How do solar panels turn sunlight into electricity?

Have you ever looked at the sleek, silent solar panels on a rooftop and wondered how they perform the magic of turning pure sunlight into electricity? This episode pulls back the curtain on one of the cleanest and most important technologies of our time. We trace the journey of a single particle of light from the sun's core across 93 million miles of space to a silicon cell on Earth. You'll learn about the 19th-century discovery that started it all, the 1950s breakthrough at Bell Labs, and how the Space Race was critical to developing the technology. We break down the complex science of semiconductors, P-N junctions, and the photovoltaic effect into simple, easy-to-understand analogies. We'll also explore the complete system, from the crucial role of the inverter to the solutions like batteries and the grid that answer the age-old question: "What ...
