perovskite

Perovskite is quickly gaining on silicon in the solar cell field, but it has one major drawback – durability. Now, a new treatment has been shown to keep perovskite solar cells working at 99% of their efficiency after 1,000 hours of use.Silicon solar cells may have had a head start of several decades, but perovskite is rapidly closing the gap after only about 15 years. Not only is its efficiency approaching that of silicon, but it's also cheaper, lighter and more flexible.But of course, there’s a catch – perovskites tend…

This has the potential to transform the renewable energy industry. Despite this potential, the current layer-by-layer manufacturing method presents obstacles that have prevented the widespread commercialization of…

Perovskites are one of the most promising new materials for solar cell technology. Now engineers at the University of Rochester have developed a new way to more than triple the material’s efficiency by adding a layer of reflective silver underneath it.For the better part of a century, silicon has been the go-to material for making solar cells, thanks to its abundance and efficiency in converting light to an electrical current. But in just the last decade, a new contender has rapidly risen through the ranks – perovskite,…

Scientists have proven that an ultrathin protective coating can protect a perovskite solar cell in space, according to newly published research from the US Department of Energy’s National Renewable Energy Laboratory (NREL). Perovskite solar cells in space Space-based solar power – collecting solar power in space using solar power satellites and sending that power back to Earth – is being investigated by the US, China, the UK, France, Japan, and other countries.

By Dalian Institute of Chemical Physics, Chinese Academy Sciences September 9, 2022Lattice distortion in lead halide perovskite quantum dots leads to a fine structure gap and coherent exciton quantum beating. Credit: DICPScientists just reported the utilization of lattice distortion in lead halide perovskite quantum dots to control their exciton fine structure. The researchers were led by Prof. Kaifeng Wu from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS), in collaboration with…

Perovskite is poised to become a major material for solar cells, but before then it needs to overcome a major durability issue. Engineers at Princeton have unveiled a new perovskite solar cell design that tests suggest could last as long as 30 years of real-world use.Silicon has been the go-to material for solar cells for decades, but in the last 15 years or so perovskites have been quickly catching up. They’re approaching the efficiency of silicon but are cheaper to make, lighter and more flexible.The problem, however,…
