Hybrid solar panels gather energy from sun and rain
We’re constantly looking for innovative ways to improve the Springwise experience, and so we’re now introducing BeeLine Reader, a new technology that helps you read more quickly and efficiently. To learn more about BeeLine Reader, an award-winning startup funded by Intel Capital, see BeeLineReader.com.
Researchers at China’s Soochow University developed an electrode that harvests energy from rain falling on solar panels. A number of innovators focus their work on ways to make solar panels smarter by making them multi-use. Another team of researchers in China used graphene to produce hundreds of solar cell microvolts from simulated rainwater. Because rain contains salts as well as water, when used on a solar cell, graphene attracts the positive ions in the salts. That results in two completely separate layers of ions - one positive and one negative. Energy generated by the impact of the rain can then…
