Abstract

New soluble, narrow bandgap bithiophene‐based conjugated polymer poly[3‐(1,4‐dihydro‐5,8‐didodecanoxy‐1,4‐methano‐naphthalen‐6‐yl)‐2,2′‐bithiophene‐5,5′‐diyl(2‐cyano‐1,2‐ethenediyl)‐1,4‐diphenylene(1‐cyano‐1,2‐ethenediyl)] (PBT‐PDCN) has been synthesized by Knoevenagel polycondensation method. PBT‐PDCN exhibits high solubility in common organic solvents. Optical studies show that the higher‐energy absorption band of PBT‐PDCN is red‐shifted with increasing polarity of solvents from toluene to THF, and from solution to solid film. Electrochemical characterizations revealed that polymer PBT‐PDCN has a low bandgap. The hole mobility was found to be 1.4 · 10^−4^ cm^2^ V^−1^ s^−1^. Bulk heterojunction solar cells have been fabricated using blends of PBT‐PDCN with PCBM in different ratios. The best solar cell performance obtained was based on the blend of PBT‐PDCN with PCBM in 1:3 weight ratio with the power conversion efficiency reaching 0.71%. The photocurrent action spectrum showed a broad curve between 400 nm and 700 nm, with an external quantum efficiency (EQE) maximum of 20% at 570 nm, matching the PBT‐PDCN absorption spectrum very closely. magnified image
