The energy conversion efficiency of crystalline silicon (c-Si) solar cells is significantly limited by surface reflection losses. This paper investigates the optimization of photovoltaic performance through the application of nanostructured surface coatings. Using a theoretical framework based on the "moth-eye" biomimetic effect, we analyze how nanostructured arrays reduce the average reflectance from 35% to below 5%. The results demonstrate a significant enhancement in short-circuit current density (Jsc) and an overall relative increase in power conversion efficiency (PCE) by approximately 27%. These findings provide a scalable pathway for high-efficiency solar energy harvesting.
