Solar panels begin as quartz sand heated to over 2,000°C to extract pure silicon. The silicon is formed into crystal ingots, sliced into ultra-thin wafers, and treated to create a PN junction. Silver conductors collect the electrical current, allowing sunlight to generate usable power. Explain It in a Beat — popular science explained through music.
