Title (EN) PHOTOVOLTAIC (PV) ENHANCEMENT FILMS FOR ENHANCING OPTICAL PATH LENGTHS AND METHODS OF MANUFACTURING PV ENHANCEMENT FILMS
(FR) FILMS D'AMÉLIORATION PHOTOVOLTAÏQUES (PV) POUR AMÉLIORER LES LONGUEURS DE TRAJETS OPTIQUES ET PROCÉDÉS DE FABRICATION DES FILMS D'AMÉLIORATION PV
Abstract:
(EN) A solar energy conversion assembly (100) for efficiently capturing solar energy (104) by providing additional chances to absorb reflected sunlight (106). The assembly (100) includes one or more solar cells (410) that each include a light-receiving surface (414). A fraction of light incident (522) upon the light-receiving surface (414) is reflected. The assembly (400) includes a photovoltaic (PV) enhancement film (420) of transparent material such as plastic positioned to cover at least a portion of the light-receiving surface (414). The PV enhancement film (420) includes a substrate (426) positioned proximate to or abutting the light-receiving surface (414). The film (420) includes a plurality of total internal reflection (TIR) elements (428) on the substrate (426) opposite the light-receiving surface (414). The TIR elements (428) transmit initially received or incident light to the light-receiving surface of the solar cell without significant focusing and then use TIR to trap a substantial portion (532, 554) of the reflected light (524, 528) to provide additional chances for absorption such that typically lost light may be converted to electricity.
(FR) La présente invention concerne un ensemble de conversion d'énergie solaire (100) conçu pour capturer de façon efficace l'énergie solaire (104) en fournissant des occasions supplémentaires d'absorber la lumière solaire réfléchie (106). L'ensemble (100) comprend une ou plusieurs cellules solaires (410) comprenant chacune une surface de réception de lumière (414). Une fraction de lumière incidente (522) est réfléchie sur la surface de réception de lumière (414). L'ensemble (400) comprend un film d'amélioration photovoltaïque (PV) (420) en matériau transparent, tel que du plastique, positionné de façon à couvrir au moins une partie de la surface de réception de lumière (414). Le film d'amélioration PV (420) comprend un substrat (426) placé à proximité de la surface de réception de lumière (414) ou en butée avec celle-ci. Le film (420) comprend une pluralité d'éléments de réflexion interne totale (TIR)(428) sur le substrat (426), à l'opposé de la surface de réception de lumière (414). Les éléments TIR (428) transmettent la lumière initialement reçue ou incidente à la surface de réception de lumière de la cellule solaire sans focalisation significative et ensuite utilisent la TIR pour piéger une partie substantielle (532, 554) de la lumière réfléchie (524, 528) afin de fournir des occasions supplémentaires d'absorption de sorte que la lumière généralement perdue puisse être convertie en électricité.
