And there are already several different approaches being developed in the field. 🤔
New photovoltaic technologies have enabled more ways of obtaining solar energy. Apart from the classic solar panels that are usually mounted on rooftops, there are solar-powered plugs, cookers, water heaters, and even portable generators. But have you ever heard about solar paint?
, Australia. Its particularity is that it doesn’t only use the sunlight but also the moisture that the sun produces when it evaporates water. By collecting water vapor from the air, the paint can eventually generate electricity. It works with nanoscale semiconductors embedded into a photon-absorbing film. More specifically, the photovoltaic paint contains nanoparticles that provide greater light absorption, including into the near-infrared spectrum. Researchers hope the technology will one day allow them to spray solar cells onto flexible surfaces, or print solar-sensitive colloidal quantum dots onto a flexible film to coat weirdly shaped surfaces, from patio furniture to an airplane wing.
