Hybrid organic-inorganic perovskite (HOIP) is a promising semiconductor for optoelectronic devices. Here, we first introduce a HOIP metasurface to enhance light absorption and boost photocurrent by more than ten times in the frequency ranging from ultraviolet to visible. Based on the HOIP metasurface, a broadband photodetector is realized. Then with a chiral perovskite metasurface, we achieve a multi-polarization-sensitive photodetector, which is sensitive to both linear and circular polarized light simultaneously. Further we develop a flexible and ultra-thin HOIP photodetector. For the application demo, the photodetector has been applied as a signal receiver for transmitting messages in broadband optical communication.
