Perovskite: New LED technology surpasses the lifetime milestone

Perovskite LEDs are an emerging technology for next-generation display, lighting and communications. While perovskite LEDs can be produced simply and at low cost, they show clear technological advantages. They are lightweight ...

Researchers develop a new source of quantum light

Using novel materials that have been widely studied as potential new solar photovoltaics, researchers at MIT have shown that nanoparticles of these materials can emit a stream of single, identical photons.

Solar energy from discarded car batteries

MIT researchers have developed a simple procedure for making a promising type of solar cell using lead recovered from discarded lead-acid car batteries—a practice that could benefit both the environment and human health. ...

Quantum innovation advances low-cost alternative solar technology

A team of researchers from the University of Toronto's Faculty of Applied Science & Engineering has leveraged quantum mechanics to optimize the active layer within a device known as an inverted perovskite solar cell—a technology ...

A more environmentally friendly air conditioner

Summer is in full swing in the U.S., and people are turning up their air conditioners to beat the heat. But the hydrofluorocarbon refrigerants in these and other cooling devices are potent greenhouse gases and major drivers ...
