MIT engineers have worked out a computational model which shows how solar energy can be more or less funneled before it’s captured, ensuring an efficient and effective solar energy capturing mechanism.

Organic Solar Cells One Step Closer To Success
2012-06-15 13:24:53

Organic solar cells have long been a promising alternative to conventional solar cells, but their low efficiency, low stability, and low strength have kept them from widespread commercial use.

Physicists have trapped and cooled exotic particles called excitons so effectively that they condensed and cohered to form a giant matter wave.

Single Nanomaterial Yields Many Laser Colors
2012-04-30 07:46:35

Engineers at Brown University and QD Vision Inc. have created nanoscale single crystals that can produce the red, green, or blue laser light needed in digital displays.
