![]() They’re all doing the same job and remain identical in mass, charge, spin, and magnetic movement. ![]() Don’t let the terms confuse you though there’s actually nothing different from an electron that gets emitted from exposure to sunlight than one that flies around a circuit from a battery or direct power source. Any material that reacts to this sunlight exposure is considered a photoemissive material, and the electrons that get ejected are called photoelectrons. The photoelectric effect occurs when electrons are ejected from the surface of a solid material like metal when exposed to sunlight. This experiment paved the way for research by other Scientists like Albert Einstein, who later named this process the photoelectric effect. In 1839 French scientist Alexandre Edmond Becquerel discovered that a material like metal would send off sparks of electricity when exposed to sunlight. Solar electricity isn’t actually anything new. We just depend on that giant ball of gas in the sky (the Sun) to power our needs in this world. So how exactly do solar electricity and solar panels work? There’s no switch, sometimes not even a battery to charge. But will it be enough to release our grasp from fossil fuels? Only time will tell. This “free” source of energy is taking over our modern needs for electricity in a big way and is ultimately paving the path toward a future of sustainable energy. You might even see solar power on your way to work as you pass emergency road signs, call boxes, or speed meters. ![]() Solar electricity is all around us, from solar-powered pocket calculators to satellites and homes strapped with solar panels. 13 min read “Free” Energy: How Solar Panels & Solar Electricity Works to Power Our World ![]()
