Background: Energy crisis is a vital issue worldwide and it will be increased tremendously in future. Alternative energy sources have been sought for the betterment of the future world. Solar energy is an alternative energy resource with plenty of opportunities. To make user- friendly and cheaper solar cells, dye-sensitized solar cells are tried to develop in this aspect. Objective: Single dye is not good enough to capture a wide range of solar light. The blending of different dyes is an alternative approach to harvest a wider range of solar lights on solar cells. Here, N719 and IR dyes were utilized to get UV-VIS and NIR ranges of solar lights in dye-sensitized solar cells. Methods: Dye-sensitized solar cells (DSSCs) were fabricated by using mixed dyes with various combinations of N719 (dye A) and IR dyes (dye B). The mixed dyes solutions were adsorbed on titanium dioxide (TiO2) and revealed significant light absorption & photosensitization compared with the individual dye solutions. The DSSCs fabricated with more percentage of IR dyes exhibited the best sensitization and broader spectrum. Results: The light absorption spectrum of the blended dyes solutions was confined peaks resultant of both N719 and IR dyes. The maximum efficiencies of 7.91% and 7.77% were obtained with 70% and 80% of IR dyes, respectively. Conclusion: Both N719 and IR mixed dyes solar cells were fabricated successfully for the first time. The relevant reasons behind the working of N719 and IR mixed dyes solar cells have been discussed. It was also noted that only IR dyes sensitized cells did not function under the simulated sunlight.

Dye-sensitized solar cells (DSSCs) have been developed as a promising photovoltaic cell type in recent decades because of their low cost, environmental friendliness, ease of fabrication, and suitability for a wide range of indoor and outdoor applications, especially under diverse shaded and low-light condition. They are typically composed of three main components: a transparent conducting oxide (TCO) substrate-based working electrode with wide-bandgap semiconductors and dye sensitizer molecules, an electrolytic mediator based on redox couple species, and a TCO-based counter electrode consisting of catalyst materials. The development of intrinsic and functional organic, inorganic, metal oxide, composite, and carbon-based materials has been intensively studied to enhance the efficiency of DSSCs. A simple and low-cost fabrication process that uses natural products is also considered essential for further large-scale production. In this article, we review the fabrication of various functional materials and their effects on DSSC performance.

Dye sensitized solar cells (DSC) are an attractive alternative to the conventional photovoltaic cell because of their low cost electricity production from solar radiation. The advantages of a DSC include the ability to generate power without emitting pollutants and requiring no fuel. While modeling of the physical and transport phenomena in DSC has been widely reported in the literature, a thorough analysis to quantitatively determine the optimal design and operating configuration in installation is lacking. The present study incorporates a model of the DSC coupled with a model to predict global irradiance on a terrestrial surface to analyze the hourly, daily, monthly and annual performance of a DSC installation over a wide range of design and operating parameters. Optimum design and operating parameters are derived from the analysis.

The preferred (002) orientation Zinc oxide ( ZnO ) nanocrystalline thin films have been deposited on ITO-coated glass substrates by means of sol-gel spin-coating technology and rapid thermal annealing for use in dye-sensitized solar cells (DSSC). The effects of annealing temperature (400 ~ 700 ° C ) on the microstructure and morphology of ZnO thin films were studied. With the increase of heating temperature from 400 °C to 700 °C, the grain size of ZnO thin films decreases from 80 to 10 nm. The decreases in grain size of ZnO thin films contributed to the improvement on the absorption of dye onto the films. The ITO/ZnO/RuL 2 (NCS) 2 electrodes with high absorption in the wide range containing visible light reveal that the nanoporous structure can adsorb easily the dye and can be expected in the application of DSSC.
