Water effect on perovskite solar cells has received growing interest in recent years. A widely accepted view is that moderate water content induces the formation of hydrate phase which enhances the recrystallization of the perovskite. However, the underlying factors which influence the formation of hydrate phase are yet to be investigated. Herein, by controlling the annealing temperature, it is demonstrated that 60 °C is the most suitable temperature for the formation of hydrated perovskite. After further annealing at 120 °C, the resulting perovskite film reveals enhanced crystallinity with a more uniform morphology, contributing to device efficiency above 20%. In addition, the water effect on different types of perovskites is studied and it is concluded that the formation of hydrated perovskite is mainly determined by the cations of the perovskite itself. The findings in this work elucidate the conditions for the formation of hydrated perovskite, contributing to the fabrication of highly efficient perovskite solar cells.

随温度变化的水对钙钛矿太阳能电池的影响
近年来，水对钙钛矿太阳能电池的影响已引起越来越多的关注。广泛接受的观点是适度的水含量会诱导水合相的形成，从而增强钙钛矿的重结晶。但是，影响水合相形成的潜在因素尚待研究。本文中，通过控制退火温度，证明60℃是最适合形成水合钙钛矿的温度。在120°C下进一步退火后，所得钙钛矿薄膜显示出增强的结晶度和更均匀的形态，有助于器件效率超过20％。此外，研究了水对不同类型钙钛矿的影响，并得出结论，水合钙钛矿的形成主要取决于钙钛矿本身的阳离子。这项工作的发现阐明了水合钙钛矿形成的条件，有助于制造高效钙钛矿太阳能电池。
