Perovskite solar cells fabricated from organometal halide light harvesters have captured significant attention due to their tremendously low device costs as well as unprecedented rapid progress on power conversion efficiency (PCE). A certified PCE of 20.1% was achieved in late 2014 following the first study of long-term stable all-solid-state perovskite solar cell with a PCE of 9.7% in 2012, showing their promising potential towards future cost-effective and high performance solar cells. Here, notable achievements of primary device configuration involving perovskite layer, hole-transporting materials (HTMs) and electron-transporting materials (ETMs) are reviewed. Numerous strategies for enhancing photovoltaic parameters of perovskite solar cells, including morphology and crystallization control of perovskite layer, HTMs design and ETMs modifications are discussed in detail. In addition, perovskite solar cells outside of HTMs and ETMs are mentioned as well, providing guidelines for further simplification of device processing and hence cost reduction.
由有机金属卤化物光收集器制造的钙钛矿太阳能电池因其极低的器件成本以及在功率转换效率（PCE）方面前所未有的快速进展而备受关注。2012年首次研究出长期稳定的全固态钙钛矿太阳能电池，其PCE为9.7%，随后在2014年末实现了20.1%的认证PCE，显示出它们在未来具有成本效益且高性能的太阳能电池方面的巨大潜力。在此，回顾了涉及钙钛矿层、空穴传输材料（HTMs）和电子传输材料（ETMs）的主要器件结构的显著成就。详细讨论了提高钙钛矿太阳能电池光伏参数的众多策略，包括钙钛矿层的形貌和结晶控制、HTMs设计以及ETMs改性。此外，还提到了HTMs和ETMs之外的钙钛矿太阳能电池，为进一步简化器件工艺从而降低成本提供了指导。
