New perovskite solar cells are able to retain around 95% of their performance after extended heat testing, according to a new study.
A research team at the University of Manchester has enhanced the stability of perovskite solar cells by fine-tuning the small molecules that coat their surface. These molecules, known as amidinium ligands, effectively ‘glue’ the perovskite structure together.
Professor Thomas Anthopoulos, professor of emerging optoelectronics at the University of Manchester, who led the research, said: “This could overcome one of the last major hurdles facing perovskite solar cell technology and ensure it lasts long enough for large-scale deployment.’
Perovskite has long been hailed as a game-changer for the next generation of solar power. Solar cells featuring a perovskite-structured crystal compound are excellent at absorbing sunlight and converting it into electricity. However, while they are very efficient, compared with traditional silicon cells, they lack stability and...
