HOW DOES SURFACE ROUGHNESS AFFECT SOLAR CELL PERFORMANCE?

Surface roughness significantly impacts solar cell performance via its influence on light absorption and scattering. Rougher surfaces may effectively trap light, thereby allowing photons to enter the cell more effortlessly rather than reflecting off. This added incidence of light translates to increased energy capture and conversion into usable electricity. Conversely, surfaces that are too coarse may cause undesirable scattering, which would reduce the overall efficacy of the cell. As a potential remedy, precise engineering techniques are employed to enhance the surface texture selectively to create optimum conditions for light interaction. This dual-action approach ensures that enhanced roughness benefits light absorption while minimizing scattering losses. Therefore, understanding the right balance in surface roughness is paramount for achieving improved solar cell performance, emphasizing the importance of tailored surface treatments.
