What is Nankai Potassium-Tartrate NiOx Perovskite Modules?

Solar cells turn light directly into electricity. Perovskite solar cells use a special crystal-structured compound as the layer that absorbs light, but they face problems such as long-term stability and the cost and effort of manufacturing them. Large perovskite panels need thin, even layers, including a nickel oxide layer that helps pull electrical charge out uniformly, and such layers are hard to make both complete and chemically useful. This research result describes a way to grow that nickel oxide layer in a chemical bath, using potassium tartrate to control how fast the nickel oxide crystallizes so the film forms dense and conformal. It was published in Nature Photonics in September 2026 by authors at Nankai University, with reported module efficiencies of 23.42% (17.7 cm2) and 21.97% (81.5 cm2).
