摘　　要：Raindrops contain abundant renewable energy including both kinetic energy and electrostatic energy,and how to effectively harvest it becomes a hot research topic.Recently,a triboelectric nanogenerator(TENG)using liquid-solid contact electrification has been demonstrated for achieving an ultra-high instantaneous power output.However,when harvesting the energy from the dense raindrops instead of a single droplet,a more rational structure to eliminate the mutual influence of individual generation units is needed for maximize the output.In this work,a“solar panel-like”bridge array generators(BAGs)is proposed.By adopting array lower electrodes(ALE)and bridge reflux structure(BRS),BAGs could minimize the sharp drop in the peak power output for large-scale energy harvesting devices.When the area of the raindrop energy harvesting device is 15×15 cm2,the peak power output of BAGs reached 200 W/m2,which is remarkable for paving a potential industrial approach for effective harvesting raindrop energy at a large scale.
