The I-V characteristics in the dark and under illumination highlight a photoactivity of the ZnO@N719 active layer with values of Jsc , Voc and fill factor comparable to the data reported in the literature. Natural dyes are environmentally and economically superior to ruthenium-based dyes because they are nontoxic and cheap. Also, its performance increased with increasing the sintering temperature of the semiconductor The absorption spectra of the extracts were performed in the spectral range from 400 nm to 750 nm. 2. The optical absorption of the extracted dyes diluted in ethanol or distilled water were measured using UV–Vis spectrophotometer. DSSC was prepared with TiO2 thin layer doped with active carbon; Natural dye was analyzed using UV-Vis and TiO2 was analyzed using X-ray diffractometer (XRD), meanwhile scanning electron microscope (SEM) was used to obtain the size of the crystal. Thus-far, several natural dyes have been utilized as sensitizers in DSSCs. Fig. Results showed that the conversion efficiency improved to 0.58%. of the phase transformation and the factors affecting its observation. The DSSC prepared using a combination of natural dyes (Raspberries, Hibiscus, Chlorophyll) by the ratio (1:1:1) as photo-sensitizer, showed the better photovoltaic performance compared with other single dyes. Ruthenium and osmium metal-organic complexes have been the most stable and effective dyes used for DSSCs [16, 17]. Thin layers of nanocrystalline were prepared on transparent fluorine doped tin oxide (FTO) conductive glass. We have employed several natural dyes for application in dye sensitized solar cells (DSSC). Different characterizations for the prepared natural dyes were conducted including UV-vis absorption, FTIR, and steady-state/time-resolved photoluminescence spectroscopy. phase transformation. However, Ru has several limitations due to high cost, rarity and complexity to be synthesized. The cell was tested in an own-constructed dark box. An early proof that carotenoids can function as photosensitizers in DSSCs was with 8′-apo-β-caroten-8′-oic acid bound to TiO 2 . Using natural dyes in solar cells is also advantageous due to their greener and lower cost. Natural dyes as photosensitizers for DSSCs are very attractive because they are of low cost, abundant in supply, and sustainable. For DSSCs applications, these mixtures co-sensitize the device to increase the global absorption using the widest wavelength range possible and thus maximizing the efficiency Works including the study of natural dye mixtures show different approaches [6, ...

This research on Dye-Sensitized Solar Cells (DSSCs) reengineering was carried out using TiO2 with natural dye (anthocyanin). The counter electrode is coated by a catalyst Pt (Platinum) to speed up the redox reaction with the electrolyte solution. Therefore, in order to overcome these problems, we chose to use natural pigments as sensitizing dye. There are three types of dye that have been studied, among others, chlorophyll, beta-carotene, and anthocyanin. We designed and synthesized alkyl-functionalized carbazole dyes (MK dyes) for use in DSSCs. Besides being used as a natural dye, chlorophyll can also be used as an alternative counter electrode. We propose a paper solar cell based on carbon nanotube (CNT)-composite papers. To fabricate this cell, we use dye-sensitized solar cells (DSCs) for generating power through the redox reaction of dyes in conjunction with CNT-composite papers, which are composite materials containing CNTs and pulp (raw paper material) that can be fabricated easily by using a method based on the Japanese washi papermaking technique.

In the extracts of natural fruit, leaves and flower chosen, the black rice extract performed the best photosensitized effect, which was due to the better interaction between the carbonyl and hydroxyl groups of anthocyanin molecule on black rice extract and the surface of TiO2 porous film. parameters such as short circuit current density Jsc, open circuit voltage Voc, fill factor FF, and overall by irradiation with halogen lamp of 20 Watt/220 Volt with intensity of 3.58 W/m2 at a distance of 20 cm. The wurtzite form of zinc oxide suffers from piezoelectricity and its energetic levels are very similar to those of the most used inorganic semiconductor employed in DSSCs, that is, TiO2 . Recent research is diverted to explore the potential of natural dyes in replacing the conventional dyes. Results concerning betalain pigments present in bougainvillea and beetroot extracts, and anthocyanins in eggplant extracts, analyzed by using UV-Vis spectrometry, are included. As an example of application, we report procedures intended to test and enhance the dye potential as a main component of dye-sensitized solar cells (DSSCs). The effectiveness of electron transfer was found to be related to the interaction between the chlorophyll dye and the TiO2 film surface. Then, the calculation of energy absorbed by natural dye used Equation 5. The characterization of the cell gives I-V characteristics with open circuit voltage of 192.60 mV, short circuit current of 27.45 μA, fill factor of 29.88 %, and energy efficiency of 0.196 %. The mallow cell shows a good fill factor of 55% and a noticeable photoelectric conversion efficiency of 0.215%. Ho Chang . The molecular dye is an essential component of the Dye sensitized solar cell (DSSC), and improvements in efficiency over the last 15 years have been achieved … Titanium dioxide (TiO 2) is one of the popular semiconductors used for DSSC since it is cheap, non-toxic, and possesses a large bandgap . Published under licence by IOP Publishing Ltd, The 2nd International Conference on Science (ICOS), IOP Conf. Keithley instrument test was carried out to find out I-V characteristics indicating that the highest efficiency occurred in DSSCs solar cell with 24-hour soaking with mangosteen peel 0.00047%.

Mixtures of several dyes with different absorption spectra are often prepared to obtain the maximum absorption within the visible and infra-red region. It was cleared, Two of the most known properties of ZnO were used to improve the performance of a dye-sensitized solar cell (DSSC) using a nanoadduct formed by zinc oxide and the well-known ruthenium dye N719. Due to the fact that these dyes are toxic, expen- sive, and difficult to synthesize, growing activities for using natural dyes have been reported [18–20]. The best performance is generated by mixed dye 1.91 x 10⁻³ % compared than those DSSC for dye extracted from Jatropha leaves or purple Chrysanthemum. Synthetic dyes as sensitizer in DSSC are efficient and durable but they are costlier, toxic and have the tendency to degrade. The use of dye from nature with its simple production process is very effective to reduce DSSC production cost. Since a DSC can generate electricity without using rare metals and can use various natural dyes [3][4][5], Nanocomposites Materials for Microwave Absorber Application, ZnO is introduced as an alternative to TiO2 in dye sensitized solar cells (DSSCs) due to its band gap similar to TiO2, higher electron mobility, and flexible procedures of preparations. Thus, in exchange to metal complex Ru dyes, current researches are focusing on natural dyes that are extracted from plants. They showed up to 0.12 % conversion efficiency values. Cells using henna and mallow as dyes present less degradation with time in the photoelectric characteristics. From Table 1, the lowest photon energy (eV) and As for the resulting curren, (Max). The influence of the extraction solvent and method, and of parameters such as pH are analyzed.
