This study used different materials as a single antireflection coating layer and found that the CdTe solar cells achieved the best efficiency with an Al2O3 single ARC layer.
Cadmium telluride (CdTe) is currently known to be one of the reliable cost-effective materials for manufacturing solar cells. In this work, different materials such as magnesium fluoride (MgF2), aluminum trioxide (Al2O3), tin oxide (SnO2), and magnesium oxide (MgO) were applied as a single antireflection coating (ARC) layer and characterized their optoelectrical properties of the resulting CdTe solar cells. A personal computer one-dimensional (PC1D) simulation study was carried out to instigate the overall performance when varying the thickness of the absorber and window layers. Simulation results confirmed that Al2O3 single ARC layer with thickness of 83 nm achieved the best efficiency of 17.81% as compared with the other ARC materials. The Al2O3 single ARC layer resulted in a short-circuit current of 2.89 A and open-circuit voltage of 0.740 V.
