells passed on CdS/CdTe have been evaluated. Electrical losses due to series and shunt resistances are quantitatively estimated from J-V curves. J-V characteristics are described in terms of the Sah– Noyce–Shockley theory of generation–recombination in the space-charge region of the CdS/CdTe heterostructure. Optical losses due to multiple reflections from ... إقراء المزيد
