dc.description.abstract | Polymeric electrodes are known for their intrinsically high mechanical stability, which suggests that fabrication of highly flexible photovoltaic devices is feasible through the implementation of these soft materials. However, the metallic electrodes that provide an electrical connection to these soft polymers often cause the polymeric electrodes to become mechanically unstable, degrading the overall performance of flexible photovoltaic devices under external stress. In this research, for the first time, aluminum-yttrium (AlY) amorphous metallic alloy thin film functions as a charge collecting electrode for poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) polymeric electrodes as part of a flexible organic solar cell. Unlike conventional metals, amorphous metals consist of atoms without a long-range ordered structure, endowing them with robust mechanical strength and flexibility. Optical and electrical analyses revealed that an amorphous AlY metal thin film on a PEDOT:PSS electrode withstands cyclic bending stresses without any mechanical failure. The incorporation of an amorphous metal electrode resulted in improved stability of the electrical parameters and efficiency under cyclic bending stresses when compared to organic photovoltaic devices with conventional crystalline metallic electrodes. © 2023 Elsevier B.V. | - |
