Perovskite Tandem Solar: Breaking the 30% Efficiency Limit #351
Q: Tell us a little bit about your background and how you ended up starting Swift Solar.
Joel discusses his MIT PhD work and solar research, the motivation behind pursuing Perovskite Tandems, and the step to spin out Swift Solar to commercialize the technology.
Why Community Microgrids Are Illegal in Most of the US #350
Q: Cameron, paint us a picture of who are the shining stars and organizations getting microgrid policy and deployment right.
Several jurisdictions and groups show promise, including California projects through the Clean Coalition and Agile Electrification, and the city of Ann Arbor exploring supplemental energy utilities; the key is cooperative models, exemptions from wires laws, and shared storage solutions.
