Plasmonic Nanostructures Could Prove a Boon To Solar Cell Technology
Zothecula writes "Researchers at the University of Pennsylvania have found a way to harvest energy from sunlight more efficiently, with the help of so-called plasmonic nanostructures. The new findings suggest that plasmonic components can enhance and direct optical scattering, creating a mechanism that is more efficient than the photoexcitation that drives solar cells. The development could therefore provide a real boost to solar cell efficiency and lead to faster optical communication."
Every one of the inventions is being pulled forward. It is clear you have no idea what's available out there. Thin film is beginning to dominate commercial installation, in fact it's so much better that it's very difficult to even purchase thin films any more because all the production is allocated to commercial installations. Other techniques are out there and being used, the better the cell the more likely it'll be relegated to commercial installation. Most of what's available for retail purchase is the output of older cell lines that are no longer competitive on the commercial side.
Solar is now significantly below $1 a watt and is approaching the point where in commercial installations it's amortized cost is approaching that of coal power. It's already cheaper than nuclear on all fronts.
