文摘

This study focuses on the syntheses of N,N-dimethyl-2-thiophenyl-3,4-fulleropyrrolidium iodide (DMFPI), poly N-methyl-2-thiophenyl-3,4-fulleropyrrolidine-co-3-hexylthiophene (MFP-co-3HT), poly N-methyl-2-thiophenyl-3,4-fulleropyrrolidine-co-3-dodecylthiophene (MFP-co-3DT), and poly N-methyl-2-thiophenyl-3,4-fulleropyrrolidine-co-3-thiopheneacetic acid (MFP-co-3TA) and their photovoltaic properties as hole transporting materials (HTMs) for use in DSSCs. The synthesized DMFPI and copolymers were characterized by ¹H NMR, MALDI TOF-mass spectrometry, UV-vis spectroscopy, and cyclic voltammetry. The DSSC devices were fabricated and their photovoltaic performances were measured using a solar simulator under AM 1.5 illumination.
