Highly efficient polymer solar cell modules fabricated by slot-die coating method |
| 초록 |
Slot-die coating is one of the promising methods for fabricating large-area polymer solar cells (PSCs) due to its compatibility with roll-to-roll printing and one-dimensional direct patterning. In this study, we investigated correlations between conformal film morphology of intermixed poly(3-hexylthiophene)(P3HT) and fullerene derivative [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) bulk-heterojunction(BHJ) material and universal control factors in slot-die coating method, such as shim length, substrate temperature, and coating speed. The observed correlation equation is better matched to the meniscus coating parameter equation rather than to the traditional high-viscosity extrusion slot-die coating parameter equation. By utilizing slot-die coating technology with the optimized governing factors obtained through this study, we demonstrated uniform large-area polymer solar cell modules with power conversion efficiency (PCE) of ~3% under Air Mass 1.5 condition. |
