| 제목 | ITO free organic solar cells with TiO2/Au grid – PEDOT:PTS hybrid electrode |
| 초록 | Transparent conductive oxides (TCO) are widely used in thin film optoelectronic devices for transmittance and resistance. Recently TCO based on In2O3, ZnO or SnO2 are commoly used. Among them, Indium-tin oxide (ITO) is the most important single layer transparent conductor. But there are technical and economic problems for a large scale fabrication of flexible devices. Recently, Metal-conjugated polymer hybrid structure has been actively researched to replace of ITO because the hybrid structure can produce transparent and low resistance. In this study, We fabricated a hybrid electrode by developing Au grid and tosylate doped poly(3,4-ethylenedioxythiophene: p-toluene sulfonate) (PEDOT:PTS) connection path with optimized Au grid aperture ratio. Au grid-PEDOT:PTS was deposited on the TiO2 which remarkably increased the transmittance. Organic solar cells fabricated on the TiO2/Au grid-PEDOT:PTS hybrid electrode showed a power conversion efficiency of 3.88%, comparable to that of ITO-based organic solar cell (3.91%). The TiO2/Au grid-PEDOT:PTS hybrid electrode shown to be promising replacement of ITO for use in low-cost and flexible optoelectronic devices. |
