Pencil graphite as a counter electrode for applications in DSSCs

Dye-sensitized solar cells (DSSCs) can be a promising alternative of conventional silicon-based photovoltaics due to facile manufacturing and low-material cost and ability to work even under low illumination condition. Here in, the counter electrode (CE)-based on pencil graphite material was prepared with the facile and cost-efficient method for DSSC applications. We evaluated the performance of this CE by measuring the power conversion efficiency of fabricated DSSC. The DSSC fabricated using pencil graphite counter electrode demonstrates nearly comparable efficiency over that of traditional Pt-electrode.
