Carbon quantum dot tailored counter electrode for 7.01%-rear efficiency in a bifacial dye-sensitized solar cell†
Abstract
We present here a carbon quantum dot (CQD) tailored counter electrode (CE) for a bifacial dye-sensitized solar cell (DSSC). Arising from wide spectral absorption, high optical transmission and the electron-enriched surface of the CE, the final bifacial DSSC device yields front and rear efficiencies of 9.08% and 7.01%, respectively.
