Hybrid organic-inorganic perovskite solar cells (PSCs) are the novel fourth-generation solar cells, with impressive progress in the last few years. MAPbI is a cost-effective material used as an absorber layer in PSCs. Due to the different diffusion length of carriers, the electron transporting material (ETM) plays a vital role in PSCs' performance. ZnO ETM is a promising candidate for low-cost and high-efficiency photovoltaic technology. In this work, the normal n-i-p planar heterojunction structure has been simulated using SCAPS-1D. The influence of various parameters such as the defect density, the thickness of the MAPbI layer, the temperature on fill factor, the open-circuit voltage, the short circuit current density, and the power conversion efficiency are investigated and discussed in detail. We found that a 21.42% efficiency can be obtained under a thickness of around 0.5 μm, and a total defect of 10 cm at ambient temperature. These simulation results will help fabricate low-cost, high-efficiency, and low-temperature PSCs.
有机-无机杂化钙钛矿太阳能电池（PSCs）是新型的第四代太阳能电池，在过去几年中取得了令人瞩目的进展。MAPbI是一种用作PSCs吸收层的具有成本效益的材料。由于载流子的扩散长度不同，电子传输材料（ETM）在PSCs的性能中起着至关重要的作用。ZnO ETM是低成本、高效率光伏技术的一个有前途的候选材料。在这项工作中，使用SCAPS-1D对常规的n-i-p平面异质结结构进行了模拟。详细研究和讨论了各种参数，如缺陷密度、MAPbI层厚度、温度对填充因子、开路电压、短路电流密度和功率转换效率的影响。我们发现，在室温下，当厚度约为0.5μm且总缺陷为10cm时，可以获得21.42%的效率。这些模拟结果将有助于制造低成本、高效率和低温的PSCs。
