@skyfaller @kelbot 2/2 work BETTER (and wouldn't destroy perfectly good solar panels like the stanford one) but I can't imagine you'd be able to generate anything close to regular PV cells.
There are claims in the article that Zn4Sb3 also has some photovoltaic properties. I can't find a good source on that, but if true it MAY work better than a simple Thermoelectric generator. If it doesn't, I don't see this going anywhere outside of free energy scammers on YouTube.
@skyfaller @kelbot if i was feeling snarky (I am), I would say that these 'solar panels' make about as much sense as running a website off of solar panels - theoretically a good idea, practically just a gimmick.
