Mission Critical | Silicon Solar Is Hitting Its Limit. What Comes Next? | Blake Martin and Jack Manzella of Sofab Inks
Silicon solar is close to its efficiency limit, and the AI build-out needs more power than ever. Blake Martin (CEO) and Jack Manzella (COO) of Sofab Inks are working on what comes next: perovskite solar layered on top of silicon. The catch is lifespan. Perovskite already performs, but it hasn't proven it can last the 25 to 30 years lenders need to see to finance it. Sofab, which closed a $6M seed round this summer, makes tin-oxide inks that replace C60, an off-the-shelf layer that is one of the main reasons perovskite cells don't last yet. This week's episode comes from Mission Critical, our series on the industries American prosperity runs on. We recorded it in person at Sofab's lab in Louisville. Blake and Jack explain why perovskite stacks on silicon instead of replacing it, why lenders care more about lifespan than record efficiency, and the test result they were sure was an error. Peter Armstrong, their CTO, closes the episode with a tour of the lab. Get new episodes in your inbox: middletech.com/subscribe Mission Critical is hosted by Logan Jones and Alex Mercer.
