NOVELTY - The photovoltaic module for installation on unfinished rooftops, comprises photovoltaic cells (110-M), a frame (120-M) retaining the photovoltaic cells and exposing light-receiving surfaces of the photovoltaic cells along a first surface of the frame, a heat sink (130-M) in thermal communication with an unexposed surface of the photovoltaic cells, a thermal interface layer arranged between the heat sink and the unexposed surface to improve heat dissipation, and a conformal coating on the light-receiving surfaces transparent to visible light. The heat sink comprises a base.    USE - The photovoltaic module is useful for installation on unfinished rooftops to protect the roof structure and generate electricity.    ADVANTAGE - The photovoltaic modules have greater energy conversion efficiency as a result of the ability to dissipate the heat, are aesthetically attractive, and easy for installation over top of conventional roofs without providing primary protection of the roof.    DETAILED DESCRIPTION - The photovoltaic module for installation on unfinished rooftops, comprises photovoltaic cells (110-M), a frame (120-M) retaining the photovoltaic cells and exposing light-receiving surfaces of the photovoltaic cells along a first surface of the frame, a heat sink (130-M) in thermal communication with an unexposed surface of the photovoltaic cells, a thermal interface layer arranged between the heat sink and the unexposed surface to improve heat dissipation, and a conformal coating on the light-receiving surfaces transparent to visible light. The heat sink comprises a base positioned parallel to the unexposed surface of the cells and fins attached to the base positioned parallel to each other. The frame is adapted to mount on a finished rooftop. The base has a thickness of 0.1-0.2 inches. The fins have a height of 0.9-2 inches, a center to center spacing of 0.3-0.4 inches and a width of 0.02-0.05 inches. The center to center spacing provides a channel between the fins for cooling air to enter. The frame does not extend beyond a base of the heat sink and allows unimpeded access of ambient air to fins of the heat sink. The heat sink has a length, thickness, fin height, fin spacing and fin width to maintain the photovoltaic cell at below 150 degrees F in quiescent ambient air at 70 degrees F. A long axis of the fins is positioned parallel or perpendicular to a long axis of the heat sink, which is positioned parallel/perpendicular to a long axis of the photovoltaic module. The heat sink has a length sufficient to span greater than 3/4 the width of the photovoltaic module. The fins are discontinuous along a long axis of the base to form air escape and entry herringbone shape channels. The base is constructed of an elastomer. INDEPENDENT CLAIMS are included for:    (1) a method for fabricating a photovoltaic module;    (2) photovoltaic tiles; and    (3) a method of fabricating a photovoltaic tile.
