Dye Sensitized

The dye sensitized solar cell (DSSC) is devices for converting solar energy to electricity. The gel polymer electrolyte is the main component in the cell. It is used for complexation with liquid electrolyte to generate iodide ions and support the ion transportation. The gel polymer electrolyte of poly(3-(trimethoxysilyl) propyl methacrylate) (PMPS) coat on the surfaces of natural rubber (NR) particles (PMPS-g-NR) was prepared by surface grafting emulsion polymerization method using the redox couple initiator, tetraethylenepentamine (TEPA) and cumenehydroperoxide (CHP). Then, this gel was treated by ozone at different treatment time (5 min, 10 min, 20 min, 25 min, and 30 min) and voltage of ozonolysis (0.7 kV, 1.5 kV, 2.4 kV, and 3.2 kV) on PMPS-g-NR (ozonolysed PMPS-g-NR) to obtain the optimum condition for generating the active species e.g. carbonyl or aldehyde structures. The synthesized materials were characterized by the degree of swelling (%DS), ionic conductivity, and solar cell efficiency, having red cabbage as dye sensitizer. By ozonolysis on PMPS-g-NR, the treatment condition of voltage at 3.2 kV and treatment time at 30 min showed the maximum %DS of 74.2, which is higher than that of PMPS-g-NR without ozonolysis of 65.5. The maximum ion conductivity of PMPS-g-NR and ozonolysed PMPS-g-NR at 2.4 kV and 20 min were 0.240 mS/cm and 0.775 mS/cm, respectively while their maximum solar cell efficiency was 6.738 m% and 10.340 m%, respectively.

Cast Technique

In this study, a freestanding thin film composed of lithium triflate (LiTf) salt (30-40 wt.%) and epoxidized-30% poly (methyl methacrylate)-grafted natural rubber (EMG30) (50, 54.6, 62.3 mol %) were prepared by a solvent cast technique. The EMG30 were found to increase the ionic conductivity of EMG30-LiTf by one order of magnitude compared to MG30-LiTf. The highest ionic conductivity achieved was 5.584 x10-3Scm-1at room temperature when 40 wt.% of LiTf salts were introduced into 62.3 mol % EMG30. The ionic conduction mechanisms in EMG30-LiTf electrolytes obey Arrhenius rule in which the ion transport in these materials is thermally assisted.
