Abstract

Electrolyte is one of the crucial elements in dye sensitized solar cells (DSC) due to the reduction-oxidation reactions take place in this area and it has the function as the charge transfer medium. An electrolyte solution contains redox couple such as I-/I3 is filled up into a space between the photo-anodes and the counter electrode. Usually, the DSC employs a liquid electrolyte which using organic solution because easy preparation. But it has disadvantage, solvent evaporation occurs and this can decrease the cell performance. One of way to solve this problem is change liquid electrolyte to gel electrolyte. This paper describes fabrication of DSC based on gel electrolyte. Performance of the DSC is compared to the cell which using a liquid electrolyte. The result shows that the energy conversion efficiency of the solar cells based on gel electrolyte was lower than liquid electrolyte solar cell that is 1.51% and 2.23% respectively. Based on life time investigation obtained the performance of gel electrolyte solar cell is much stable than liquid electrolyte solar cell.

Abstract

The scale-up of dye-sensitized solar cell (DSSC) has been a big issue as the DSSC technology process progresses from laboratory scale to large area applications. Meanwhile, this type of solar cell has been of great interest among PV scientist and academics as it can be produced in lower-cost processes compared to the conventional solar cells which are mostly fabricated from silicon. The fabrication of DSSC prototypes with a relatively large active area of 9x9 cm2 are demonstrated in this paper. Large area of TiO2 surface has been shown to significantly increase the ISC, as well as VOC and Pmax. Nevertheless, deterioration of fill factor (FF) was observed as the result of the increase on series resistance with respect to the increase in the photoelectrode area.
