NOVELTY - The collector has a photo electronic device to convert solar radiation into electrical power and including a photo-sensitive surface arranged to be exposable to sunlight. An outer barrier (1032) is mounted relative to the surface such that sunlight passes through the barrier to reach the surface. The barrier comprises an outer surface arranged to be exposed to the environment and facing away from the photosensitive surface. The outer surface of the outer barrier member is convex. The barrier is shaped to retain a convex shape of the outer surface when the barrier is in a resting state.    USE - PV solar collector for reducing soiling in a PV laminate of a PV module in industrial-or commercial-type applications.    ADVANTAGE - The collector provided with an uppermost weather proof barrier is configured into a convex, upwardly bulging shape without affecting an overall solar collecting efficiency of a PV panel, and an upwardly bulged, convex shape of the outermost barrier of a PV panel can cause water droplets to flow away from the center of such a panel toward the edges, thus reducing localized areas of soiling, which can negatively impact electrical output of the PV panel. The collector includes a realization that photovoltaic cells can be bent with a curvature sufficient to provide water flow effects without affecting integrity of the photovoltaic cells, where the photovoltaic cells are bent to match the curvature of a convex uppermost layer of the PV laminate, and the cells and the uppermost layer can be bonded together using same techniques normally for flat PV laminates, thus eliminating optical aberrations result from using an upwardly convex outer layer over a flat layer of photovoltaic cells.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for making a photovoltaic (PV) solar collector.    DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a PV laminate of a PV module, where the laminate is manufactured.    Outer barrier (1032)    Support frame (2300)
