英语翻译
The closer an energy level is situated to the middle of the gap the higher its efficiency as a recombination center.In addition,its atomic properties are influential.They can be characterized by its capture cross sections for electrons and holes.The quality of a semiconductor material is expressed by the lifetime τ for minority carriers.Obviously,good material has a long lifetime.For solar cells,even more important is the diffusion length L,which is derived from lifetime.It is the distance an excess carrier can move by diffusion before being annihilated by recombination.Only light absorbed within a distance of about the diffusion length from the p-n junction can contribute to the electrical
output.High efficiency cells must have a diffusion length larger than the cell thickness.
