Abstract: 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. Also disclosed is a solar cell (107) that includes the electrode assembly described above, a method of forming the electrode assembly, a method of forming the solar cell, and a method of forming a solar module.

Abstract: A solar cell comprising a substrate having a front surface configured to face a light source in use, and a rear surface opposite the front surface. The front surface has a front surface morphology and the rear surface has a rear surface morphology. The front and rear surface morphologies are configured such that the front surface has a greater surface area than the rear surface. The solar cell also includes an emitter arranged on the rear surface of the substrate. Also disclosed is a method of forming a layered structure of a solar cell, which includes performing finishing processes such that a first (e.g. front) surface of a substrate has a greater surface area than a second (e.g. rear) surface. The method further includes providing a reflector layer that may be tuned to the morphology of the second surface.
