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.

<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>
