Increasing the Li-TFSI doping concentration in Spiro-OMeTAD enables efficient and stable perovskite solar cells
A Li-TFSI/12-crown-4 chelate not only enhances the Li-TFSI solubility, increasing doping concentration from 50 to 80 mol%, but also inhibits Li + migration, hygroscopicity and pinholes. Ultimately, PSCs achieved a PCE of 23.99% and improved stability.
