Polymer solar cells fabricated with 4,8-bis(2-ethylhexyloxy)benzo[1,2-b:4,5-b′]dithiophene and alkyl-substituted thiophene-3-carboxylate-containing conjugated polymers: Effect of alkyl side-chain in thiophene-3-carboxylate monomer on the device performance |
| 초록 |
We have synthesized a series of copolymer bearing 4,8-bis(2-ethylhexyloxy)benzo[1,2-b:4,5-b′]dithiophene and the thiophene-3-carboxylate(TC) unit, and investigated the effect of alkyl side chain in the TC unit on the PV device performances. Also, we systematically studied the effect of alkyl side-chain in TC unit of these copolymers on the optical properties, film morphology, carrier mobility in organic thin film transistor (OTFT), as well as on the photovoltaic performance. These results provide useful information on how to control the JSC, VOC and PCE value of OPV devices, based-on the structural variation in copolymers containing TC unit. |
