A research team from Brown University has made a major step toward improving the long-term reliability of perovskite solar cells, an emerging clean energy technology. In a study to be published on Friday, May 7 in the journal Science, the team demonstrates a “molecular glue” that keeps a key interface inside cells from degrading. The treatment dramatically increases cells’ stability and reliability over time, while also improving the efficiency with which they convert sunlight into electricity.

“There have been great strides in increasing the power-conversion efficiency of perovskite solar cells,” said Nitin Padture, a professor of engineering at Brown University and senior author of the new research. “But the final hurdle to be cleared before the technology can be widely available is reliability—making cells that maintain their performance over time. That’s one of the things my research group has been working on, and we’re happy to report some important progress.”

Perovskites are a class of materials with a particular crystalline atomic structure. A little over a decade ago, researchers showed that perovskites are very good at absorbing light, which set off a flood of new research into perovskite solar cells. The efficiency of those cells has increased quickly and now rivals that of traditional silicon cells. The difference is that perovskite light absorbers can be made at near room temperature, whereas silicon needs to be grown from a melt at a temperature approaching 2700 degrees Fahrenheit. Perovskite films are also about 400 times thinner than silicon wafers. The relative ease of the manufacturing processes and the use of less material means perovskite cells can be potentially made at a fraction of the cost of silicon cells.

autonomous air vehicle company ehang unveils ‘baobab’, a large tree-like tower and landing platform for its EH216 passenger drones. designed by giancarlo zema design group (GZDG) with sustainability at the core, photovoltaic panels on the vertiports will generate energy and independent plug-and-play charging points will recharge the drones wirelessly. currently in the development stage, ehang and GZDG hope to enter the emerging global eco-tourism sector with hubs being planned for a lakeside site in china’s zhaoqing city as well as in the maldives, the united arab emirates, and italy.

And as well as producing less waste, insects can also live off food and biomass that would otherwise be thrown away, says Collins, contributing to the circular economy, where resources are recycled and reused. Insects can be fed agricultural waste, such as the stems and stalks from plants that people don’t eat, or scraps of food waste. To complete the recycling chain, their excrement can be used as fertiliser for crops.

Insects are a nutrition-dense source of protein embraced by much of the world. Why are some of us so squeamish about eating them?

“This work confirms that there is a link between air pollution and how well the aging brain works,” senior study author and Columbia University researcher Andrea Baccarelli told The Guardian. “These shorter-term effects are reversible: when air pollution clears, our brain reboots and starts working back to its original level. However, multiple occurrences of these higher exposures cause permanent damage.”

Thankfully, it’s reversible.

Innovation in Uganda.

Access to clean water may be a right, but it’s often hard to come by. Contaminated water kills. Henry Othieno and Saudah Birungi have developed eco-friendly filters for use in schools and homes. They turn dirty lake water into drinking water.

Excellent! Technology is available to make real change. Support efforts to clean the seas and use renewable energy sources.

Tired of hitting these floating objects during his races and seeing heavenly places turn into landfills, a French ocean adventurer Yvan Bourgnon decided to fight against this global scourge. He and his team have designed Manta, a giant, plastic-eating catamaran powered by renewable energy. The sea vessel literally scoops up plastic garbage and converts it into fuel to help power the boat.

The Biden administration on Monday said it has approved a major solar energy project in the California desert that will be capable of powering nearly 90000 homes.

The $550 million Crimson Solar Project will be sited on 2000 acres of federal land west of Blythe, California, the Interior Department said in a statement. It is being developed by Canadian Solar (CSIQ.O) unit Recurrent Energy and will deliver power to California utility Southern California Edison.

The announcement comes as President Joe Biden has vowed to expand development of renewable energy projects on public lands as part of a broader agenda to fight climate change, create jobs and reverse former President Donald Trump’s emphasis on maximizing fossil fuel extraction.
