Solar Cells Made From a Spreadable Nanoparticle Paste

An anonymous reader writes "Researchers at Notre Dame have created a nanoparticle paste, which acts as the main ingredient in solar cells that are very easy to construct. In a short video clip, they can be seen assembling a functional solar cell with little more than a heat gun, tape, and some binder clips. The paste is made from a mix of t-butanol, water, and a mix of cadmium selenide with cadmium sulfide nanoparticles. So far, the experimental devices are not nearly as efficient as standard solar cells, but they were just developed. If the materials were slightly less toxic, it might even be a project that kids could do at home."

"If the materials were slightly less toxic, it might even be a project that kids could do at home."

30+ years ago this probably would have been a kids project. But now we have chemical free chemistry sets.

I'm sure he's as mad as a hatter. ;)
