High efficiency organic photovoltaic devices with inkjet printed-all-polymer layers |
| 초록 |
In this study, we report efficient methods for fabrication of polymer solar cells by inkjet printing. We prepared polymer solar cell devices with hole transporting layer of poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate)(PEDOT:PSS) and photo-active layer of poly(3-hexylthiophene)(P3HT):[6,6]-phenyl C61-butyric acid methyl ester (PCBM) mixture (1:0.7) on the ITO by inkjet printing. In order to find the optimum fabrication conditions for both layers, we have investigated inkjet printing parameters such as drop formation behaviors, solvent mixtures and substrate temperatures of polymer inks. The controlled printing parameters leaded to obtain pin-hole free surface films achieving power conversion efficiency over the 3.5% for photovoltaic devices with inkjet printed-all-polymer layers under illumination, 100mW/cm2 at AM1.5 simulated light. |
