Small molecule dopant-free HTL with the ability to self-assemble shows a dual performance that leads to very similar efficiencies in p–i–n and n–i–p perovskite solar cells.

Engineering the intermediate adduct phase to control the crystallization of perovskites for efficient and stable perovskite solar cells
This work provides a simple and effective method to improve the performance of perovskite solar cells by replacing DMSO with FAI. As a result, the crystallinity and morphology of the perovskite layer are improved, and a PCE of 20.79% resulted with higher long-term stability.
