Graphene makes rainy day solar power possible
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.
As technical advances continue to reduce the cost and increase the effectiveness of solar cells, a remaining disadvantage is that they do not produce power when it is raining. Now, researchers from the Ocean University of China, Qingdao, have used graphene to produce hundreds of solar cell microvolts from simulated rainwater. Graphene is a one-atom-thick sheet of carbon with particular conductivity. In aqueous solutions, graphene binds positively charged ions to its own electrons. Because rain contains salts as well as water, when used on a solar cell, graphene attracts the positive ions in the salts, which results in two completely…
