Organic–inorganic hybrid perovskite solar cells (PSC) are promising third‐generation solar cells. They exhibit good power conversion efficiencies and in principle they can be fabricated with lower energy consumption than many more established technologies. To improve the efficiency and long‐term stability of PSC, organic molecules are frequently used as “interlayers.” Interlayers are thin layers or monolayers of organic molecules that modify a specific interface in the solar cell. Here, the latest progress in the use of interlayers to optimize the performance of PSC is reviewed. Where appropriate interesting examples from the field of organic photovoltaics (OPV) are also presented as there are many similarities in the types of interlayers that are used in PSC and OPV. The review is organized into three parts. The first part focuses on why organic molecule interlayers improve the performance of the solar cells. The second section discusses commonly used molecular interlayers. In the last part, different approaches to make thin and uniform interlayers are discussed.

混合钙钛矿太阳能电池中的分子中间层

有机-无机混合钙钛矿太阳能电池（PSC）是有前途的第三代太阳能电池。它们具有良好的功率转换效率，并且从原理上讲，与许多现有技术相比，它们的能耗更低。为了提高PSC的效率和长期稳定性，有机分子经常被用作“中间层”。中间层是有机分子的薄层或单层，可修饰太阳能电池中的特定界面。在此，回顾了使用中间层来优化PSC性能的最新进展。由于在PSC和OPV中使用的中间层的类型有很多相似之处，因此在适当的地方还提供了来自有机光伏（OPV）领域的有趣示例。审查分为三个部分。第一部分着重介绍为什么有机分子夹层可以改善太阳能电池的性能。第二部分讨论了常用的分子中间层。在最后一部分中，讨论了制作薄而均匀的中间层的不同方法。
