Solar Cell
🌞 Introduction Solar cells, also known as photovoltaic (PV) cells, are at the heart of the renewable energy movement. They convert sunlight directly into electricity, offering a sustainable alternative to fossil fuels. With rapid technological advancements, solar energy is becoming more efficient, affordable, and accessible than ever before. ⚡ How Solar Cells Work Photovoltaic Effect : When sunlight hits a solar cell, photons excite electrons in the semiconductor material (usually silicon), generating an electric current. Layers of a Solar Cell : Top Layer : Anti-reflective coating to maximize light absorption. Middle Layer : Semiconductor (silicon, perovskite, or other advanced materials). Bottom Layer : Conductive base that channels electricity. 🚀 Latest Innovations in Solar Technology Perovskite Solar Cells : Lightweight, cheaper, and capable of working even on cloudy days. Tandem Cells : Combining different materials (like silicon + perovskite) to boost efficiency beyond 30...
