On the other hand, experts have some kind of reservations regarding this mechanism and the scale of effectiveness. Dr Galembeck, from the University of Campinas in Brazil has said that whenever a solid or liquid is exposed in humid environment, then the absorption capacity of water increases at the surface.

He further said that the experiments, on which he has been working and still putting in great efforts have proved that by placing metals under wet and humid environment, they can be transformed into charged ones. However, the researchers and scientists believe that the effect would be very small. Solar cell produces considerably high amount of charged particles, but still a new and innovative way of generating electricity has been found.
