Episode Description from the Publisher

Perovskite solar has promised a revolution for over a decade, so is it finally real? Matt and Sean talk with Joel Jean, co-founder and CEO of Swift Solar, the US startup spun out of MIT and Stanford. Joel explains how stacking a perovskite film on top of silicon lifts a solar cell's efficiency ceiling from 30 percent to about 45 percent. He also breaks down the three "tooth fairies" every new solar technology has to solve: performance, lifetime, and cost. So is perovskite tandem solar finally ready for your roof? Or is 25 year durability still one miracle away?Chapters:00:00: Intro03:20: Joel Jean Interview41:02: The Super Soaker MailbagWatch on YouTube: https://www.youtube.com/watch?v=vtmX0st3uOkSupport the show directly: https://stilltbd.fm/join/Audio version of the podcast: https://stilltbd.fmYouTube version of the podcast: https://www.youtube.com/@stilltbdYouTube membership: https://www.youtube.com/channel/UC4-aWB84Bupf5hxGqrwYqLA/joinGet in touch: https://stilltbd.fm/contact/Follow us on:Mastodon - https://mastodon.social/@mattferrellBluesky - https://bsky.app/profile/mattferrell.bsky.socialUndecided with Matt Ferrell: https://www.youtube.com/@undecidedtechnology Hosted on Acast.
