(3)White crystal is placed in the vacuum drying chamber that temperature is 100 DEG C again and keeps the temperature 24h, that is, obtains dry methylpyridinium iodide Ammonium white crystal;
(4)FT0 electro-conductive glass is successively cleaned by ultrasonic 10min with distilled water, alcohol and acetone, then again on electro-conductive glass Spin coating Ti02Porous support layer, rotating speed are 3500 rpms, and spin-coating time is 60 seconds;
(5)Then the sheet glass of the good shelf layer of spin coating is placed in heating plate, 30rain is kept at 500 DEG C, makes Ti02Crystallization;
(6)Weigh tin halides to be dissolved in DMF with methylpyridinium iodide ammonium, be hybridly prepared into certain density precursor solution, will prepare Good precursor solution is placed in sonic oscillation instrument sonic oscillation 10min to promote the abundant dissolving and reaction of reactant;
(7)Precursor solution is spun on Ti02On porous support layer, rotating speed is 1000-3500 rpms, and spin-coating time is The sheet glass of the good precursor solution of spin coating, is then placed in heating plate by 60-80S, is after 5-8min is kept at 100-150 DEG C .
Preferably, the step(7)Rotating speed be 2800 rpms, spin-coating time 80S, then by the good forerunner of spin coating The sheet glass of liquid solution is placed in heating plate, and 8min is kept at 120 DEG C.
The method of the invention prepare without slicker solder perovskite thin film, there is minimum energy gap, its knot Brilliant performance is better than the perovskite thin film of other compositions.
