Solvent effects on organic photovoltaics fabricated by a spray deposition method |
| 초록 |
In recent years, organic solar cells (OSCs) have reported power conversion efficiencies of 5% in this area. So, the OSCs have more possibilities move down the industrial road-map. As for film deposition method in the current activities of polymer based OSCs, the spin coating method is mainly used. But spin coating method is hard to fabricate large area and also difficult to use the roll-to-roll system. Deposition of organic films by a simple spray method is a promising method for the high-throughput roll-to-roll processing on large area that will drive the cost of OSCs down. We have already reported that performances of OSCs made by a spray deposition method. In this presentation, we will demonstrate various concentration effects of blend solutions on the changed of the morphologies in the sprayed films with various viscosities. And we will discuss about the effect of boiling point of solvents on optical, electrical properties of the sprayed OSCs. |
