Low cost, high throughput and centimeter‐scale fabrication of efficient hybrid perovskite solar cells by closed space vapor transport

Hybrid perovskite solar cell is a fast‐growing photovoltaic technology. Here, we present a method based on the closed space vapor transport deposition, which has the potential for large‐scale production due to its low cost, high throughput, and large‐area uniformity. We demonstrate CH₃NH₃PbI₃ solar cells with high power conversion efficiencies of 16.2%. Furthermore, the large area devices have high efficiency of 13.8% and good uniformity in a large substrate of 3 cm × 3 cm. (© 2016 WILEY‐VCH Verlag GmbH &Co. KGaA, Weinheim)
