Alexi Arango: Teaching solar to take a quantum-dot leap

Alexi Arango: Teaching solar to take a quantum-dot leap

Grist is proud to present the Change Gang -- profiles of people who are leading change on the ground toward a more sustainable society and a greener planet. Some we've written about before; some are new to our pages. Some you'll have heard of; most you probably won't. Know someone we should add to the Change Gang? Tell us why. From the moment Alexi Arango walked into Professor Sue Carter's physics lab as an undergraduate at U.C. Santa Cruz and started learning how to make his own photovoltaic solar cells, he was "hooked." "It sounds really weird," he acknowledges, "but it was just so exciting to me -- on a real fundamental level -- to be working with vacuum and semiconductor fabrication equipment." Throw in the added benefit of a technology that could "benefit the environment," and Arango says he was "done." He knew where he was headed. Today, after a PhD from MIT and a sh...
