Quasi-solid-state composite electrolytes with Al2O3 and ZnO nanofillers for dye-sensitized solar cells

In the literature, so far, in-situ chemical cross-linking methods have been utilized for the preparation of Al2O3 or ZnO-composite polymer gel electrolytes (PGEs). Such PGEs have shown poor performance in quasi-solid-state dye-sensitized solar cells (QS-DSSCs) under one-sun conditions. Moreover, the QS-DSSCs using ZnO-PGEs had higher open-circuit voltages (Voc) than the cell using Al2O3-PGEs; but their conversion efficiencies are much lower. To...
