Abstract
Photovoltaic coatings and methods of making photovoltaic coatings are provided. The photovoltaic coating contains a semiconductor layer containing semiconductor elements such as silicon particles between bottom metal-semiconductor compounds and upper metal-semiconductor compounds. The upper metal-semiconductor compounds can exist at uppermost boundary portions between semiconductor elements and not substantially over uppermost surfaces of the semiconductor elements. The method can involve forming a semiconductor layer comprising semiconductor elements such as silicon particles over a conductive layer; forming first metal-semiconductor compounds at a bottom surface of the semiconductor layer; and forming second metal-semiconductor compounds at uppermost boundary portions between the semiconductor elements.
