In a cell electrons move from
WebSolar cells produce electricity when light provides the energy to move electrons out of the valence band. The electricity that is generated may then be used to power a light or tool, or it can be stored for later use by charging a battery. As of December 2014, up to 46% of the energy in sunlight could be converted into electricity using solar ... WebThe redox reaction of the two metals in the galvanic cells has electrons moving from a negative (high e- concentration) to a positive (low e- concentration area). For a battery to work, there always needs to be an electromotive force because of difference in potentials. When the two cells are equalized, there's no oomph for those electrons to move.
