Researchers have identified a key mechanism responsible for the lower efficiencies of organic solar cells and shown a way that this hurdle might be overcome.

Earth's floating solar power capacity has grown one-hundredfold in the last five years.

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

Our research identified three key lessons.

New thermal photovoltaics reflect 99% of the energy they can't convert to electricity. They could help cut the price of storing renewable energy as heat.

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.
