New coating method boosts solar cell efficiency without extra heating step

Researchers have developed a faster way to coat silicon solar cells that improves their performance while cutting manufacturing costs. The bilayer coating can be applied at room temperature, eliminating an expensive heating step that currently slows down production—a potential game-changer for solar manufacturers competing on cost.
