Simulation of Cadmium sulfide (CdS) and cadmium telluride (CdTe) based solar cell (ZnO/CdS/CdTe/NiO/Au) using Solar Cell Capacitance Simulator-1D (SCAPS-1D) has been presented in this article. Nickel oxide (NiO) and zinc oxide (ZnO) layers have been introduced as hole transport layer (HTL) and transparent conductive oxide (TCO), respectively. ZnO, CdS, and CdTe were synthesized using the facile chemical route, and their absorption coefficient was determined systematically. Later these experimentally found absorption coefficient data were used to study the effect of NiO HTL and ZnO TCO on the performance of CdS/CdTe based solar cell using SCAPS-1D. The impact of thickness, carrier concentration, defect density of the CdTe, and CdS/CdTe interface defect density on the solar cell performance was also investigated. The optimized solar cell demonstrated a maximum power conversion efficiency (PCE) of 28.04% with open circuit voltage (V_OC) of 1.09 V, short circuit current density (J_SC) of 29.09 mA/cm² and FF of 87.84% that shows huge promise in low-cost solar energy harvesting.

本文介绍了使用太阳能电池电容模拟器1D（SCAPS-1D）对基于硫化镉（CdS）和碲化镉（CdTe）的太阳能电池（ZnO / CdS / CdTe / NiO / Au）进行的模拟。已经分别引入氧化镍（NiO）和氧化锌（ZnO）层作为空穴传输层（HTL）和透明导电氧化物（TCO）。使用简便的化学路线合成了ZnO，CdS和CdTe，并系统地确定了它们的吸收系数。后来，这些通过实验发现的吸收系数数据被用于研究使用SCAPS-1D的NiO HTL和ZnO TCO对基于CdS / CdTe的太阳能电池性能的影响。还研究了厚度，载流子浓度，CdTe的缺陷密度以及CdS / CdTe界面缺陷密度对太阳能电池性能的影响。1.09 V的_OC），29.09 mA / cm ^2的短路电流密度（J _SC）和87.84％的FF显示了低成本太阳能收获的巨大希望。
