Multiple quantum well solar cell and method of manufacturing multiple quantum well solar cell

摘要

Provided is a multi-quantum well solar cell having high photoelectric conversion efficiency at a low cost by suppressing recombination of carriers generated by light absorption in the multi-quantum well solar cell. In a multiple quantum well solar cell having a substrate, a p-type semiconductor layer, a barrier layer, a well layer, an n-type semiconductor layer and an electrode, the barrier layer and the well layer are made of a crystal having a wurtzite atomic arrangement, and A multi-quantum well type solar cell characterized in that the well layer is made of a metal oxynitride containing at least one element selected from In, Ga, and Al and a Zn element, and a piezo electric field is generated in the well layer By the battery, recombination of carriers generated by light absorption can be suppressed, and a multi-quantum well solar cell having high photoelectric conversion efficiency can be provided at low cost.
