A California-based company that liquid-processes light-absorbing materials (other than silicon) into nano-size particles for so-called solar ink, and was founded by Brian Korgel, Matthew Van Winkle Regents Professor in Chemical Engineering, said its technology is only three to five years from becoming a reality. Spun out of The University of Texas at Austin, Innovalight has lofty goals to make solar cells both paintable and sprayable. That way building developers could coat massive surfaces with energy-generating compounds of copper indium gallium selenide.
