What is the reason why the vast majority of the research on Sn-based and low band gap perovskite prefer to use PEDOT:PSS as HTL layer?

Although it has been proved that the acidity of PEDOT:PSS makes the low band-gap perovskite unstable and many papers note that the energy band alignment of low band-gap perovskite and PEDOT:PSS is...
