摘要：

The conversion of low-value natural environmental energy into the clean and high-value electricity provides a promising approach for solving the energy crisis and environmental pollution. Using one device to directly convert all-weather environmental energy into electricity is an ideal goal and still remains a great challenge.Here, we assembled a simple and multifunctional device with the polyoxometalate (POM)/ethyl cellulose composite film on metal substrate, which generates electricity from multiple low-value all-weather environmental energy, including sunlight, wind and raindrops. For example, the optimal Mor2Crso/ethyl cellulose composite film(Mo₇₂Cr₃₀ wt%=71.4%) exhibits remarkable output performance with the responsivity of 176.3 μA w^-1 under AM 1.5 G solar light, an average output of 4.48 μW m^-2 from wind at a speed of 10 m s^-1, and anaverage output of 0.25 μW m^-2 from raindrops at a dripping rate of 7 mL min^-1, as well as the better output power density of 6.32 μW m^-2,0.54 μW m^-2 and 8.71 μW m^-2 simultaneously driven by sunlight and wind, sunlight and raindrops, wind and raindrops, respectively. It also achieves an average output power density of17.7 μW m^-2, as well as long-term durability when it is simultaneously driven by sunlight, wind and raindrops, which exhibits 4 and 70 times than single wind and raindrops condition. For this composite film, the maximum power density is achieved at a very low resistance load of about 10 Q. The output power arises from the highefficient transport of photo-generated electrons and electrostatic charges from Mo2Crso to metal substrate.
