Perovskite solar cells (PSCs) are one of the most promising photovoltaic technologies undergoing rapid developments. PSC efficiency has reached 25.2% in only seven years, which is close to the record efficiency of silicon solar cells. In addition, the use of PSCs in tandem solar cells either in the 4-terminal or monolithic configuration, can lead to a significant increase conversion efficiency. However, the stability and the scalability are the main issues that still hinder the commercialization of the perovskite technology.

钙钛矿基太阳能电池的进展：科学和工程技术水平

钙钛矿太阳能电池（PSC）是经历快速发展的最有前途的光伏技术之一。PSC效率仅在短短7年内就达到了25.2％，接近硅太阳能电池的创纪录效率。此外，在4端或整体配置的串联太阳能电池中使用PSC可以显着提高转换效率。但是，稳定性和可扩展性仍然是阻碍钙钛矿技术商业化的主要问题。
