Other materials, such as cadmium telluride and thin-film technologies, are also utilized, though silicon remains the dominant material in the solar energy market. The advancement of new materials, such as perovskites, may revolutionize solar technology in the future, potentially leading to higher efficiency at reduced manufacturing costs.

HOW DO SOLAR CELLS WORK?
Solar cells operate on the principle of the photovoltaic effect, which involves the conversion of sunlight into electricity. When light photons strike the semiconductor material in a solar cell, they collide with electrons, providing energy that enables these electrons to flow, creating an electric current. The solar cell consists of two layers of silicon: n-type (which has extra electrons) and p-type (which has fewer electrons). When these layers are joined, an electric field is generated, prompting electrons from the n-type layer to move toward the p-type layer. This movement of electrons generates direct current (DC) electricity, which can be used to power electrical devices or stored in batteries for later use. An inverter converts the DC electricity into alternating current (AC), suitable for home and grid use, ensuring compatibility with standard electrical systems.
