Solar cells that work in rain

Now, Solar cells that can work in the rain. Image credit: In case you have read my last month’s guest post about harvesting solar energy in rust , you would be delighted to know that there has been yet another breakthrough in our attempt to harness solar energy.  For many years, solar energy has been targeted for being unavailable at night and during rains. The problem of utilizing solar energy at night can be resolved with the help of metal oxide cells as elaborated in my above post (do read it, if you have not done so already). And now researchers at the Ocean University in China have addressed the second problem and developed solar cells that can actually use rain drops to generate electricity. Published in the German journal Angewandte Chemie , the paper titled, A Solar Cell Triggered by Sun and Rain , opens a new realm of possibilities when harnessing solar energy. Coating the solar cell with a thin film of graphene allows the cell to function eve
