摘要

利用太阳能电池电容模拟器(SCAPS)软件对CdTe基太阳能电池的性能进行了研究。研究了载流子密度、CdTe吸收层厚度、工作温度、CdZnS缓冲层厚度及其载流子密度对电池性能的影响。最佳吸收层厚度为2.0µm，缓冲层厚度为0.02µm, TCO层厚度为0.02µm。对影响太阳能电池性能的各种因素进行了严格的研究;更具体地说，缓冲层和吸收层的物理参数。通过优化器件参数，在开路电压(Voc) = 1.0984 V、短路电流密度(Jsc) = 16.2023 mA/cm2、填充系数(FF) = 86.89的条件下，实现了15.46%的转换效率。

Device modeling, optimization and analysis of CdTe solar cell

The performance of the CdTe based solar cell is investigated using solar cell capacitance simulator (SCAPS) software. We have studied the influence of carrier density, thickness of the CdTe absorber layer, working temperature, CdZnS buffer layer thickness and its carrier density on the cell performance. The optimum thickness of absorber layer is found to be 2.0 µm with 0.02 µm buffer layer and 0.02 µm TCO layer. Various factors affecting the solar cell's performance has been rigorously investigated; more specifically physical parameters of buffer and absorber layer. By optimizing the device parameters we have achieved conversion efficiency of 15.46% with open circuit voltage (Voc) = 1.0984 V, short circuit current density (Jsc) = 16.2023 mA/cm2 and fill factor (FF) = 86.89.
