Self-powering camera: an image sensor that's also a photovoltaic cell

A team of University of Michigan electrical engineering/computer science researchers have published a paper (Sci-Hub mirror) detailing their work in creating a camera sensor (a device that converts light to electricity) that's also a solar power cell (also a device that converts light to electricity).

Promising energy storage technologies for our renewable future

When the wind is blowing, the great plains could generate enough power to supply all of America, but storing and moving energy to supply those places where the wind isn't blowing, the sun isn't shining and the tide isn't coming in is a significant technological challenge that we're still figuring out.

New materials allow 2.8l/day of solar-powered desert water-vapor extraction

Researchers from MIT, UC Berkeley, Lawrence Berkeley, and King Abdulaziz City for Science and Technology published a paper in Science describing a solar-powered device that uses a new type of metal organic framework (MOF) to extract up to three litres of water per day from even the most arid desert air.
