A series of four new oligomeric derivatives of NFA , NFA(S) , NFA(Se) and NFA(N) with terminal perylene diimide groups modified with heteroatoms of S, Se, and N, were successfully synthesized and fully characterized by a variety of physicochemical methods. Due to deep LUMO levels, all compounds have an electron-acceptor character, which allows them to perform as electron transport compounds in perovskite solar cells of p-i-n architecture. The highest efficiency of 17.23 % was delivered by the solar cells with NFA(Se) electron transporting layer. [Display omitted] • A series of new oligomers with terminal perylene diimide groups modified with heteroatoms of S, Se, and N, were synthesized. • Optical and electronic properties of the new compounds were studied. • All the compounds were studied as new type materials for electron transport layer for perovskite solar cells. • The highest efficiency of 17.23 % was delivered by the solar cells with NFA(Se) electron transporting layer.
