Is free-standing actually a good thing? It seems to me if you're trying to maximize flux per unit material, you can't do much better than a flat sheet. The only problem is that the sun moves, but it seems like a free-standing array would only get slightly better performance for much greater cost.
- briancooley 18y agoFrom a related article (http://www.katu.com/news/local/28432984.html http://www.katu.com/news/local/28432984.html): If he is right, solar panels with his 3D cells would provide 500 times more light absorption than commercially-available solar cells and nine times more than cutting-edge 3D solar cells. So apparently there is some advantage to 3D cells, apparently related to multiple light interactions: "Regular solar cells are only 2D and only allow light interaction once," he said. It's still not apparent what the basis is for the 500x light absorption figure. Seems to me that the most meaningful basis is the footprint of the device, but that is not clear from any story I've read on this subject.
