NOVELTY - The thin-film photovoltaic cell (10) comprises a color control element for controlling color of a light transmitted through or reflected from a thin-film photovoltaic cell window, a transparent substrate or superstrata layer (12) comprising glass or polymer such as polyimide, a transparent conducting layer, a high electrical resistivity transparent layer, a semiconducting structure with n-p junctions or n-i-p junctions, and a transparent back contact structure that transmits visible light and conducts current, where the element includes selective absorbing and/or reflecting properties.    USE - The thin-film photovoltaic cell is useful as an ultra-thin film cadmium telluride cell and an ultra-thin film cadmium sulfide cell.    ADVANTAGE - The photovoltaic cell includes: the control element that controls the appearance or color of the transmitted light, controls the amount and appearance of the light reflected from the outside of the IGU and controls the amount and appearance of light reflected from the inside of the IGU thus enhancing photovoltaic cell efficiency; and an absorber layer that is sufficiently thin, uniform and pinhole free so as to be semitransparent and to have high efficiency as the solar cell.    DETAILED DESCRIPTION - The thin-film photovoltaic cell (10) comprises a color control element for controlling color of a light transmitted through or reflected from a thin-film photovoltaic cell window that is intrinsically semitransparent, generates solar electricity and transmits visible light, a transparent substrate or superstrata layer (12) comprising glass or polymer such as polyimide, a transparent conducting layer comprising transparent conducting oxide, a high electrical resistivity transparent layer, a semiconducting structure with n-p junctions or n-i-p junctions that absorb a wide range of light wavelengths and generate current and voltage, and a transparent back contact structure that transmits visible light and conducts current, where the color control element includes selective absorbing and/or reflecting properties. The color control element is a discrete structural element behind the photovoltaic cell window, a layer that is integral to a photovoltaic cell window coating and applied to the back contact structure, and another layer that is integral to the photovoltaic cell window coating and an integral part of the back contact structure. A structure of the photovoltaic cell window controls the color of light reflected from an outside of a photovoltaic cell window element. The external reflected color control element is a coating on an outside of a first glass lite and a coating between an interior surface of the first glass lite and the transparent conductor. The photovoltaic cell further comprises a reflection suppression and/or color control element that controls the amount of and color of light reflected from an interior side of the photovoltaic cell window structure such as insulating glass unit (IGU), where the interior side is a side facing an inside of a room or vehicle for the photovoltaic cell window structure. The interior reflection suppression and/or color control element is added as a separate structural element including an inner lite of the IGU or attached to the inner lite of the IGU and an integral layer to a back side of the photovoltaic cell window after a back contact/back reflector layer is formed. An INDEPENDENT CLAIM is included for a method for fabricating a thin-film photovoltaic cell.
