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.
