Abstract
A solar cell and a method of manufacturing the same are provided. The method comprises: forming a first electrode layer on a substrate; forming a semiconductor film of first conduction type on the first electrode layer; forming a germanium film on the semiconductor film of first conduction type, and topologizing the germanium film by using a functionalization element so as to obtain a semiconductor film of second conduction type having characteristics of topological insulator, the semiconductor film of first conduction type mating with the semiconductor film of second conduction type having characteristics of topological insulator to form a p-n junction; and forming a second electrode layer on the semiconductor film of second conduction type. The solar cell manufactured according this method has higher electric energy conversion efficiency.
