METHOD OF MAKING A SOLAR CELL

摘要

The present invention is directed to a method of making a solar cell. A substrate is formed on a surface of a base. A number of group Ill-nitride layers are formed on or above the substrate, wherein the group Ill-nitride layers are deposited using laser as excitation energy, and the band gap values of the group Ill-nitride layers progressively increase in a direction away from the substrate.
