Scientists Can Make Solar Cells Thinner Than Spider Silk? Well Done.

Behold some glory-be futurism nonsense right here. Scientists have made solar cells that are thin like woah, and can be wrapped around human hair. Human hair, folks.


According to  research published in  Nature Communications, a team of scientists from Austria and Japan has created these new, thin-film soar cells that are just 1.9 micrometers thick. That’s over ten times thinner than any other solar cells ever made, and is thinner than a thread of spider silk.

Made from electrodes layered onto plastic foil, the devices are also incredibly flexible, which means they can be wrapped up tight–even around a human hair–without being damaged. Tsuyoshi Sekitani, one of the researchers,explains to PhysOrg:

“Being ultra-thin means you don’t feel its weight and it is elastic… As this device is soft, it is less prone to damage by bending even if it gets bigger.

I want these up in my hair, powering my augmented reality contact lenses and operating as a portable charging station for the electronics that are in my backpack and enmeshed directly into my meat-sac.
