Solar cells that generate electricity at night
Solar panels can traditionally only produce power when the sun shines, but new developments are changing that.Scientists have developed solar panels that can work in the dark and be powered by rain.These innovations could transform solar into a 24-hour power source, helping with the world’s transition to net-zero emissions.

Stanford engineers invent a solar panel that generates electricity at nightAt night, solar panels turn the table and emit photons The new technology takes advantage of a surprising fact about solar panels. The invention taps into a source of energy that’s easily overlooked . It all comes down to radiative cooling . Developing this technology poses several engineering challenges .
Harvesting energy from the temperature difference between photovoltaic cell, surrounding air leads to a viable, renewable source of electricity at night.
Researchers at Stanford modified commercially available solar panels to generate a small amount of electricity at night by exploiting a process known as radiative cooling, which relies on, no lie, .
At nighttime or on cloudy days, solar cells simply can't access enough of the sun's energy. This adds to the expense of a solar power system, since it can't generate power 24/7.
