제목 The Decrease of Interfacial Resistance by Inserting Triethylene Glycol based-Electrolyte as Interlayer in Organic Solar Cells
초록 The efficiency of devices is essential prerequisite for the energy industry. For high efficiency, it is important to decrease the interfacial resistance of the device composed of multi-layers. This can be easily achieved by inserting new electrolyte between the photoactive layer and electrode. We designed new electrolyte, named 2,2’-(ethane-1,2-diylbis(oxy))bis(N,N,N-trimethylethananminium) benzenesulfonate (TEG-2OTs), inserted as a thin layer. The result obviously showed the correlation between device efficiency and the decreasing of a Schottky barrier, where the Schottky barrier was induced from the difference between acceptor material’s LUMO and electrode (the difference without electrolyte 0.34, with eletrolyte 0.01). The decreasing of the Schottky barrier originated from the induced-dipole at the cathode interface from the electrolyte which lead to the well matched efficiency of the devices (PCEs of 7.48% and 7.78%, respectively).
