 Self-powered monoelectrodes made from graphene composite films to harvest rain energyYuanyuan Zhao, Zhibin Pang, Jialong Duan, Yanyan Duan, Zhengbo Jiao and Qunwei Tang Energy, 2018, vol. 158, issue C, 555-563 Abstract: Development of self-powered monoelectrodes for clean energy harvest is a promising solution to meet the growing energy demands for modern electronic device applications. To address this issue, a category of self-powered monoelectrodes are made from cost-effective graphene composite films to harvest rain energy. Periodic current and voltage signals are recorded under rain stimulation to evaluate their rain-to-electricity efficiency. The mechanism behind rain energy harvest arises from charging/discharging cycles of electric π-electron (graphene)|cation (rain) double-layer pseudocapacitances at graphene film/raindrop interface. The maximized current of 2.15 μA/raindrop, voltage of 129.83 μV/raindrop and power of 295.48 pW/raindrop are yielded in the optimized conversion devices. The present work may provide new insights on harvesting waste energies in rain-enriched regions by designing electron-enriched monoelectrodes.
