Abstract

The latest generation of solar cell that utilizes dye from plants as a photosensitizer is Dye-Sensitized Solar Cell (DSSC). The dye from Solanum melongena L. is one of the potential photosensitizers due to its chemical and physical characteristics.  This study aims to determine these characteristics as well as its efficiency value in DSSC. The dye was obtained by ultrasonic extraction in 1% HCl methanol solution. The crude extract of dye was treated in acid and basic condition and then separated by vacuum gravitation chromatography in a way that the polarity was increased. The results were a variety of dyes according to their polarity. The dye then applied in DSSC as the photosensitizers. The highest conversion value was 0.0211%, performed by the dye in pH 8 solution. The characteristic of this extract was identified by UV-Vis, FTIR, and GC-MS. All the spectral data indicated that the main component which responsible for this efficiency was pelargonidin.

Abstract

There was research on Dye Sensitized Solar Cell to determine the effect of concentration Henna (Lawsonia inermis L.) leaves pigments on the efficiency of DSSC. The solar cell is made with a sandwich structure, the dye used is made in three variations of concentration is concentration of 10%, 20% and 30%. TiO2 deposition on ITO glass made using the method of doctor blade with a cell area of 2.25 cm2 for 24 hours of immersion in the dye. Based on the results of measurements of IV by using a source of light, DSSC efficiency for dye obtained with a concentration of 30% which is 0.003366667%, to dye with a concentration of 20% is 0.0033264% and to dye with a concentration of 10% which is 0.000312%. This research can be concluded that the higher the concentration of dye used, the higher the efficiency of DSSC generated.
