George Cove, a forgotten solar power pioneer, may have built a highly efficient photovoltaic panel 40 years before Bell Labs engineers invented silicon cells. If proven to work, his design could lead to less complex and more sustainable solar panels.
So, thermocouples are commonly used in industry to make temperature probes, typically in the form of a coil of wire containing two conductors of different metals. I wonder if it’d be possible to get ahold of some thermocouple wire and put together a solar cell at home?
