@xrayworld: How Sunlight Becomes Electrical Energy Solar panels use photovoltaic cells to convert sunlight into electricity. Many modern solar cells use silicon as the semiconductor. Sunlight arrives as photons carrying energy. The silicon absorbs some photons. That energy can free electrons inside the material. An internal electric field helps separate charges. The resulting current flows through metal contacts. Many cells connect to form a larger module. An inverter can convert DC electricity into AC power. #SolarPanel #SolarEnergy #Photovoltaic #SolarCell #howitworks
