[ News ] - Can Electricity Be Generated by Solar Energy on Rainy Days?

Science News Journal reported that the Chinese researchers believe that they have found the working approach of electricity generation of solar panels on rainy days. Yes, they are going to utilize the energy of rains. Well, here's what's going on.

According to the paper in international version published on the journal of Applied Chemistry showed that, the key to solve the problem was graphene. Graphene is one material, owning great conductive performance. As long as a layer of graphene rich in electron is added, a large number of electrons would flow on its surface.

When rains fall on graphene, electronics on it and cationic in the rainwater would react. Then, the energy difference would be produced. Thus, the electricity was generated. This means that even if on rainy days, electricity can be generated normally by the solar panels made of graphene.

The researchers wrote in the paper: "The highest conversion efficiency of new solar panels can reach 6.53%."Although this is not a very high efficiency, the author thinks that it’s hopeful that all-weather solar cells could solve the energy crisis.
