David Fenning

Francine Berman Professor

Chemical and Nano Engineering Department at UC San Diego

I completed a Ph.D. in Mechanical Engineering from the Massachusetts Institute of Technology in 2013 based on my work on high-temperature defect engineering of metal impurities in silicon solar cells.

After finishing my Ph.D., I had the unique opportunity to put it straight to work. I consulted at silicon solar technology company 1366 Technologies, working with their talented R&D team toward deploying solar at the cost of traditional coal-based power.

To address the intermittency challenge that solar power faces, I returned to MIT to work on solar energy storage technologies, including solar-to-fuel electrochemistry. In MIT's Electrochemistry Energy Lab, I pursued projects in photoelectrochemistry and solar-to-fuels research based on a variety of materials platforms and device architectures.
