The Method of Fabrication

It is anticipated that the XsunX Process will provide a method and structure that will form a substantially transparent solar cell. The solar cell is anticipated to be thin, flexible, and easy to make and use with conventional semiconductor processes. The solar cell is also anticipated to operate effectively as an optical filter.

In a specific embodiment, the XsunX Process includes a method of forming a solar cell. The method includes steps of providing a substrate, such as glass, plastic, Mylar and other substrates, including those with low melting points. The method also includes forming a first conductive layer overlying the substrate. The method also includes forming a first amorphous silicon layer of a first dopant type overlying the first conductive layer. A step of annealing the first amorphous silicon layer is included. The method also forms a second amorphous silicon layer of a second dopant type, and also anneals the second amorphous silicon layer. A second conductive layer is formed overlying the second amorphous silicon layer. A combination of these steps forms a transparent solar cell structure.
