摘要: Abstract Energy harvest requirements for future photovoltaic devices include high efficiency, cost-effectiveness, and persistent power-generation in all weathers. To address this issue, we present here all-weather dye-sensitized solar cells that can generate electricity the daytime dark by incorporating long persistence phosphors (LPPs) into mesoscopic TiO 2 ( m -TiO ) photoanodes. When suffered simulated sunlight (air mass 1.5, 100 mW cm −2 illumination, cell having fluorescent-emitting /LPP photoanode yields a maximal photoelectric conversion efficiency of 10.08%. The unabsorbed red infrared light across layer is stored LPP phosphors, subsequently converted monochromatic fluorescence dye illumination at conditions, yielding maximized up to 26.69% as well duration lasting several hours.
