Fabrication of dye natural as a photosensitizers in dye-sensitized solar cells (DSSC)

Abstract

<p class="Abstract">The purpose of this study was to obtain optical properties (absorption spectrum) and electrical properties (photoconductivity) of organic dyes in DSSC performance. optical and electrical properties were tested by using UV-Visible Spectrophotometer and Elkahfi 1601 PC 100 / IV meter, respectively, while Keithley Type 2600A is used for the characterization of DSSC. This study is a great base to explore and investigate the development of DSSC solar cells using natural dyes (organic). Spectra optimal absorption and photoconductivity produced by natural dyes (organic). The results of this study indicate that the absorption spectrum of natural dyes (organic) in the range of 300-500 nm. electrical characteristics (I-V) of the increase in linear dye under illumination. I-V characteristics of DSSC from organically produced natural dyes to color the biggest-mangosteen obtained Voc of 565 mV; JSC = 1.52 A / m2; FF = 0.12; and η_ef is approximately 0.09%, respectively,. The conclusion of this study, natural dyes (organic) can be an attractive alternative as a dye.</p>

POLY ORGANIC POLYMER (3-HEXYLTHIOPHENE) P3HT as LIGHT SENSITIVITY in PROTOTYPE DYE-SENSITIZED SOLAR CELLS (DSSC)

“…Dye Sensitized Solar Cell was first discovered by Gratzel and Brian O'Regen in 1991 at Ecole Polytechnique Federale De Lausanne, Switzerland. Dye Sensitized Solar Cell (DSSC) is a photoelectrochemical solar cell that uses electrolytes as a transport medium [2] Solar cells or commonly called photovoltaic cells are devices that can convert solar radiation into electrical energy [8]. The DSSC is composed of a working electrode consisting of Flourine Tin Oxide (FTO) glass, Titanium Dioxide (TiO2), natural dyes, an electrolyte consisting of a redox pair I¯ / I³¯ and a counter electrode consisting of graphite or carbon.…”

“…Energy is an essential requirement in fulfilling all life necessities globally, so that energy needs are increasing daily [1]. Therefore, the search for alternative energy sources that can be renewable (renewable), cheap, and environmentally friendly is a demand that cannot be postponed any longer today due to the significant reduction in fossil fuel reserves in recent years [2], as well as the effect of greenhouse and global warming caused during the process of their use. Therefore, the problem of increasing national energy consumption must resolve immediately.…”
