In a groundbreaking innovation, researchers at Stanford University, USA, have developed solar panels that generate electricity even at night — by harvesting heat radiatinge from the Earth into space!

These advanced panels use a special thermoelectric device that captures tiny amounts of power from the temperature difference between the cool night sky and the warmer Earth surface. Though they currently produce a small output (~50 milliwatts per square meter), it's enough to power LED lights or sensors in off-grid areas.

During the day, they function like regular solar panels — but at night, they flip the script and keep generating energy using a phenomenon called radiative cooling. This could be a game-changer for remote locations and could one day enhance our ability to harvest solar energy 24/7!

📍 Developed by Professor Shanhui Fan and team at Stanford

🔧 Still in early stages — but full of potential

🌐 Could power sensors, lights & devices in low-resource regions

A step toward continuous clean energy — even after sunset! 🌒🔋
