Abstract

The natural dye extracted from Amaranthus dye and Carica Papaya dye which has been prepared in ethanol solution as a sensitizer on DSSC. The Spin coating method is used so that the deposition on TiO2 gets a homogeneous thin layer on the active area of the FTO substrate. The dye solution was tested for characterization using the Elkahfi I-V Meter and UV-Vis 1601 while the FTO structure substrate that had been prepared as a sandwich was tested using Keithley I-V type 2602A. The result of absorbance of dye is at a wavelength of 400 nm - 800 nm and there is also a shift in wavelength and peak absorption of the dye. The greatest efficiency was obtained from chlorophyll amaranthus which is 0.730% while chlorophyll Carica papaya obtained an efficiency of 0.432%. In the combination of Amaranthus dye and Carica papaya dye, the efficiency was 0.526%. High efficiency on TiO2 electrodes shows good performance on Dye-sensitized solar cells.

Abstract

The utilization of Indigo tinctoria as a DSSC sensitizer has been done to study the effect of I. tinctoria’s immersion time on DSSC efficiency. One of the most essential components in DSSC is a sensitizer or dye. In this work, the dye has been used in DSSC is the natural indigo dye from I. tinctoria leaves. The extraction was done by dissolving 50 grams of I. tinctoria leaves in 500 mililiters aquades and soaking in various time: 12, 24, 36, and 48 hours. The optical properties of dye solution was characterized by UV-Vis spectrophotometer and the current-voltage of DSSC was characterized by Keithley I-V Meter. The highest absorbance is 2.7 of 48h dye solution, but the best efficiency of DSSC is 5.39 x 10-3 % that owned 24 h cell.

Abstract

 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. TiO2 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 TiO2 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%.

Abstract

Application of on-grid PLTS on the effort of catfish enlargement aims to reduce the cost for the fulfillment of electrical energy, increase knowledge and train the skills to assemble PLTS on grid. Farmers catfish use electrical energy to power the water pump. PLTS on grid enables saving on electricity costs. The use of on-grid PLTS does not require an electric storage battery. The overproduction of electricity from PLTS allows it to be sold to PLN. If there is a shortage of electricity, then electricity is purchased from PLN. Public knowledge about PLTS can be introduced in theory and practice of PLTS installation scale 2000 WP (watt peak). The use of 2000 WP can produce 9.2 KWH / day in sunny conditions.e
