Organic–inorganic hybrid perovskite solar cells (PSCs) have undergone an unprecedented development in the past few years and their power conversion efficiency (PCE) has reached over 23%. The conversion from light to electricity in the photovoltaic device has an intimate connection with the light absorption and charge dynamics. To further improve the PCE, it is necessary to optimize the device architecture and maximize the light absorption of the active materials, so that more photoexcited carriers can be generated and collected. The optical properties can also affect the device stability, especially for the long‐term exposure under UV light. Herein, recent progress of optical designs in PSCs toward better device performance and wider applications are summarized. The design strategies from the perspective of optical properties may further boost the development of PSCs.

钙钛矿太阳能电池的光学设计
过去几年中，有机-无机混合钙钛矿太阳能电池（PSC）经历了空前的发展，其功率转换效率（PCE）已达到23％以上。光伏装置中从光到电的转换与光吸收和电荷动力学密切相关。为了进一步改善PCE，必须优化器件结构并使活性材料的光吸收最大化，以便可以生成和收集更多的光激发载流子。光学性能也会影响器件的稳定性，尤其是在紫外线下的长期暴露。在此，总结了PSC中的光学设计在朝着更好的设备性能和更广泛的应用发展方面的最新进展。
