Influence of Additive on The Performance of Energy Conversion Solar Cell

Dye-sensitized solar cell (DSSC) of natural dyes from local fruits which consist of the carbonyl and hydroxyl groups of anthocyanin molecule influences the performance of photosensitized effect due to high interaction on the surface of filler. The study is based on Titanium Dioxide, TiO2; U1 and U2 (without and with additive respectively), treated TiO2 with ultrasonic; U3 and U4 (without and with additive respectively). The additive for electrolyte, KI3 gives effects on the rate of electron injection to the oxidized dye sensitizer. Of treated TiO2 with ultrasonic was reduced the particle size agglomeration from 0.37 mu m down to 0.15 mu m. This contributes to a better 'sponge like' with high porosity in order to absorb more anchorage dye sensitizer. Treated U4 with addition of additive for electrolyte gives, Voc=0.74228 V, Isc=0.36 mA, FF=57.0124 gives 0.039% of efficiency.
