Moisture-resistant perovskite solar cell with 25.14% efficiency

An international research team has fabricated a perovskite solar cell using sulfur-based additives to improve its resistance to moisture. The device not only achieved high efficiency levels but was also able to retain about 96% of its efficiency after 1,000 h. One of the main challenges for the scientific community and the PV industry to bring perovskite solar cells (PSCs) to commercial production is the need to improve moisture stability. Protecting the perovskite layer from moisture is key to preventing excess water from forming on the layer itself, as it can damage the crystallinity of the ...
