Abstract

Metallic glasses are alloys without long-range atomic arrangement, obtained from the atomic structure of its liquid state. The solid metallic glass is fabricated by rapidly quenching the liquid-state alloy, which allows it to circumvent crystal growth prior to solidification. The unique, metallic and amorphous properties of metallic glasses have opened up possibilities for various applications, for they exhibit superior mechanical and chemical stability than that of the conventional crystalline metals. In this research, metallic glass thin film sputtered onto polymeric film exhibited encouraging results in mechanical reversibility through bending tests. Subsequently, suitable sheet resistance and work functions for applications photovoltaic cells were attained through compositional tuning, which enabled fabrication of an electrode for OPV, with enhanced chemical stability than that of crystalline metal.
