Effect of alkyl chain length in the Organic Electrolytes Based on Bipyridine as the Electron trasnporting layer on the Photovoltaic Properties |
| 초록 |
For high-efficiency organic solar cells, it is a required condition that photogenerated electrons move smoothly to the cathode. This can be achieved by introducing electrolytes into the cathode buffer layer (CBL). Using structural flexibility of organic electrolytes, we investigated the alkyl chain length’s effect about the solar cell efficiency based on fixed core structure, alkyl-quaternized bipyridine with tosylate. The organic electrolytes were named V-C4-OTs, V-C6-OTs, and V-C12-OTs, respectively. Power conversion efficiency (PCE) and incident photon-to-electron conversion efficiency (IPCE) were investigated with the device structure of ITO/ZnO/CBL/Aactive/MoO3/Ag. Work function was also investigated using Kelvin probe microscopy (KPM) measurements. The improved PCE and IPCE were induced by enhancement of the photogenerated current density, which be matched with decrease of a Schottky barrier well. |
