Abstract

A hybrid solar cell and a method for manufacturing the same is disclosed, wherein the hybrid solar cell comprises a semiconductor wafer having a predetermined polarity; a first semiconductor layer on one surface of the semiconductor wafer; a second semiconductor layer on the other surface of the semiconductor wafer, wherein the second semiconductor layer is different in polarity from the first semiconductor layer; a first electrode on the first semiconductor layer; a second electrode on the second semiconductor layer; and at least one of first and second interfacial layers, wherein the first interfacial layer containing ZnO is formed between the first semiconductor layer and the first electrode, and the second interfacial layer containing ZnO is formed between the second semiconductor layer and the second electrode, wherein the hybrid solar cell is provided with the interfacial layer between the first semiconductor layer and the first electrode and/or between the second semiconductor layer and the second electrode, so that it is possible to prevent the material of the electrode from permeating into the semiconductor layer, and to collect the carriers in the semiconductor wafer and to smoothly drift the collected carriers to the electrode, thereby improving the cell efficiency.
