Thanks, Ann. I actually especially like the idea that this spray coating can be used on other surfaces as well and allow other objects to harvest solar energy, too. It's really quite clever and not such a difficult concept to grasp. Let's see if it catches on in production. I think maybe one hurdle is that solar cells already are quite inexpensive, so maybe people might think if it ain't broke, don't fix it.
As the article states, spray coating is a fairly mature process and the ultrasonic method has quite a few advantages. But using this method to produce solar cells is a really good sounding plan. Now, if it is possible to produce the spray coated cells in a roll to roll process then there will be some fantastic increases in production capability, and it will be a great advance indeed.
Good point. Adapting glass to be flexible enough for roll-to-roll production was one of the big deals in Corning's Willow Glass, which DN covered here
Festo's BionicKangaroo combines pneumatic and electrical drive technology, plus very precise controls and condition monitoring. Like a real kangaroo, the BionicKangaroo robot harvests the kinetic energy of each takeoff and immediately uses it to power the next jump.
