Organic π-conjugated chromophore with furan spacer for solution-processed small molecule organic solar cells |
| 초록 |
A novel thiazolo[5,4-d]thiazole-core organic chromophore (RFTzR) was synthesized and applied as electron-donor material for solution-processed small molecule organic solar cells (SMOSCs). The molecule has showed a good thermal stability of ＞350 with self-assembly behavior. RFTzR exhibited good oxidation stability with HOMO and LUMO energy levels of -5.36 eV and -3.14 eV, respectively. The blended thin film of RFTzR:PC60BM (2:1, w/w) exhibits homogeneous and smooth morphology of low surface roughness (Rrms=1.94 nm) with nanoscale phase separation in chlorobenzene solvent. The fabricated cells of RFTzR (donor) and PC60BM (acceptor) as photoactive materials showed relatively smooth thin film morphology of devices which gives a maximum PCE of 2.72% (RFTzR:PC60BM, 2:1, w/w) optimized ratio with good open-circuit voltage of 0.756 V and high photocurrent density of 10.13 mA/cm2. The present study makes a way for the furan-bridged organic chromophores in small molecule organic solar cells. |
