anionic conjugated polyelectrolyte as a semiconducting,perovskite defects are a major hurdle in the efficiency and stability of perovskite solar cells (pscs). while various defect passivation materials have been explored, most are insulators that hinder charge transport. this study investigates the potential of two different π-conjugated polyelectrolytes (cpes), mps2-tea and pcpdtbt2-tma, as semiconducting additives in pscs. the cpes differ in

efficient near-infrared anionic conjugated polyelectrolyte

in this work, an anionic conjugated polyelectrolyte (pcp-so3k), in which the backbone contains alternating 4,4-bis-alkyl-4h-cyclopenta-[2,1-b;3,4-b′]-dithiophene and benzene structural units and the charges are provided by pendant sulfonate groups, was synthesized. the ionic nature of pcp-so3k renders it sol

anionic polyelectrolyte modified perovskite composite,it is well known that the biggest advantage of aops is high efficiency, while the k values of 1 o 2 with various contaminants (10 3-10 7 m −1 s −1) are much lower than ·oh and so 4-· (10 5-10 9 m −1 s −1), which leads to a significantly lower measured redox potential of 1 o 2 (0.81 v vs. nhe) than ·oh (1.8–2.7 v vs. nhe) and so 4
