In-situ fast oxidation of spiro-OMeTAD hole transport layers under ambient indoor lighting compatible with air-processed perovskite solar cells

Chem. Commun., 2025, Accepted Manuscript DOI: 10.1039/D5CC01956G, Communication Guangyao Liu, Xin Li Doped spiro-OMeTAD with lithium salt and 4-tert-butylpyridine is widely employed in perovskite solar cells. Under low-intensity indoor light, photogenerated hole transfer from the perovskite to the hole transport layer drives...
