Prof. Sun Baoquan from the Institute of Functional Nano and Soft Matter, Soochow University, and Prof. Sun Xuhui's research group have published papers on ACS Nano. Hybrid solar panels based on Triboelectric Nanogenerator (TENG) technology can be developed on sunny days. In rainy weather, electricity can be generated and stored, and electricity can be collected in rainy weather using frictional nano-generation efficiency generated by raindrops on the surface of the material.
Self-powered sensing systems based on frictional nanogenerators can use external environmental mechanical vibrations to generate electrical energy to provide power. In this case, researchers collected the friction generated by the falling motion of raindrops on the surface of solar cell materials, hybrid solar energy. Dimethicone polymer was used for the top layer of the panel, while poly(3,4-ethylenedioxythiophene)-polystyrene sulfonate (PEDOT/PSS) was used for the next layer. The top layer was dropped in the raindrops. Activated, the polymer is in contact with the next layer, and the PEDOT/PSS film acts as a common electrode for both, allowing the triboelectric nanogenerator to supply power directly to the solar cell, allowing the latter to collect electrical energy from the former. On sunny days, , The materials are transparent to ensure that the photovoltaic cells can normally collect solar energy.
