Solar cells are made from semiconductors whose ability to respond to light is determined by their band gaps (energy gaps). 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 … Continue reading
A new technology that was developed at the University of NSW allows traditional panels to catch more light from the blue end of the spectrum, the short wavelengths, and is expected to influence future panel production around the world. Many existing solar panels end up reflecting back the shorter wavelengths of light due … Continue reading
