据报道，钙钛矿太阳能电池（PSC）的功率转换效率（PCE）高达25.5%。因此，它们显示出巨大的商业应用潜力。因此，简化工艺流程、降低生产成本已成为科学界和工业界普遍关注的问题。在这项研究中，PSC是用最简单的器件结构（FTO/MAPbI 3/碳）制备的。通过调整p-n特性、匹配能级和增强载流子收集和传输，可以获得界面缺陷少、载流子传输良好的高质量钙钛矿薄膜。实现了12.01%的PCE，这是迄今为止针对该器件结构所报道的最佳PCE。由于消除了电荷传输层和使用了疏水材料，该器件还显示出优异的长期稳定性。该研究为降低PSC的生产成本和简化PSC的生产提供了一种新的方法。
Power conversion efficiencies (PCEs) of up to 25.5 % have been reported for perovskite solar cells (PSCs). Thus, they have shown great potential for commercial applications. Therefore, simplifying technological process and reducing production costs have been a widespread concern among scientific and industrial communities. In this study, PSCs are prepared with the simplest device architecture (FTO/MAPbI3/carbon). A high‐quality perovskite film with few interface defects and good carrier transport is obtained by tuning the p‐n properties, matching energy levels, and enhancing carrier collection and transport. A PCE of 12.01 % is achieved, which is the best reported to date for this device structure. The device also shows excellent long‐term stability, owing to the elimination of charge transport layers and the usage of hydrophobic materials. This study provides a new approach to reduce production costs and simplify production of PSCs.
