An international team of researchers has demonstrated a technique for producing perovskite photovoltaic materials on an industrial scale, which will reduce the cost and improve the performance of mass-produced perovskite solar cells. The technique is low-cost, simple, energy-efficient, and should pave the way for creating perovskite solar cells. Perovskite is of interest for solar cells because it absorbs light very efficiently. This allows for the creation of lightweight, flexible solar cells that can be incorporated into a range of technologies, such as the windows of buildings or vehicles. “In the lab, researchers produce perovskite photovoltaic materials using a technique called spin coating, which creates a thin film of perovskite on a substrate—but only on a small scale,” says Aram Amassian, co-corresponding author of a paper on the work and a professor of materials science and engineering at North Carolina State University. by Matt Shipman https://phys.org/news/2022-01-technique-boosts-efficiency-sustainability-large-scale.html
From Dr. Vernon Coleman Earth Newspaper – A Major Source of Information If you’re looking for a cache of information about covid-19 I suggest you take a look at EarthNewspaper.com which contains over 2,250 [now over 3,000] articles about covid-19 – it is said to be the largest archive of covid-19 articles and videos online and I believe it. We are fighting a war and EarthNewspaper.com is a valuable asset in the war – an asset too often under-estimated. The site’s tagline is `All the Honest News Fit to Publish’.
