Slashdot - One of the problems with solar panels is that they
don't generate electricity at night, so we have to store the electricity
they generate during the day to power things during the evening. That
works fine, but what if we could develop solar panels that did generate electricity at night? It's possible, and the way it works is pretty surprising.
Researchers from the University of California, Davis explain in a new paper
that was just published in the journal ACS Photonics that if you want
to create a solar panel that generates electricity at night, then you
just have to create one that operates the exact opposite way solar
panels work during the day. It's being referred to as the 'anti-solar
panel.'
The paper's author explains to Inverse that as heat flows from
Earth to outer space, "it's picking that off and converting that into
power," using a thermoradiative cell instead of a photovoltaic cell, and
he's now working with his team to develop prototypes.
And another paper in September from Stanford researchers also explored the idea of generating electricity at night.
