Abstract

Simulation and analysis of solar cells based on the heterojunction of zinc oxide doped with aluminum (AZO) and cadmium telluride (CdTe) with the structure (Al/AZO/CdTe/NiO/Ni) using the Simulator of the capacitance of solar cells - 1 dimension (SCAPS-1D) has been presented in this paper. AZO is used as a window layer and Nickel oxide (NiO) has been introduced as a hole transport layer (HTL). Through the software, the effect of thickness, absorber (CdTe), and window (AZO) layers carrier concentration, operating temperature, and resistances (series and shunt) have been studied. Simulation results show that the solar cell performance can be greatly improved by adjusting the layer's thickness and carrier concentration, obtaining optimal values of 10 nm and for the AZO layer, while for the CdTe layer they were 2 μm and . The optimum series and shunt resistances are in the range of 1-3 and 1800-2200 respectively. A maximum power conversion efficiency (PCE) of 14.2% is achieved with an open circuit voltage (Voc) of 0.74 V, short circuit current density (Jsc) of 26.15 and a fill factor (FF) of 72.83%, this shows AZO potential to be considered as an interesting material to replace CdS window layer.

摘要

本文介绍了基于铝掺杂氧化锌（AZO）与碲化镉（CdTe）异质结且结构为（Al/AZO/CdTe/NiO/Ni）的太阳能电池的模拟与分析，采用了一维太阳能电池电容模拟器（SCAPS-1D）。AZO用作窗口层，氧化镍（NiO）被引入作为空穴传输层（HTL）。通过该软件，研究了厚度、吸收层（CdTe）和窗口层（AZO）的载流子浓度、工作温度以及电阻（串联和并联）的影响。模拟结果表明，通过调整层的厚度和载流子浓度可大幅提高太阳能电池性能，AZO层的最佳值为10nm和[此处原文缺失具体数值]，而CdTe层的最佳值为2μm和[此处原文缺失具体数值]。最佳串联电阻和并联电阻分别在1 - 3Ω和1800 - 2200Ω范围内。在开路电压（Voc）为0.74V、短路电流密度（Jsc）为26.15mA/cm²以及填充因子（FF）为72.83%的情况下，实现了14.2%的最大功率转换效率（PCE），这表明AZO有潜力被视为替代CdS窗口层的一种有吸引力的材料。
