Small-Molecule Electrolytes as a Cathode Buffer Layer for High Performances Polymer Solar Cells |
| 초록 |
Electrolytes as a cathode buffer layer (CBL) have affected a favorable interfacial dipole in polymer solar cells (PSCs). This can decrease the charge collection barrier at the cathode interface. New small molecular electrolytes (2EBr and 4PBr) were introduced as the CBL to generate the interface dipole and reduce the energy barrier. These electrolytes have an easy synthesis procedure and low processing costs. Furthermore, 2EBr and 4PBr have different ionic functionalities to tune the magnitude of the interfacial dipole. 2EBr has two benzyl trialkyl ammonium salts and 4PBr has a phenyl core with four benzyl triphenylphosphonium salts. The power conversion efficiencies (PCEs) of the devices based on 2EBr and 4PBr reached up to 9.56 % (Jsc = 19.7 mA/cm2 , Voc = 0.80 V, and FF = 61.1 %) and 10.63 % (Jsc = 20.2 mA/cm2 , Voc = 0.79 V, and FF = 66.6 %), respectively, which are superior than the PCE of the device based on pristine ZnO. |
