Charge extraction with hydrogen
Nature Energy, Published online: 10 February 2025; doi:10.1038/s41560-025-01705-zThe performance of kesterite solar cells is limited by poor extraction of electrons and holes and their recombination. Researchers have now discovered that annealing the device in a hydrogen-containing atmosphere can promote efficient charge extraction by redistributing certain elements like sodium and oxygen.
