New strategies have been developed for producing crystalline nanostructures that emit strongly in the near infrared for nanoscale optoelectronic platforms.

Optoelectronics, based on the idea of using photons to transfer information, represents one appealing strategy to overcome the limitations of conventional device platforms. Yet silicon, the semiconductor material of choice on which billions of research and development dollars have been spent, does not even emit light in crystalline form, which is a requirement for its use in optoelectronic devices.

Paper battery?

by edsdesk

WASHINGTON (Reuters) – Ordinary paper could one day be used as a lightweight battery to power the devices that are now enabling the printed word to be eclipsed by e-mail, e-books and online news.
Scientists at Stanford University in California reported on Monday they have successfully turned paper coated with ink made of silver and carbon nanomaterials into a "paper battery" that holds promise for new types of lightweight, high-performance energy storage.
The same feature that helps ink adhere to paper allows it to hold onto the single-walled carbon nanotubes and silver nanowire films

Some ... some not.

Nanotubes Increase Solar PV Conductivity 100 Million-Fold  — Sourceable
Carbon-based nanostructures are already being used as materials in solar cells with increasing frequency, yet their ability to enhance electrical performance has thus far been hampered by limited ability to assemble orderly networks using the materials.
