Due to the optical properties of the electron transport layer (ETL) and hole transport layer (HTL), inverted perovskite solar cells can perform better than traditional perovskite solar cells. It is essential to compare both types to understand their efficiencies. In this article, we studied inverted perovskite solar cells with NiO/CHNHPb/ETL (ETL = MoO, TiO, ZnO) structures. Our results showed that the optimal thickness of NiO is 80 nm for all structures. The optimal perovskite thickness is 600 nm for solar cells with ZnO and MoO, and 800 nm for those with TiO. For the ETLs, the best thicknesses are 100 nm for ZnO, 80 nm for MoO, and 60 nm for TiO. We found that the efficiencies of inverted perovskite solar cells with ZnO, MoO, and TiO as ETLs, and with optimal layer thicknesses, are 30.16%, 18.69%, and 35.21%, respectively. These efficiencies are 1.5%, 5.7%, and 1.5% higher than those of traditional perovskite solar cells. Our study highlights the potential of optimizing layer thicknesses in inverted perovskite solar cells to achieve higher efficiencies than traditional structures.
由于电子传输层（ETL）和空穴传输层（HTL）的光学特性，倒置钙钛矿太阳能电池的性能优于传统钙钛矿太阳能电池。比较这两种类型的电池对于了解它们的效率至关重要。在本文中，我们研究了具有NiO/CHNHPb/ETL（ETL = MoO、TiO、ZnO）结构的倒置钙钛矿太阳能电池。我们的结果表明，对于所有结构，NiO的最佳厚度为80纳米。对于采用ZnO和MoO的太阳能电池，最佳钙钛矿厚度为600纳米，而对于采用TiO的太阳能电池，最佳钙钛矿厚度为800纳米。对于ETL，ZnO的最佳厚度为100纳米，MoO的最佳厚度为80纳米，TiO的最佳厚度为60纳米。我们发现，以ZnO、MoO和TiO作为ETL且具有最佳层厚度的倒置钙钛矿太阳能电池的效率分别为30.16%、18.69%和35.21%。这些效率分别比传统钙钛矿太阳能电池高1.5%、5.7%和1.5%。我们的研究突出了优化倒置钙钛矿太阳能电池层厚度以实现比传统结构更高效率的潜力。
