How solar panels could cool our homes while harvesting energy

One day, rooftop solar panels could pull double-duty: harvesting energy from the Sun while also cooling the house below. Scientists have created a device that combines two technologies to do exactly that. And while it’s an early prototype, it’s a promising step toward solving the world’s many energy needs.Most people are familiar with the concept of solar harvesting, or absorbing energy from the Sun and converting it into power. There is also a reverse process called radiative
