Cloudy, rainy weather often affects the power generation of solar cells. By adding a transparent nano generator to the solar cell, a research team in China has now developed a device that can generate electricity at raindrops when raining.China Suzhou University Functional Nano and Soft Material Research Institute Sun Xuhui and Sun Bao and other researchers in the latest phase "American Chemistry Society·According to Nami Journal, this mixing device is made from a traditional silicon base solar cell and a“Friction nano generator”Composition, the latter can transform the mechanical energy of falling raindrops into electrical energy.
“Friction nano generator”It was first proposed by Professor Wang Zhonglin, Georgia Institute of Technology. Previous studies have shown that these two types of devices can be connected together with an outer wiring. In this new design, solar cells and“Friction nano generator”It is integrated through a common electrode set. The researchers believe that this design is simpler and greatly improves output efficiency.
The researchers produced the common electrode film of the apparatus using a high molecular polymer solution with high conductivity. The first author of the paper said to Xinhua News Agency, when the rain drops, the water droplets and the friction“Friction nano generator”Friction charges, the common electrode film inducts and exports charge as a charge sensing layer.
Because the friction layer is transparent, it is hardly impact on the incidence of solar light, so it will not affect the normal operation of the solar cell itself. When raining, the rainwater drop kinetic energy can also be collected, and the energy collection range is expanded. Under the large area of existing silicon-based solar cells, there is a good application prospect.
