How to find the effective delay time of anti-solvent dripping/solvent washing in perovskite solar cell irrespective of solvents?

06 June 2018 1 4K Report

Dear Sir/Madam,

The dripping of anti-solvents like toluene, CB etc.. on perovskite material while spinning is prominent method to obtain good quality thin film. Time of dropping is so crucial to achieve certain morphology and crystalline. It also depends with spin speed and acceleration. But how to find the effective delay time of anti-solvent dripping/solvent washing in perovskite solar cell irrespective of solvents?
