An antisolvent-seeding strategy enhanced self-assembled monolayer formation, enabling the growth of high-quality perovskite top cells on flexible Cu(In,Ga)(S,Se)2 bottom cells. A 1 cm2 flexible tandem solar cell produced using this approach achieved a certified efficiency of 23.8% and is photostable and mechanically durable.

This paper demonstrated that low-polarity solvents provide a thermodynamically favourable environment for the adsorption of SAMs.
