Different colors have different energies, and no single semiconductor has a band gap that can respond to sunlight’s full range, from low-energy infrared through visible light to high-energy ultraviolet. Although full-spectrum solar cells have been […]

The material exhibits a high thermoelectric figure of merit that is […]
