Nowadays,huge consumption of fossil fuels brings about seri-ous energy crisis and environmental problems,which urge researchers to explore novel sustainable energy sources and stor-age systems [1,2].Among them,a high packaging-efficiency sys-tem,which integrates solar cell with secondary battery together,shows great perspective in future.For example,organic-inorganic hybrid perovskites have been utilized to convert solar energy into electrical energy through the photo-charging process and store it in rechargeable devices [3].
