<p align="center"> </p><p>Senditized Dye Solar Cells (DSSC) consist of photoelectrode, dye, electrolyte and counter electrode which is one of the photochemical electric cells. In this article will discuss the influence of the thickness of the electrode on the electrical properties. Electrodes made by screen printing method. Screen by type T-49. TiO<sub>2</sub> deposited on the FTO variation of the number of layers to obtain a thickness of 1, 2, 3 and 4. DSSC tested thickness by Screen Electron Microscopy (SEM), absorbance test by UV Visible Lambda 25 and characterization of current and voltage test by Keithley Measurenment 2602A. The test results showed the thickness of the TiO<sub>2</sub> electrode thickness (1.5 ± 0.2) μm, (2.9 ± 0.5) μm, (3.5 ± 0.6) μm, and (4.5 ± 0.8 ) μm. Based on the test results absorbance maximum value contained in thickness (4.5 ± 0.8) μm having a dye adsorbed at most and have the highest efficiency  2.41%.</p><p> </p>

Printing Method

Copper-doped tin oxide nanopowder has been synthesized via the hydrothermal route, in which pure metallic Sn, diluted nitric acid solution and Cu(NO3)2 are used as the starting materials. The hydrothermal treatment at about 200°C for 10 h results in rutile crystalline SnO2 particles with a narrow size distribution typically in the range of 3~6 nm. The average crystallite size of 5 wt% CuO-doped SnO2 particles remains smaller than 12.5 nm even after annealing at 800°C. The evaluation of the sensitive properties of the synthesized powder with various amount of CuO doping is conducted on the thick-film samples fabricated by screen-printing method. The high sensitivity toward H2S as shown by the sensor test results show the possibility of using this material for gas sensor fabrication.

Natural dyes extracted from black rice are used as sensitizer for dye sensitized solar cell. The anthocyanin extracted with various pH in acidic and neutral coditions. Preparation of fotolectrode TiO2 film using doctor blade method and resulting average grain size 33,9 nm using X-Ray Diffractometer. Characterization of morphology and cross-section film TiO2 is confirmed by Scanning Electron microscopy (SEM). Optical absorption using UV-Visible Spectroscopy to obtain spectrum absorbance of anthocyanin in various pH. The current-voltage (J-V) characterization shows the performance DSSC have a match relation to the optical absorption. The best absorption of anthocyanin obtained at pH 6 as well as conversion efficiency reaches 2.26% at this pH condition.

High performances of Hybrid Dye Sensitized Solar Cell are necessary in absorbing more sunlight and needed renewable energy source to replace depleted fossil fuels via green energy. Hybrid DSSC is another promising option towards green energy to explore. This research aims, i) to study conjugated chlorophyll in order to increase charge carrier in molecule structure besides, increase the absorption spectrum via conjugating process with the addition of different amount Ferric (III) Chloride (FeCl3) acting as catalyst and, ii) to determine the effect of FeCl3 on the performance of conjugated dye as sensitizers in Hybrid DSSC. The conjugated chlorophyll shows a using UV-Visible analysis corresponding to conjugated chlorophyll absorbed in high region called red shifted which the maximum absorption obtain at a wavelength of 360nm and 311nm. Fourier Transform Infra-Red characterization of the an existing Fe-O bond appears at 430 cm-1 to 445 cm-1 and C≡C bond at 2244 cm-1 to 2260 cm-1. 10% FeCl3 in conjugated chlorophyll produce huge impact to electrical conductivity and efficiency with the highest value; 0.114 S/cm and 0.14%; respectively. Thus, it can be conclude that 10% FeCl3 of conjugated chlorophyll – Imperata cylindrica (iCHLO-IC) was suitable to be used for the next generation of hybrid DSSC.

Practical Forming

Bi-based glass pastes were prepared in the mixed organic solvents (α-terpineol and texanol) with different kinds and concentrations of organic dispersant such as fish oil , phosphate ester and poly methyl methacrylate (PMMA). The rheological stability of glass pastes was characterized by using a rheometer and adsorption behavior of organic additives for the glass powders was carried out by using a thermal gravimetric analyzer (TGA).The Bi-based glass pastes exhibited the most stable rheological behavior at an addition of phosphate ester of 0.5 in mass %, due to the steric repulsive force acting on the surface of glass powers with adsorbing the organic additives. This study allowed significant delay of the sedimentation time and suppressed generation of micropores during practical forming process by a screen printing method.

Sensitized Solar Cells

Screen printing has been considered to be the simplest and quickest way to fabricate dye- sensitized solar cells (DSCs) modules for an assembly line. 20cm×10cm DSCs modules with W-type series connection and parallel connection were fabricated. The whole fabricating process was all operated by screen-printing except for the injection of electrolyte. The optimized TiO2 electrode thickness, sealant thickness and platinum counter electrode thickness were investigated. The modules showed a reliable performance.
