But how about a solar cell that generates electricity even when the rain falls in the middle of the night? Researchers in  China's Soochow University have demonstrated such an all-weather device. What makes it possible is a triboelectric nanogenerator, which converts motion into electricity. Researchers including Zhong Lin Wang first proposed the concept of a hybrid solar cell and triboelectric nanogenerator in a paper published in 2015. Wang is a professor in the School of Materials Science and Engineering with an adjunct appointment in the School of Chemistry and Biochemistry.
