Abstract
A cell has a substrate, a first microstructure and an active layer. The first microstructure is formed on the substrate and has therein a first material with a concentration gradient toward one side of the substrate to provide a first built-in electric field. The active layer is mounted on the first microstructure so as to reduce recombination of electrons and holes in the cell.
