Sensitized TiO2 nanospheres with uniform diameter of ca. 100 nm were successfully synthesized by a hydrothermal method using urea as templates and subsequently employed as robust visible-light photocatalysts. The photocatalytic activities of the sensitized TiO2 nanospheres evaluated by photodegrading methyl orange (MO) were recorded, giving the best photocatalytic performance for the sample synthesized at 110°C for 36 h. The photocatalytic mechanisms of the sensitized TiO2 nanospheres were attributed to the reduction of bandgap energies and the sensitizing effect of melon. The resultant melon acted as a sensitizer to absorb visible light and induced electrons which participated in the photodegradation of MO molecules. The new concept was helpful to guide the synthesis of robust photocatalysts, dye-sensitized solar cells, or hybrid solar cells, and the results suggested that the sensitized TiO2 nanospheres were very promising for enhancing the visible-light photocatalytic activity of TiO2 photocatalysts.

For the first time in dye-sensitized solar cell (DSSC) technology, a di-carbazole-based dye was synthesized and evaluated for its usage as a potential sensitizer for the development of wavelength selective semi-transparent DSSCs for greenhouses-oriented applications. The dye was designed to demonstrate a blue light absorption, allowing a high transmittance in the red region of the visible light, even after its adsorption on the anode semiconductor, which is the most important one for the photosynthetic action of the plants. The application of the new dye to DSSCs was examined using either a high-performance iodide-based electrolyte or a highly transparent iodine-free electrolyte to determine a good balance between electric power generation and device transparency. The spectral engineered DSSCs demonstrated quite promising characteristics, providing a high external quantum efficiency (higher than 70%) in the whole blue–green region of the visible light, while allowing high transparency (up to 55%) in the red region, where the second peak in the absorbance spectrum of chlorophyll is located. Finally, the derived results were discussed under the consideration of important metrics for this niche application, including the transparency of the solar cells in the region of photosynthetic active radiation and the attained crop growth factor. The present work constitutes one of the few comprehensive studies carried out up to now in the direction of the development of 3rd generation “agrivoltaics” for their possible integration as cladding materials in energy-autonomous greenhouses.

It has been successfully identified and characterized by dye Melinjo peel (Gnetum gnemon) as an active material for Dye Sensitized Solar Cells (DSSC). The sample is formed in the structure of a working pair of electrode sandwiches and opposing electrodes. The dye extraction process (Dye) of the melinjo was stirred for 1 hour and then left to stand for 24 hours but there were only differences in how to doping dye into TiO2.Dye-sensitized solar cell (DSSC) is one of the photochemical electrical cells consisting of a photoelectrode, dye, electrolyte, and counter electrode. The purpose of using dyes in the DSSC is to extend the absorption spectrum to visible light because visible light has about 96% energy from sunlight. This article presents some experimental data on the nature of absorbance and the conductivity of natural dyes extracted from the plant as an application in the DSSC. Absorbance test using Spectrophotometer UV Visible 1601 PC and electrical properties test using Elkahfi 100 / Meter I-V. DSSC fabrication has been done using dye extract of melinjo (Gnetum gnemon) with a variety of immersion technique of drops and soak. The results show that natural dyes from natural material extraction have an absorbance spectrum of 380-520 nm range and the greatest conductivity is owned by melinjo (Gnetum gnemon). From the results of the test using AM Simulator 1.5G (100 mW / cm2) diesel simulator, it was found that the volume of TiO2 precursors affected the performance of DSSC solar cells and the overall conversion efficiency was 0.03% for the melinjo (Gnetum gnemon) dye by drops technique and 0.009% for the melinjo (Gnetum gnemon) dye by soak technique.
