Abstract: Disclosed is a photovoltaic device that includes a solar cell on a light transmissive substrate in the form of an array of equal diameter optical fibers laid adjacent to each other in the transversal direction of the fibers. With such an arrangement, light harvesting at high angles is improved by 30%.

Abstract: The main object of the present invention is to provide a semitransparent photo conversion device that enhances harvesting of visible sunlight. For this purpose, a semitransparent photovoltaic cell is provided with a multilayer structure that can be used to change the color hue appearance of the cell while guaranteeing a minimum change in the light absorption capability. The photo conversion device has a direct or inverted architecture that comprises a first light transmissive electrical contact overlaying a transparent substrate, a charge blocking layer overlying the first light transmissive electrical contact and underlying the active organic photosensitive material, a second charge blocking layer overlying the active organic photosensitive material, a second light transmissive electrical contact overlying the second charge blocking layer, and a multilayer structure overlying the second light transmissive electrical contact.

Abstract: Article in the form of a slab or flag fabricated from stone agglomerate coated with thin, transparent films of TiO2 or ZnO, using dry deposition techniques, with a high level of resistance to solar degradation. The article has the form of a slab or flag fabricated from stone agglomerate coated with a thin, transparent film of TiO2 and/or ZnO with low or zero photocatalytic activity, the film being deposited by dry deposition, physical vapour deposition (PVD) or plasma enhanced chemical vapour deposition (PECVD) techniques. The article has a high level of resistance to solar degradation, which means that the resulting material is suitable for external environments.
