Publication number: 20240097054Abstract: An electrode assembly (100) for a solar cell. The electrode assembly comprises an insulating optically transparent film (101) comprising a plurality of perforations (103) formed therein, and a plurality of longitudinally extending, laterally spaced conductive wire portions (102) arranged side by side on a surface of the film. One or more of the perforations are formed so as to have at least a portion thereof interposed laterally between two wire portions of the plurality of wire portions. The perforations formed in the film may reduce losses that would otherwise occur due to absorption of light by the film.

Publication number: 20240063751Abstract: A frame member for a bifacial solar module. The frame member comprises a retaining portion (or e.g. a holder) configured to retain (or e.g. hold) a longitudinally extending edge of a solar module, such that the solar module, when retained (or e.g. held) by the retaining portion, extends laterally inwardly from the retaining portion along a reference plane. The frame member also includes a reflector surface disposed rearwardly and laterally inwardly of the retaining portion. The reflector surface slopes in a direction away from the reference plane such that light passing through the reference plane and onto the reflector surface is reflected by the reflector surface in a forward and laterally inward direction.Type: ApplicationFiled: December 20, 2021Publication date: February 22, 2024Applicant: REC SOLAR PTE.

Publication number: 20230318526Abstract: A slim solar module is proposed. It comprises a solar laminate comprising plural solar cells interposed between front and rear cover sheets, a frame enclosing the solar laminate and at least one reinforcement strut arranged at a rear surface of the solar laminate. A ratio between a frame surface and a frame thickness shall be between 45000 and 70000. For example, the frame may have a thickness of less than 35 mm. Specifically, the frame may have a length of 1665 mm, a width of 991 mm and a thickness of 30 mm. Due to the reduced thickness, the solar module has a reduced volume being beneficial during transport to a destination location. However, the thickness has been optimized to, with the reinforcement struts, still providing for sufficient mechanical stability for the solar module.Type: ApplicationFiled: June 1, 2023Publication date: October 5, 2023Applicant: REC SOLAR PTE.
