Quantum Efficiency of CdS/CdTe solar cell

Abstract

In this theoretical study Quantum efficiency (QE) was calculated numerically as a function of diffusion length ( Lp) ,wavelength (λ) and absorption depth (1/α) with different values of each of depletion width (w) , absorption coefficient (α). QE is a powerful tool to characterize ( CdS/CdTe) solar cell. In this study different value of these parameters were assumed to obtain a good QE of (CdS/CdTe) solar cell, also this study shows that the value of QE is (0.96) when (α=104 cm-1 ).
