In the two-step synthesis of perovskite solar cells, why does the perovskite layer go off (evaporates) after removing from CH3NH3I-Isopropanol soln?

Two step methods consist of, 1) spin coating PbI2-DMF solution (462 mg/ml) on substrate and then annealing to form PbI2 layer 2) dipping the PbI2 coated substrate in CH3NH3I- Isopropanol(IPA)...

Dear yashad

Its hard to produce layer through spray pyrolysis as temperature constraints might occured during process as methyl ammonium iodide decomposition temperature is might high.

Vipin Shrotriya

may be in high range and depends on your arrangement

Adam Ginsburg

There are papers about spray pyrolysis of perovskites. (most famous one in EES)

It is possible if you keep the subsrate temperature between 90-110C
