“…Along with basic electron transfer processes in DSSC prospects of a state-of-art device based on dye adsorbed on TiO 2 and I -/I 3in the form of redox pairs electrolyte is shown in Figure 1(a). On illumination, an electron photo generated by dye molecules as like in photosynthesis [19]. By photon (hυ) absorption a dye molecule is excited whereas electron is excited from HOMO into LUMO subsequently, the free electron is injected into the TiO 2 conduction band and left the oxidized dye molecule.…”

Dye-Sensitized Solar Cells (DSSCs) are prominent alternative devices to conventional p-n junction silicon based solar cells because of their low fabrication cost and high power conversion efficiency, good cost/efficiency ratio. In the present work, DSSC devices were made-up with fluorine doped tin oxide (FTO) glass substrate, a TiO2 compact layer was deposited on FTO, Ruthenium(II) dye (N719), an iodide - triiodide electrolyte and a platinum (Pt) counter electrode. Photo anode with thin film layers of TiO2 and Pt counter electrode (photo-cathode) were prepared. Field emission electron microscope (FESEM) was employed to investigate the surface morphology of TiO2 layers. The DSSC device efficiency was evaluated by J-V characteristics. Fabricated devices were exhibited high power conversion efficiencies. The electrochemical impedance characteristics were analyzed by fitting the experimental results to the corresponding electrical equivalent circuit simulated data.

DSSC using natural dyes extracted from bioactive components of red dragon fruit peel wastes were studied to determine the power conversion efficiency. Natural dyes were extracted by maceration method. Maceration is the soaking of fine powder from red dragon fruit peel for 24 hours in distilled water mixed with 10% citric acid with three variations of the material's weight ratio to the solvent, namely 1:4, 1:6 and 1:8. Materials were characterized by several tools such as SEM equipped with EDS, UV-Vis Spectrophotometry, and FTIR. The SEM analysis results with EDS showed that the TiO2 thin layer had mesoporous morphology and showed Ti and O without other impurities with a composition of 73.79% oxygen (O) and 26.21% titanium (Ti). The results of UV-Vis characterization of the absorbance spectrum showed that there was absorption in the visible area, and the three samples of the dye solution had different absorbance power, photon energy, and absorption coefficient (α). FTIR analysis confirms that the sample shows a hydroxyl group, the building block for the anthocyanin structure. DSSC parameters were characterized using a solar simulator with 500 W/m 2 lighting. The best performance is obtained at a ratio of 1:8 with Voc = 0.47 V, Jsc = 23.46 µAcm-2 , Fill Factor = 0.480 and efficiency 0.029%

Dye-sensitized solar cells (DSSCs) have aroused intense attention over the past three decades owing to their low cost, inexpensive raw materials, simple fabrication process, and employment of eco-friendly materials. Recently, to take advantage of their lower electrical resistance, excellent electrocatalytic operation, mechanical integrity, low cost, and flexibility, carbon nanotubes CNTs have been incorporated into DSSCs with a view to improve the efficiency further. CNT can be used in the anode, electrolyte, and counter electrode. The incorporation of CNTs into the anode’s semiconductor material decreases the host material’s resistance and increases thermal conductivity, electrical conductivity, mechanical strength, and durability. CNTs in ionic liquids have been investigated as a potential alternative for traditional liquid electrolytes for DSSC application because of low viscosity, low vapor pressure, high diffusion coefficient, high electrochemical, and thermal stability. CNT based counter electrode has attracted considerable interest because of its fast electron transfer kinetics and large surface area. This book chapter provides an insight into the fabrication of DSSCs by incorporating CNT and its effects on cell conversion efficiencies.
