Ammonium meta tungastate hydrate (AMH) & NaCl etc can be used for doping into PEDOT:PSS to enhance stability of perovskite solar cells. What are the detailed methods of doping these materials into PEDOT:PSS?
You can find the doping techniques of PEDOT:PSS by salts in the thesis given in the link: http://shura.shu.ac.uk/12475/7/Cranton%20Metal%20salt%20modified%20PEDOT.pdf
You can mix the powder of these materials and then disperse them in a suitable solution or you can disperse the PEDOT:PSS in a solution and add to it the salt powder with the suitable mixing ratio.

You can refer to the following references, talked about the chloride salts doped PEDOT:PSS for perovskite solar cell. (10.1021/acsami.7b14592, 10.1016/j.nanoen.2018.09.023)
