Abstract:
1. A method of fabricating a solar cell, the method comprising steps of: performing an oxygen-ashing treatment to a surface of a graphite substrate to form an amorphous carbon layer on the surface of the graphite substrate; forming an AlN layer on the amorphous carbon layer by a Metal Organic Chemical Vapor Deposition (MOCVD) method; forming a first n-type nitride semiconductor layer on the AlN layer; forming a mask layer with a plurality of openings on the first n-type nitride semiconductor layer; forming a plurality of second n-type nitride semiconductor layers on portions of the first n-type nitride semiconductor layer which are exposed by the plurality of openings; forming a plurality of light absorption layers on the plurality of second n-type nitride semiconductor layers; forming a plurality of p-side nitride semiconductor layers on the plurality of the light absorption layers; forming a p-side electrode electrically connected with the p-side nitride semiconductor layer; and forming an n-side electrode electrically connected with the first n-type nitride semiconductor layer.
