By optimizing polymerization conditions, we were able to achieve a polymer brush layer with a weight loss fraction of up to 43.3%, which was higher than those of other polymers with carboxyl or primary amine end groups. Moreover, a broad range of vinyl monomers, including styrene, methacrylate, and methyl methacrylate, can be applied using the FRPIGt method to modify Al NPs. In addition, the FRPIGt method can be extended to photoinduced organocatalyzed atom-transfer-radical polymerization.

However, there are numerous surface or bulk defects in SnO2, working as charge recombination centers to degrade device. Here, an electroactive and self-healing polyurethane (PHNN) was designed by integrating conjugated unit – naphthalene diimide (NDI) into a typical polyurethane backbone. Numerous hydrogen bonds and π interactions in PHNN work as non-covalent interactions to endow this polymer with superior self-healing properties. PHNN contains lots of aliphatic amine and carbonyl groups, which effectively passivate the defects in SnO2. The π stacking of NDI units will facilitate electron delocalization, endowing PHNN with electrical activity compared with traditional polyurethane. Doping SnO2 with PHNN can improve the conductivity and reduce the work function of SnO2 layer, which is conducive to efficient charge extraction and transport. Using PHNN doped SnO2 as ETL for PM6: Y6 and PM6: BTP-eC9 based inverted organic solar cells can achieve a high efficiency of 17.16% and 17.51%, respectively. Devices containing doped SnO2 ETL show significantly improved efficiency and stability.
