Abstract Organic-inorganic lead halide perovskite solar cell is on the spotlight due to its low fabrication cost and excellent optoelectronic properties. SnO2 is considered as a promising alternative for TiO2 as the electron transport layer due to its high charge mobility. Here we report on a combustion method to prepare high-performance SnO2 extraction layer. Compared to SnO2 from the conventional solution-processed method, this SnO2 layer has a faster ability to extract and transfer the photoelectron. The device based on SnO2 from combustion method obtains a power conversion efficiency of 19.12%, which has a 24.8% increase compared to the device based on SnO2 from the conventional method. Further adding Nd3+ ion to the SnO2, the PCE comes to 20.92%.

用于高效钙钛矿太阳能电池的燃烧过程沉积的 SnO2 电子传输层

摘要 有机-无机卤化铅钙钛矿太阳能电池以其低廉的制造成本和优异的光电性能而备受关注。由于其高电荷迁移率，SnO2 被认为是 TiO2 作为电子传输层的有前途的替代品。在这里，我们报告了一种制备高性能 SnO2 提取层的燃烧方法。与来自传统溶液处理方法的 SnO2 相比，该 SnO2 层具有更快的提取和转移光电子的能力。基于燃烧法SnO2的装置获得了19.12%的功率转换效率，与传统方法基于SnO2的装置相比提高了24.8%。进一步将 Nd3+ 离子添加到 SnO2 中，PCE 达到 20.92%。
