MIT Breaches The 34% Solar Efficiency Barrier

Some much needed good news from Boston. Killing two birds with one stone, that’s what MIT seems to have achieved by applying a cheap pentacene coating to solar cells. One of the birds killed might be the theoretical Shockley-Queisser efficiency upper limit of 34% assumed to apply to any solar cell, based on the idea that a single photon could merely knock a single electron out of atomic orbit. The people from MIT now have transfered the game of carom billiards to the realm of sub-atomic particles and are able to hit two electrons with a single photon, a real game changer in the world of solar cells.
