Considering such optical loss of the energy, the quantum efficiency is further classified as external and internal quantum efficiency. Solar cell is a device which converts

How do solar panels work? Solar power explained

When photons hit the solar cells they create an electric field at the junction between the layers. This electric field knocks electrons loose from the atoms in solar cells, setting them in motion. The electrons flow through the solar cell and out of the junction, generating an electrical current.

Photovoltaics
