Transparent and flexible electronic devices are highly desired to meet the great demand for next-generation that lightweight, flexible, portable. conducting oxides (TCOs), such as indium-tin oxide, serve fundamental components design of transparent devices. However, indium is rare expensive. Herein, we report fabrication low-cost perovskite SrVO3 TCO films on mica substrates further demonstrate their utilization a electrode building transparent, self-powered photodetector. Superior stable optical transparency electrical conductivity retained in after bending up 105 cycles. Without an external power source, constructed all-perovskite photodetector exhibits high responsivity (42.5 mA W-1), fast response time (3.09/1.23 ms), excellent flexibility stability dozens cycles at extreme 90° angle. Our results structure-compatible transition metal-based oxides, SrVO3, electrodes have huge potential high-performance portable smart electronics.
