Researchers use ethylene glycol to produce cheaper solar cells
4:55 AM MDT | July 5, 2013 | Francinia Protti-Alvarez
Engineers at Oregon State University (OSU; Corvallis, OR) have determined that ethylene glycol (EG), commonly used in antifreeze products, can be a low-cost solvent that functions well in a continuous-flow reactor–an approach to making thin-film solar cells– that is easily scaled up for mass production at industrial levels, the university says. The technology being developed at the university uses EG in meso-fluidic reactors that can offer precise control of temperature, reaction time, and mass transport to yield better crystalline quality and high...
