CuAlO<inf>2</inf> powder dispersed in composite gel electrolyte for application in quasi-solid state dye-sensitized solar cells

© 2015 Elsevier Ltd. All rights reserved. The use of delafossite CuAlO<inf>2</inf> (CAO) powder as an additive in composite gel electrolyte (CGE) of the quasi-solid state dye-sensitized solar cell (DSSC) is first reported. In order to achieve an improvement of power conversion and long-t...

In order to achieve an improvement of power conversion and long-term performance of the quasi-solid state DSSC, different contents of CAO powder containing in CGE, a mixture of polyethylene glycol (PEG), iodide/tri-iodide (I<sup>-</sup>/I<inf>3</inf><sup>-</sup>) liquid electrolyte (LE) and 4-tertbutylpyridine (4-tBP), were used in the present study.
