Reports on the development of a semiconductor called indium gallium nitride (InGaN) by research team led by Wladek Walukiewicz at California-based Lawrence Berkely National Laboratory that can help soak up energy from almost all of the Sun's spectrum. Possible increase in efficiency of solar cells with the use of the semiconductor; Plans of the team to try to build cheap InGaN.
