1. Technology Overview
The present invention proposes a gel electrolyte based on polyacrylonitrile (PAN) for DSSC. The electrolyte comprises of PAN, ethylene carbonate (EC) and propylene carbonate (PC) as a plasticizer; characterised in that, the electrolyte further comprises 4- tert-Butylpyridine (TBP), tetrapropylammonium iodide salt (Pr4NI), lithium iodide salt (LiI), 1-butyl-3-methylimidazolium iodide (BMII) and iodine. It was found that the DSSC can achieve efficiency of 9 % with N3 ruthenium-based dye. The electrolyte have a composition of 8-10 wt.% PAN, 33-41 wt.% EC, 30-38 wt.% PC, 9-11 wt.% TBP, 3-5 wt.% Pr4NI, 3-5 wt.% LiI, 1-2 wt.% BMII and 1-2 wt.% iodine. The photoanode of the DSSC comprises a glass substrate, a fluorine-doped tin oxide layer adjacent to the substrate, a P90 titanium dioxide layer adjacent to the fluorine doped tin oxide layer, and a ruthenium sensitized P25 titanium dioxide layer adjacent to the P90 titanium dioxide layer. The counter electrode comprises a glass substrate, a fluorine doped tin oxide layer adjacent to the substrate and a platinum layer adjacent to the fluorine-doped tin oxide layer. The solar cell can be connected with fifteen same solar cells to form a solar panel. The solar panel is provided with the solar cells in a parallel pair of eight solar cells in series. A method to produce the gel polymer electrolyte based DSSC is also described.
