The device emits a stream of single photos at room temperature and could provide a basis for optical quantum computers.

The design could someday enable a fully decarbonized power grid, researchers say.

Reducing internal losses could pave the way to low-cost perovskite-based photovoltaics that match silicon cells’ output.

As the air cleared after lockdowns, solar installations in Delhi produced 8 percent more power, study shows.

MIT’s vice president for research identifies three areas that show particular promise for climate action.

RFID-based devices work in indoor and outdoor lighting conditions, and communicate at greater distances.

Research shows that, contrary to accepted rule of thumb, a 10- or 15-year lifetime can be good enough.

Faculty in the Department of Mechanical Engineering are developing technologies that store, capture, convert, and minimize greenhouse gas emissions.

Design for system that provides solar- or wind-generated power on demand should be cheaper than other leading options.
