Future Solar Panels Will Generate Energy From Raindrops

11.04.2016 | Science News Journal | www.sciencenewsjournal.com

A new solar cell prototype developed by a team of scientists in Qingdao, China may change the way we use solar panels in the not so distant future.

Solar panel technology has changed the way many people bring energy into their homes, but this type of technology has always posed one concern: panels cannot output optimal power without ideal weather conditions. When you have rainy days or a lot of cloud cover, there is only so much energy that panels can store for later use.

Solar cells generate power in rain

Chinese scientists are now able to create electricity with the assistance of raindrops. This is thanks to a thin layer of graphene they use to coat their solar cells during testing. Graphene is known for its conductivity, among many other benefits. All it takes is a mere one-atom thick graphene layer for an excessive amount of electrons to move as they wish across the surface.

These new solar cells can be stimulated by incident light on sunny days and raindrops when it’s raining, yielding an optimal energy conversion efficiency of 6.53 %.
