Que:- why do we need to keep the cells under the sunlight when they don't work well?? Is it done to regain the potential difference which got reduced to zero potential on prolonged usage of the cells??

Expert Answer
A dry cell converts chemical energy into electricity, chemical reaction produces charges that is attracted to electrodes that gives potential difference .
This chemical reaction is retarded may be when the battery is cold. Warming it up a little can increase the rate of chemical reaction.
Hence dry cell starts working for little more time. we are not charging the battery by exposing it to sunlight.
