The weather-dependence and intermittent photoelectric conversion capacity of the traditional photovoltaics call for rational design on device architecture to realize persistent power output under multiple-energy-source stimuli. Herein, we demonstrate a novel triboelectric nanogenerator/silicon (TENG/Si) tandem hybrid solar cell by stacking top silver/polydimethylsiloxane sub-cell onto bottom monocrystalline Si solar cell for simultaneously harvesting solar and rain energies. Upon systematically optimizing the device configuration and the properties of top nanogenerator, the bottom Si solar cell is used as a friction layer to regulate the charge distribution of TENG, achieving a short-circuit current of 7.59 μA, a peak open-circuit voltage of 37.19 V under the stimuli of single raindrop and a power conversion efficiency enhancement by 20% in comparison with pristine Si solar cell. Finally, 26 blue light-emitting diodes can be lighted up by one raindrop. Given the compelling advantages of enhanced power output and expanded working time, this physical proof-of-concept TENG/Si tandem hybrid solar cell provides new opportunities to collect multiple energies from nature and to promote the development of weather-independent solar cells.

传统光伏电池的天气依赖性和间歇性光电转换能力要求对器件架构进行合理设计，以在多种能源激励下实现持久的功率输出。在这里，我们通过将顶部银/聚二甲基硅氧烷子电池堆叠到底部单晶硅太阳能电池上以同时收集太阳能和雨水能量，展示了一种新型的摩擦电纳米发电机/硅（TENG / Si）串联混合太阳能电池。通过系统优化顶部纳米发电机的器件配置和性能，底部Si太阳能电池用作摩擦层来调节TENG的电荷分布，从而实现7.59μA的短路电流，37的峰值开路电压。在单一雨滴的刺激下达到19 V，与原始Si太阳能电池相比，功率转换效率提高了20％。最终，一个雨滴可以点亮26个蓝色发光二极管。鉴于提高功率输出和延长工作时间的显着优势，这种物理概念验证的TENG / Si串联混合太阳能电池提供了从自然界收集多种能量并促进与天气无关的太阳能电池发展的新机会。
