Current electronic devices are fabricated mostly on glass or plastic films which are often hard to recycle. In this study, 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO) oxidized nano-cellulose (TOCN) film was explored as a green substrate candidate for next-generation electronic applications and its optical, surface and mechanical properties are presented in this report. Its prospective integration in the future dye-sensitized solar cells (DSSCs) was investigated by testing as one of the electrodes in a counter electrode-counter electrode configuration (CE-CE). The TOCN film was able to undergo the device sealing process at 220°C and 140 °C without any change in its color or dimension. The results highlight the potential of environmentally friendly and room temperature processed nano-fiber based films as an alternative substrate for bifacial devices.
