Developing novel rainwater energy harvesting beyond conventional electricity is a promising strategy to address the problems of the energy crisis and environmental pollution. In this current work, a class of self-powered PtNi and optimal PtNi-polyaniline (PANI) films are successfully developed to convert rainwater into electricity for power generation. The maximized current, voltage and power of the self-powered PtNi-PANI films are 4.95 μA per droplet, 69.85 μV per droplet and 416.54 pW per droplet, respectively, which are attributed to the charging/discharging electrical signals between the cations provided by the rainwater and the electrons offered by the films. These results indicate that the optimized signal values are highly dependent on the elevated electron concentration of films, as well as the concentration, radius and charge of ions in rainwater. This work provides fresh insights into rain energy and enriches our knowledge of how to convert renewable energy into electricity generation.
开发超越传统电力的新型雨水能量收集技术是解决能源危机和环境污染问题的一项有前景的策略。在当前这项工作中，一类自供电的铂镍（PtNi）和优化的铂镍 - 聚苯胺（PANI）薄膜被成功开发出来，用于将雨水转化为电能以进行发电。自供电的PtNi - PANI薄膜的最大电流、电压和功率分别为每滴4.95 μA、每滴69.85 μV和每滴416.54 pW，这归因于雨水中提供的阳离子与薄膜提供的电子之间的充电/放电电信号。这些结果表明，优化后的信号值高度依赖于薄膜中升高的电子浓度，以及雨水中离子的浓度、半径和电荷。这项工作为雨水能量提供了新的见解，并丰富了我们关于如何将可再生能源转化为发电的知识。
