Dye-sensitized solar cells (DSSCs) have attracted many researchers because it has potential to supplement and compete with other solar cell technologies like Silicon (Si) and Cadmium Telluride (CdTe). The fabrication of DSSCs requires a photo electrode and a counter electrode of transparent and conducting nature. The commercial DSSCs uses electrodes of fluorine doped tin oxide (FTO) glass substrates. These electrodes are expensive and hence, possible alternative materials that are cheaper and that would provide better performance under similar environmental condition should be explored. In this paper, titanium (Ti)-coated glass substrates were prepared and then used to prepare electrodes for fabricating DSSCs. Similarly, DSSCs were fabricated using electrodes of conventional FTO-coated glass substrates. Performance characteristics like cell efficiency (η%), fill-factor (FF), short circuit current density (JSC) and open circuit voltage (VOC) of both fabricated DSSCs were obtained using their respective J-V characteristic curves under similar illumination of 100 mW/cm2 and with comparable transmittance under the visible transmission spectrum of 300-850 nm. The obtained results showed that DSSCs prepared using electrodes of FTO coated glass substrates have 1.557 times better cell efficiency and 2.172 times better fill factor than that of DSSCs fabricated using electrodes of Ti-coated glass substrates.

Transparent conductive oxide (TCO) is one of the important components in dye-sensitized solar cells. The main requirements of TCO for dye-sensitized solar cells are having a low electrical resistance and a high light transmittance. This study focuses on the synthesis of fluorine-doped tin oxide including its optimization. The synthesis of fluorine-doped tin oxide has been conducted under spray pyrolysis technique in which a precursor solution of SnCl2:F having concentration of 0.3, 0.5, 0.7, and 0.9 M. The spray pyrolysis was performed using a nebulizer with deposition time of 10 min. The glass substrate was heated at a temperature of 400, 450, and 500°C prior to deposition. The fluorine doped tin oxide was then measured the electrical resistivity for each area of ​​1 cm². Therefore, the mean and distribution of electrical resistivity of fluorine-doped tin oxide with an area of ​​10 x 10 cm then were predicted. In addition, the morphology and transmittance of fluorine-doped tin oxide are also examined. The optimization of the synthesis process of fluorine-doped tin oxide using spray pyrolysis was obtained at a concentration of 0.7 M with a sintering temperature of 400°C. The best fluorine-doped tin oxide has been also fabricated into the dye-sensitized solar cell and the performance has been studied.

ABSTRACTTo provide a counter electrode with lower-cost and simple production method for dye-sensitized solar cells (DSSCs), we developed polyaniline/graphene nanoplatelet/multi-walled carbon nanotube (PANi/GNP/MWCNT) composite films growing on glass substrates by using chemical/electrochemical deposition method and on fluorine-doped tin oxide (FTO)/glass substrates by using electrochemical deposition method respectively. A proper weight ratio of PANi/GNP/MWCNT (1/0.0030/0.0045) composite film depositing on FTO substrate as counter electrode with sheet resistance of 8.25±0.13 Ω/sq for DSSCs yielded power conversion efficiency (PCE) up to 7.45±0.08%, which has potential to replace the conventional Pt cell (7.62±0.07%). In addition, we also fabricated the DSSCs composed of a proper weight ratio of PANi/GNP/MWCNTs (1/0.0045/0.0060) composite film depositing on glass substrate as counter electrode. The sheet resistance of resulting composite film was 59.34±12.34 Ω/sq. These solar cells with FTO-free counter electrode exhibited a PCE of 2.90±0.09%.
