IBM Creates “Cooling Liquid” Which Significantly Reduces Costs For CPV

IBM announced a research breakthrough in PV technology that could significantly reduce the cost of harnessing the Sun’s power for electricity. By mimicking the antics of a child using a magnifying glass to burn a leaf or a camper to start a fire, IBM scientists are using a large lens to concentrate the Sun’s power, capturing a record 230 watts onto a centimeter square solar cell, in a technology known as concentrator photovoltaics, or CPV. That energy is then converted... 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
