Ultrathin organic solar cell is both efficient and durable
9 Mar 2020 at 12:20pm
Scientists have succeeded in creating an ultrathin organic solar cell that is both highly efficient and durable. Using a simple post-annealing process, they created a flexible organic cell that degrades by less than 5% over 3,000 hours in atmospheric conditions and that simultaneously has an energy conversion ratio -- a key indicator of solar cell performance -- of 13%.
Water splitting advance holds promise for affordable renewable energy
9 Mar 2020 at 10:00am
A team has developed a less expensive water electrolysis system that works under alkaline conditions but still produces hydrogen at comparable rates to the currently used system that works under acidic conditions and requires precious metals. This advance brings down the cost of water splitting technology, offering a more viable way to store energy from solar and wind power in the form of hydrogen fuel.
