Perovskite mineral is the future of solar energy cells, shows Cornell study

A solar cell made with perovskite, shown here, show promise as an energy-efficient, scalable and longer-lasting way to create solar panels. When it comes to...

Scientists create high-performing hybrid solar energy converter

In tests, the hybrid solar energy converter demonstrated 85.1% efficiency. Researchers project it to have a system levelized cost of 3 cents per kilowatt-hour. A...

New fabric could help keep you cool in the summer, even without air conditioning

Air conditioning feels great on a hot summer day, but cooling homes and buildings uses considerable electricity. Now, scientists have developed a cool new...

‘Blinking’ crystals may convert carbon dioxide into fuels

Imagine tiny crystals that "blink" like fireflies and can convert carbon dioxide, a key cause of climate change, into fuels. A team funded by the...

Covid-19 shutdown led to increased solar power output

Shutdowns in response to the Covid-19 pandemic have resulted in lowered air pollution levels around the world. Researchers at MIT, and in Germany and...

Scientists set new solar-to-hydrogen efficiency record

Researchers at The Australian National University (ANU) have achieved a new efficiency record for hydrogen cells that can convert water into hydrogen simply using...

Lasers and sticky tape triple lithium metal battery life
