Scientists have discovered a way to power a light by using the cold of outer space, which could eventually be used to create the nighttime counterpart to solar energy. As the technology improves, we see it enabling solar panels that work at. . There's a stark contrast between the freezing temperatures of space and the relatively balmy atmosphere of Earth, and that contrast could help generate electricity, scientists say – utilising the same optoelectronic physics used in solar panels. Using an inexpensive thermoelectric device, they're able to harness the cold of space without an active heat input. By. . Thanks to a new breakthrough, this is no longer a fantasy — scientists have created a photovoltaic (PV) cell that is able to generate power at night through a process known as radiative cooling.

Could solar power generate electricity from the cold night sky?
For many of them, solar power is their potential energy saviour – at least when the sun is shining. Technology to store excess solar power during the dark hours is improving. But what if we could generate electricity from the cold night sky? Researchers at Stanford and UCLA have just done exactly that.
Do solar panels produce electricity at night?
No, standard solar panels don't produce electricity during the night since they require sunlight to do that but new technology such as anti-solar panels and radiative cooling PV cells, can generate a little bit of power in the dark by converting radiation from heat into electricity. Solar power is one of the most renewable sources of energy.
Could cold space power a light?
Scientists have discovered a way to power a light by using the cold of outer space, which could eventually be used to create the nighttime counterpart to solar energy. Using an inexpensive thermoelectric device, they're able to harness the cold of space without an active heat input.
Can LED light bulbs produce electricity if there's no sun?
No sun? No problem. A new thermoelectric device can generate electricity for an LED light bulb even during the blackest night, according to a report by researchers. The secret is using a phenomenon known as radiative cooling, which happens when surfaces on the ground radiate heat into the atmosphere.
