The study of the P3HT synthesis was carried out to investigate the effect of reaction time on thermal, optical, electronic, and morphological properties. It has been demonstrated that the variation in polymerization time over 30 min did not significantly affect the optoelectronic properties of polymers. Regarding the thermal properties, the P3HT synthesized in the shortest time presented a decomposition temperature of 20 K higher than the others. There was no difference in glass transition temperature or melting temperature, while both crystallization temperature and crystallinity content have slightly increased with polymerization time. The regioregularity of all polymers was 98%. The advantage is that a short reaction time is possible to obtain a polymer with suitable properties and, consequently, savings in the process. P3HT-30 was evaluated in a PSC active layer with the configuration of ITO/PEDOT: PSS/rrP3HT:PC71BM/Ca/Al, and PCE was 1.94%. [ABSTRACT FROM AUTHOR] |
