ed with the corresponding power bandgap. Other energy into heat loss. This is known as Shockley-Queisser limit is one of the reasons to increase solar cell conversion efficiency.
MEG refers to when the energy band gap twice times when more than 1 photon absorbed by the material, will have two or more phenomena of Exciton. If it can be applied to solar cells, you can break through the limits of high conversion efficiency. If for some wavelengths of light, the internal quantum efficiency of s
