Surface Carbon Shell-Functionalized ZrO<sub>2</sub> as Nanofiller in Polymer Gel Electrolyte-Based Dye-Sensitized Solar Cells
We prepare dye-sensitized solar cells (DSSCs) fabricated with a poly (ethylene glycol) based polymer gel electrolytes (PGEs) incorporating surface carbon shell-functionalized ZrO<sub>2</sub> nanoparticles (ZrO<sub>2</sub>-C) as nanofillers (NFs). ZrO<sub>2</sub> a...

| description | We prepare dye-sensitized solar cells (DSSCs) fabricated with a poly (ethylene glycol) based polymer gel electrolytes (PGEs) incorporating surface carbon shell-functionalized ZrO<sub>2</sub> nanoparticles (ZrO<sub>2</sub>-C) as nanofillers (NFs). ZrO<sub>2</sub> are polymerized <i>via</i> atom transfer radical polymerization (ATRP) using poly (ethylene glycol) methyl ether methacrylate (POEM) as a scaffold to prepare the ZrO<sub>2</sub>-C through carbonization. The power conversion efficiency of DSSC with 12 wt% ZrO<sub>2</sub>-C/PGEs is 5.6%, exceeding that with PGEs (4.4%). The enhanced efficiency is attributed to Lewis acid-base interactions of ZrO<sub>2</sub>-C and poly (ethylene glycol), catalytic effect of the carbon shells of ZrO<sub>2</sub>-C, which results in reduced crystallinity, enhanced ion conductivity of electrolytes, decreased counterelectrode/electrolyte interfacial resistance, and improved charge transfer rate. These results demonstrate that ZrO<sub>2</sub>-C introduction to PGEs effectively improves the performance of DSSCs. |
