How a PV Cell Works
When the photons strike a solar cell, some are absorbed while others are reflected.When the material absorbs sufficient photon energy, electrons within the solar cell material dislodge from their atoms. The electrons migrate to the front surface of the solar cell, which is manufactured to be more receptive to the free electrons.When many electrons, each …
