Low-priced plastic photovoltaics

Photovoltaic devices, which tap the power of the sun and convert it to electricity, offer a green—and potentially unlimited—alternative to fossil fuel use. So why haven't solar technologies been more widely adopted?

UCLA scientists double efficiency of novel solar cell

Nearly doubling the efficiency of a breakthrough photovoltaic cell they created last year, UCLA researchers have developed a two-layer, see-through solar film that could be placed on windows, sunroofs, smartphone displays ...

Putting more science into the art of making nanocrystals

Preparing semiconductor quantum dots is sometimes more of a black art than a science. That presents an obstacle to further progress in, for example, creating better solar cells or lighting devices, where quantum dots offer ...

Jagged graphene edges can slice into cell membranes

(Phys.org) —A collaboration of biologists, engineers, and material scientists at Brown University has found that jagged edges of graphene can easily pierce cell membranes, allowing graphene to enter the cell and disrupt ...
