Abstract: A light emitting element includes: a substrate; a first electrically conductive semiconductor layer located on the substrate; a light emitting layer located on a top surface of the first electrically conductive semiconductor layer; a second electrically conductive semiconductor layer located on a top surface of the light emitting layer; a positive electrode located on a top surface of the second electrically conductive semiconductor layer; and a negative electrode at least partially located on a side surface of the first electrically conductive semiconductor layer.

Abstract: A method for fabricating a III-V compound semiconductor solar cell includes forming a window layer made of III-V compound material over a top surface of an solar cell structure; forming a periodic array of hole textures of the window layer by using a lithography and etching process; and depositing an anti-reflection coating film to cover the window layer. A III-V compound solar cell structure is also provided to enhance the conversion efficiency of photovoltaic.
