Porcelain stoneware tilesare getting a prominent role on the market offering excellent solution either for interiors or for exteriors construction for flooring and coverings. This ceramic material meets the basic requirements to be compatible with different semiconductor deposition technique. Based on these consideration we investigated the possibility of using porcelain stoneware tiles as solar cells substrates for built-integrated photovoltaic applications. The compatibility of the commercial tiles with the solar cell fabrication process was successful proved and a conversion efficiency of more than 4% has been obtained on a small area devices as a preliminary result
