Configuration-centered photovoltaic applications of metal halide perovskites

Metal halide perovskites, particularly lead halide perovskites, have seen extraordinary breakthroughs in photovoltaics with power conversion efficiency swiftly surging to over 22% in the past few years, demonstrating their huge potential for rivalry with crystalline silicon solar cells in terms of production cost and performance for the future photovoltaic market. While a number of recent reviews have provided excellent overviews on the advances of metal halide perovskite materials in photovoltaics, herein we review the perovskite photovoltaics from the perspective of configuration and device design. More specifically, this review is centered on four configurations: rigid perovskite photovoltaics, flexible perovskite photovoltaics, semi-transparent perovskite photovoltaics and tandem perovskite photovoltaics. This review is going to meet the demand behind the industry and scientific community for the realistic application of perovskite photovoltaics in various requirements and circumstances.
