New class of nanoparticle brings cheaper, lighter solar cells outdoors

RSSfeed

A new class of solar-sensitive nanoparticle that outshines the current state of the art has been developed and tested by researchers. This new form of solid, stable light-sensitive nanoparticles, called colloidal quantum dots, could lead to cheaper and more flexible solar cells, as well as better gas sensors, infrared lasers, infrared light emitting diodes and more.
