Summary:
- This article is about the development of a new type of solar panel that can generate electricity even when the sun is not shining.
- The new solar panels use a process called "radiative cooling" to generate electricity at night by absorbing heat from the surrounding environment and converting it into electrical energy.
- This technology could help provide electricity in areas that don't have access to the power grid, and it could also be used to supplement traditional solar panels during the day.
