摘要
Halide perovskites show excellent optoelectronic properties for solar cell application.Notably,perovskite crystalline structures have been widely re-ported to deliver superior ferroelectric properties.As a result,the integration of the ferroelectric process with the photon‐to‐electron energy conversion process becomes feasible to generate interesting photo‐physical properties and further boost the device performance of perovskite solar cells(PSCs),which have started to attract more and more attention in recent years.Here,we have reviewed the recent progress in PSCs with ferroelectricity(FE‐PSCs),by classifying them into three regimes according to the degree of phase segre-gation,for example,the layer‐structured ferroelectric/halide perovskite com-posite,micro phase‐separated ferroelectric/halide perovskite composite,and the intrinsic ferroelectric halide perovskite composite.The different composite structures enable a large range of interesting optoelectronic properties and the specific structure significantly enhances the device performance of PSCs.The most prominent contribution of ferroelectricity is that it can provide an extra electrical field to drive charge generation,transport,and collection.Further,key challenges and opportunities of the integration of ferroelectricity with photo-voltaics are discussed.We hope our work can draw intensive attention in this field to accelerate the establishment of the basic theories in ferroelectricity and the commercialization of PSCs.
