Experimental and theoretical studies of (CdS)1-x (ZnS)x thin-films for second generation CdS/CdTe solar cells
The current work focused on studying the optical and structural properties of (CdS)1-x (ZnS)x thin films fabricated by thermal vacuum evaporation approach. The evaporation was implemented at room temperature from bulk samples synthesis by sintering approach. The energy gap, index of refraction, extinction coefficient and absorption coefficient were estimated from the experiment and employed in our theoretical model to estimate ... Read more

Theoretical Studies of Thin-Film Solar Cells based on CdTe with different Window-Layers
The effect of using different types of window layer on the performance of thin-film solar cell based on CdTe was studied. Here, we investigated Cadmium Sulphide (CdS), Zinc Selenide (ZnSe) and Zinc Sulphide (ZnS) as window layer candidates. The calculations of short-circuit current density, internal quantum efficacy, external quantum efficient and the solar cell efficacy were achieved based on the ... Read more

Improvement of the performance of thin-film CdS/PbS solar cells using low-cost ZnO-based alloys as front electrode
All thin film solar cells require the use of transparent conductive electrodes such as indium tin oxide (ITO) due to its unique combination of transparency, high conductivity, durability, and favourable surface properties. Indium, however, is a rare and expensive metal; proposed large-area installations of photovoltaic (PV) cells will add further strain to global indium supply. Transparent conductive materials that are ... Read more
