Abstract

Dye sensitized solar cell (DSSC) are photoelectrochemical based solar cells that involve the transfer of electrical charges from one phase to another. This research was carried out aimed at making DSSC (Dye Sensitized Solar Cell), Knowing the value of the conversion of solar energy into electrical energy and determining the value of the resulting efficiency. In this research, TiO2 degusa P-25 is coated with ITO glass by conductive part through doctor blande technique. Photon absorbent substances in this study used dye from tanned acid which was polymerized results characterization with FTIR on dyes has a strong absorption band at 1050 nm wavefroms indicating the presence of ether functional groups. In addition, when the DSSC circuit is illuminated by a 24 watt UV lamp it will produce electrical properties such as resistance and voltage as measured by a digital multimeter. Variation of inisiator and surfactant can influence the efficiency of the DSSC prodyced the highest efficiency is produced at a concentration of 0,5 M inisiator and 16 grams of surfactant mass which is 7,145 %.

Abstract

Dye Sensitized Solar Cell (DSSC) is a solar cell with a dye as an absorbent of photons from sunlight. Research related to DSSC is still ongoing to find DSSC components that produce high efficiency, but are easy and inexpensive to produce. Polymerization is a combined reaction of several monomers with certain rearrangements. The polymerized monomer is tannic acid which is an organic compound that has about 20 π-π * bonds. The tannic acid produced is then used as a dye in the DSSC circuit. Assembled DSSCs are tested for voltage and resistance using a digital multimeter. The polymerized dyes were characterized using UV-Vis, FTIR. The results of the UV-Vis analysis showed that the batochromic shift occurred in the polymerized dye. The batochromic effect will cause more photons to be converted into electrical energy. The FTIR spectrum is used to confirm the formation of poly-tannic acid. The efficiency of DSSC with polymerized dyes was higher than that of non-polymerized dyes, which was 8.9%
