WebAug 28, 2008 · A critical issue for using hybrid heterojunction concept is the interface properties which affect the exciton separation efficiency and bi-carrier transport. To improve the interface properties, we replace the insulating surfactant on TiO 2 nanorod surface with a more conductive oligomer, carboxylate terminated 3-hexylthiophene (P3HT-COOH). WebP3HT-M-COOH/CdSe NCs increased more obviously than P3HT-Z-COOH/CdSe NCs, revealing that P3HT-M-COOH is more effective for nucleation and growth of nanocrystals as the polymer matrix. It was found in TEM images that there is …
WebP3HT (HO/HOP3HT) was synthesized using Grignard metathesis (GRIM) polymerization, which was reported in the literature [7,14]. In this study, commercial Hemin with two -COOH groups provides convenient conditions of esterification with -OH group terminated P3HT, while the reaction of -COOH with -OH WebLarge hysteresis in bilayer P3HT–TiO 2 devices indicates the presence of charge traps at the interface, unlike in P3HT-COOH–TiO 2 devices. The results provide insights into …
