We wanted to fabricate a perovskite solar cell using methylammonium lead iodide as the absorber material. But the popular HTL and ETL layers are very expensive and we can't afford those. Also, we don't have the facility to synthesize them too. Could somebody please suggest a few low-cost HTL and ETL materials that we can purchase to use with methylammonium lead iodide perovskite?
Have you looked at suppliers like Borun or Xi'an? Spiro and PTAA is relatively cheaper from these suppliers. Also for the ETL, perhaps you could use the chemical bath deposition technique.
Dear Titu Thomas
I recommend ZnO as a ETL and Cu2O as a HTL for CH3NH3PbI3 based solar cells. Their synthesis are very simple and low cost.
How much efficiency are you looking for? Go for carbon based device for lowering down your cost.
Hi Titu,
You may make an inquiry at Alfa Chemistry, they offer you advices and kinds of good-quality materials.

You can also try HTL-free approach in which HTL layer is no longer existing in the cell structure.
