Thin-Film Photovoltaics: Making Every Photon Count

Yvonne Carts-Powell

Researchers are turning to organic and hybrid nanoscale structures to create more cost-effective solar cells. Thin-film photovoltaic technologies that incorporate silicon are among the best options for effectively managing light.

Fifty Years of Visible LEDs

Originally a byproduct of the race to build a semiconductor laser, the visible light-emitting diode emerged in the fall of 1962. Following the “alloy road,” scientists have devised ever-brighter LEDs—and poised them to displace a century-old lighting technology.

Bird Brains: Using Picosecond Optical Tomography to Assess Neural Activity

Imaging the brains of birds with picosecond optical tomography gives scientists a fascinating look into how these animals respond to calls and songs—and insight into how the technology could be applied to humans.
