Abstract

Flexible dye sensitized solar cells (DSSCs) possess multiple advantages with wide application and good commercialisation potential. However, the low conversion efficiency of the technology from poor charge transfer and interparticle contact has limited their utilisation. Thus, the research aims to enhance the performance of flexible plastic-based titanium dioxide (TiO2) film via the formation of TiO2-bismuth (Bi) ink for screen-printing of DSSC photoanode film. The implementation of Bi nanoparticles as sintering aid has managed to improve the interparticle contact in the photoanode film with neck formation at the TiO2-Bi interface. This phenomenon has also led to the lowering of resistance values by 57 - 65% with charge transfer resistance of 11.72 kΩ.cm2 and series resistance of 38.28 kΩ.cm2 for the TiO2-Bi photoanode. The recombination reactions were also reduced with longer electron lifetime of 0.0036 ms and enhanced charge transfer. The research has managed to prepare TiO2-Bi ink that would be suitable for the fabrication of flexible DSSC photoanode film via screen printing. Hence, the outcome of the research could potentially lead to the development of highly efficient flexible low temperature DSSC and enhance their commercialisation potential.

Abstract

The integration of photovoltaic (PV) system in power system proved to be potential technology in terms of renewable energy sources. However, photovoltaic system has major drawback of rise in cell temperature, which results in low power production and reduced service life. To overcome the temperature rise in photovoltaic system, the addition of water cooling and phase change materials installed at rear side PV system termed as photovoltaic thermal (PVT) system has been adopted in this study. The organic phase change material (RT-42) having melting temperature of 42 ℃ and water cooling running at 0.45 litre per minute (LPM) under 440 W/m2 irradiation has been taken as input parameters. The photovoltaic system and water cooled photovoltaic system performance has been analysed by using real time solar simulator. Additionally, the PVT-PCM system is assessed by use of TRNSYS simulation. Finally, this study compares the thermal and electrical efficiency of PV, PVT, and PVT-PCM systems. The findings indicated that maximum temperature for PV cells in a PV system was 59 ℃. Water cooling alone reduces the temperature down to 49 ℃, whereas water cooling combined with phase change material (PVT-PCM) lowers it down to 36℃. Further, the heat gain of 189 watt and 191 watt was achieved for PVT and PVT-PCM system. Additionally, the PV, PVT, and PVT-PCM systems achieved electrical efficiencies of 6.1%, 7%, and 9.5%, correspondingly.
