Simultaneous Enhancement of Efficiency and Air stability in Polymer Solar cell with modified PEDOT/PSS buffer layer |
| 초록 |
In most of the bulk heterojunction (BHJ) OSCs, poly(4-styrene sulfonate)-doped poly(3,4-ethylenedioxythiophene (PEDOT:PSS) is widely used as hole transport layers (HTL). However, PEDOT:PSS accelerates the degradation of OSCs due to its highly hygroscopic and acidic nature. To solve this problem, PEDOT/PSS was modified to have a resistance from water using polymeric additive. As a results, power conversion efficiency(PCE) increased from 2.516% to 2.917% by 16% and half-life times also increased around 2 times. The electrical and morphological properties of modified PEDOT/PSS was analyzed by X-ray photoelectron spectroscopy(XPS), Kelvin probe, 4-point probe meter and atomic force microscopy(AFM) respectively. This method is very simple on the production process and shows a lot of applicability in various organic electric device such as OPV, OLED, OTFT etc.. |
