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 enhancing interfacial interactions between organic and inorganic materials using modifiers such as –COOH, for the rational design of efficient hybrid solar cells. WebDec 15, 2014 · The results show that only P3HT–OH, P3HT–NH 2, and P3HT–N(CH 3) 2 had estimates of E b lower than that of P3HT; at the same time, these derivatives were those …

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). WebSep 15, 2024 · Carboxyl end-functionalized poly (3-hexylthiophene) (P3HT-COOH) was grafted chemically with CdSe nanocrystals (NCs) by a phosphine-free method. The particle quality of P3HT-COOH/CdSe... WebFeb 1, 2008 · The F-SWCNTs has the pending carboxylic acid group (COOH). The PPy nanowires and bulky P3HT film were electrochemically polymerized based on the Al 2 O 3 nanoporous template and on the ITO glass, respectively, by using the F-SWCNTs as a dopant in electrolyte.
