Joel Jean — CEO @ Swift Solar

Background

About

Joel is the CEO and co-founder of Swift Solar, a US manufacturer pioneering high-efficiency perovskite tandem solar technology. Swift's perovskite-silicon tandems are designed to break through the efficiency limits of conventional silicon and redefine the performance ceiling of solar energy. Swift's mission: unlock the full potential of solar energy.

Taiwanese-American, born and raised in Ohio. Stanford undergrad → MIT EECS PhD. Before Swift, Joel was Executive Director of the Tata-MIT GridEdge Solar research program and co-authored the MIT Future of Solar Energy study. Forbes 30 Under 30 in Energy.

In March 2026 Swift acquired Meyer Burger's HJT manufacturing assets and IP — combining American perovskite leadership with German silicon expertise to scale gigawatt-scale US solar manufacturing.
