《Imide-functionalized acceptor-acceptor copolymers as efficient electron transport layers for high-performance perovskite solar cells》 was written by Shi, Yongqiang; Chen, Wei; Wu, Ziang; Wang, Yang; Sun, Weipeng; Yang, Kun; Tang, Yumin; Woo, Han Young; Zhou, Ming; Djurisic, Aleksandra B.; He, Zhubing; Guo, Xugang.

Electron transport layers (ETLs) are critical for improving device performance and stability of perovskite solar cells (PVSCs). Herein, a distannylated electron-deficient bithiophene imide (BTI-Tin) is synthesized, which enables us to access structurally novel acceptor-acceptor (A-A) type polymers. Polymerizing BTI-Tin with dibrominated naphthalene diimide (NDI-Br) and perylene diimide (PDI-Br) affords two A-A copolymers P(BTI-NDI) and P(BTI-PDI). The all-acceptor backbone yields both low-lying HOMO (HOMO) and LUMO (LUMO) energy levels for the polymers, which combined with their high electron mobility render P(BTI-NDI) and P(BTI-PDI) as promising ETLs for perovskite solar cells (PVSCs). When applied as ETLs to replace the conventional [6,6]-phenyl-C61-butyric acid Me ester (PC61BM) in planar p-i-n PVSCs, the PC61BM-free devices based on P(BTI-NDI) and P(BTI-PDI) achieve remarkable power conversion efficiencies (PCEs) of 19.5% and 20.8%, resp., with negligible hysteresis. Such performance is attributed to efficient electron extraction and reduced charge recombination. Moreover, the devices based on P(BTI-NDI) and P(BTI-PDI) ETLs show improved stability compared to the PC61BM based ones due to the higher hydrophobicity of the new ETLs. This work provides important guidelines for designing n-type polymers to replace PC61BM as efficient ETLs for high-performance PVSCs with improved stability. The results came from multiple reactions, including the reaction of Tris(dibenzylideneacetone)dipalladium(0)(cas: 51364-51-3Related Products of 51364-51-3)
