High Interaction

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; U1and 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 μm down to 0.15 μm. 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.

Pada penelitian ini dilakukan sintesis nanopartikel TiO2 menggunakan metode sol-gel dengan pelarut air. Pada proses sintesis ditambahkan kitosan dengan konsentrasi 0; 2,5; 5; dan 10% v/v. TiO2hasil sintesis kemudian dikarakterisasi dengan menggunakan SEM, XRD, dan BET  untuk mengetahui morfologi,  struktur kristal, dan karakteristik pori. Selain itu keempat variasi TiO2diaplikasikan sebagai foto elektroda DSSC. Karakterisasi DSSC dilakukan dengan menggunakan solar simulator AM 1,5 untuk mengetahui karakteristik I-V DSSC. Hasil karakterisasi menunjukkan penambahan kitosan pada konsentrasi rendah (2,5% v/v) mengurangi fasa anatase pada kristal  TiO2dan cenderung memperbesar ukuran kristalit. Penambahan kitosan melebihi 5% meningkatkan fasa anatase dan memperkecil ukuran kristalit. Konsentrasi kitosan 2,5% memperkecil luas permukaan spesifik partikel dan volume total pori. Peningkatan konsentrasi kitosan memberi hasil sebaliknya. Performa DSSC terbaik didapat pada TiO2 dengan konsentrasi kitosan 2,5% saat sintesis, dengan Voc = 0,58 V, Jsc = 0,74 mA/cm , dan η = 0,51%.Kata kunci: titanium dioksida, Dye Sensitized Solar Cell, kitosan
