Researchers at Berkeley Lab and the University of Arkansas, in cooperation with Glennoe Farms, is devising new methods for enhancing the amount of active carbon in farm lands. More active carbon means higher yields with less fertilizer and fewer pesticides.
A new conversion efficiency record for 9 millimeter-squared solar cells made of gallium arsenide was recently achieved by engineering researchers at the University of Arkansas. The new record — 14% efficiency — was achieved via the utilization of a new approach using a thin layer of zinc oxide. With the new … [continued]
Researchers at the University of Arkansas, and Arkansas State, have been developing solar cells that use alternatives to silicone for space applications. Projected efficiencies are over 40%. New funding has just been announced.
