Semprius just unveiled an teenie solar cell that is half the size of a pinhead, which when combined with powerful inexpensive lenses can concentrate sunlight more than 11,000 times and convert it to electricity!
Semprius has been a leader in Concentrated solar research and development. In 2008 they had come out with a method to slice monocrystalline solar wafers thin enough to be flexible and partially transparent but still maintain their high solar efficiency. The slender silicon slices are then imprinted onto a substrate using Semprius’s patented microtransfer printing process.
Semprius’ patented micro-transfer printing technology brings for the first time, high performance semiconductors to virtually any surface, including glass, plastic or metal substrates or even other semiconductor wafers. By liberating the semiconductor devices from their traditional substrates, Semprius technology enables the construction of a wide variety of new products with large-area, thin, and lightweight form factors, high reliability and low cost. The resulting circuit devices have levels of performance comparable to the original semiconductor.
Smaller and more efficient! Wonderful news for Solar and alternative energy market; if only it were affordable sooner.
