Effect of acceptor concentration on performance of CdTe solar cell from numerical analysis

In this study, the absorber layer of Cadmium Telluride (CdTe) ultra-thin solar cell was analyzed by using the one dimensional simulator Analysis of Microelectronic and Photonic Structures (AMPS 1D) software. A novel structure of ultra-thin CdS:O/CdTe solar cell is suggested in this research that emphases on conversion efficiency. The maximum conversion efficiency of ∼ 26.24% (JSC = 27.05 mA/cm², VOC = 1.2 V, FF = 0.886) is achieved with 600 nm CdTe absorber layer at the acceptor concentration of 5 × 10¹⁹ cm⁻³. The temperature effect is also examined with an aim to realize the environmental impact on performance of the cell. Our outcomes offer innovative research guidelines for resolving persistent challenges of CdTe photovoltaics.
