Silicon is naturally shiny, meaning it reflects light rather than absorbing it. Engineering a microscopic, textured surface or adding a chemical coating ensures that as many photons as possible enter the cell.

The engineering frontier is currently focused on and Tandem Cells . While traditional silicon cells have a theoretical efficiency limit (the Shockley-Queisser limit) of about 33%, layering different materials allows the cell to capture different parts of the light spectrum.

Solar Energy: The Physics and Engineering of Photovoltaics The shift toward renewable energy is more than a policy trend; it is a massive feat of applied physics and precision engineering. At the heart of this revolution is the solar cell, a device that converts the most abundant resource in our solar system—light—directly into electricity.
