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. One...

Well, a little bit, anyway.

I mean, the construction is completely different, the electrolyte is different, the substrate is different. It's still a "battery," though, so it still has all those elements. I know that paper is made from wood, but that doesn't mean it IS wood. They didn't just take a carbon-zinc battery and stick a piece of wood in the middle, or between the battery and the can.
"Dr. Liangbing Hu, Teng Li, Hongli Zhu, and the rest of the research team used microscopic wood fibers that have been flattened out into thin sheets and coated with a layer of tin. The team also used sodium instead of lithium to make the battery more environment-friendly

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.
