I caught the Golden Globes final weekend, and the Grammys and Oscars aren’t far off. However the perfect awards, in my humble opinion, are the ten Breakthrough Applied sciences, MIT Expertise Overview’s listing of the tech that’s altering our world.
This yr’s listing dropped on Monday, and I’m delighted to share that not one, not two, however three local weather tech gadgets are featured. So for the e-newsletter this week, let’s check out a couple of of those award-winning applied sciences you’ll want to find out about. (And to honor awards season, I’ll even be assigning them to bonus—and utterly unofficial—classes.)
Tremendous-efficient photo voltaic cells
Winner: Finest Supporting Actor
Photo voltaic panels are among the many most necessary, and maybe essentially the most recognizable, instruments to handle local weather change. However one next-generation photo voltaic expertise might assist solar energy get much more environment friendly, and cheaper: perovskite tandem photo voltaic cells.
Most photo voltaic cells use silicon to absorb daylight and rework it into electrical energy. However different supplies can do that job too, together with perovskites, a category of crystalline supplies. And since perovskites and silicon take up totally different wavelengths of sunshine, the 2 supplies may be stacked like a sandwich to make one super-efficient cell.
Due to their excellent assist for conventional silicon photo voltaic supplies, super-efficient perovskite tandem cells are my winner for this yr’s Finest Supporting Actor award.
There are positively boundaries to commercializing this expertise: perovskites are tough to fabricate and have traditionally degraded shortly outdoors within the components. However some corporations say they’re nearer than ever to utilizing the supplies to remodel business photo voltaic. Learn extra concerning the expertise right here.
