Strategies for High-Performance Large-Area Perovskite Solar Cells toward Commercialization

Perovskite solar cells (PSCs) have received a great deal of attention in the science and technology field due to their outstanding power conversion efficiency (PCE), which increased rapidly from 3.9% to 25.5% in less than a decade, comparable to single crystal silicon solar cells. In the past ten years, much progress has been made, e.g. impressive ideas and advanced technologies have been proposed to enlarge PSC efficiency and stability. However, this outstanding progress has always been referred to as small-area (<0.1 cm(2)) PSCs. Little attention has been paid to the preparation processes and their micro-mechanisms for large-area (>1 cm(2)) PSCs. Meanwhile, scaling up is an inevitable way for large-scale application of PSCs. Therefore, we firstly summarize the current achievements for high efficiency and stability large-area perovskite solar cells, including precursor composition, deposition, growth control, interface engineering, packaging technology, etc. Then we include a brief discussion and outlook for the future development of large-area PSCs in commercialization.

Automated summary

Perovskite solar cells (PSCs) have attracted much attention in the field of science and technology due to their impressive power conversion efficiency (PCE). However, little research has been conducted on the preparation processes and micro-mechanisms of large-area PSCs. Current achievements in high efficiency and stability of large-area PSCs have been summarized, but further research is needed for the commercialization of PSCs in the future.
