This paper explores the intricate physics principles underlying the operation of photovoltaic cells, which serve as the foundation for solar power generation. By delving into the quantum mechanics of photon absorption, electron excitation, and charge separation, we elucidate the mechanisms driving the conversion of solar energy into electrical power. Through a comprehensive analysis of semiconductor physics and the photovoltaic effect, this study aims to provide a deeper understanding of how photovoltaic cells harness solar energy and contribute to sustainable energy solutions.
