Solar Panels Inspire LED Breakthrough

Light bulbs that last 100 years and fill rooms with brilliant ambiance may become a reality sooner rather than later, thanks to a National Renewable Energy Laboratory discovery. NREL scientists found a way to generate a tricky combination of green and red that may just prove to be the biggest boost for illumination since Edison’s light bulb. Green isn’t just a symbol of environmentalism, it is a real color, and a desperately needed one for researchers looking... Read More

IBM Creates Solar Cell Comprised Mostly Of Earthly Elements

IBM announced it has built a solar cell — where the key layer that absorbs most of the light for conversion into electricity, is made entirely of readily-available elements — that set a new world record for efficiency and holds potential for enabling solar cell technology to produce more energy at a lower cost. Comprised of copper (Cu), tin (Sn), zinc (Zn), sulfur (S), and/or selenium (Se), the cell’s power conversion demonstrates an efficiency of 9.6 percent... Read More
