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.

Penelitian ini merupakan penelitian awal untuk mempelajari dan memahami proses pembuatan sel surya berbasis Dye Sensitized Solar Cell (DSSC) menggunakan Ruthenium (N719). Lapisan fotoelektroda TiO2 menggunakan pasta TiO2 ukuran 21 nm yang dideposisi menggunakan teknik spin coating dan pewarna N719 sebagai dye sensitizer. Counter elektroda Platina dideposisi menggunakan teknik sputtering. Parameter proses yang mempengaruhi karakteristik listrik sel surya dianalisa dan diukur. Karakteristik kurva I-V sel surya diukur menggunakan Kethely dengan variasi intensitas yaitu 100 Watt/m2, 250 Watt/m2, 500 Watt/m2, 750 Watt/m2 dan 1000 Watt/m2.Prototipe sel yang terbaik menghasilkan effisiensi sebesar 0,15%.Uji absorbansi menggunakan Spectrophotometer UV Visible 1601 PC dan uji sifat kelistrikan menggunakan Elkahfi 100/Meter I-V. Hasil menunjukkan bahwa pewarna organik sintesis ruthenium (N719) memiliki absorbansi yang kuat pada panjang gelombang 400-550 nm ini menjadikan dye ruthenium (N719) perlu untuk di selidiki sebagai bahan fotosensitizer DSSC.

Water based Remazol Brilliant Red, Orange and Violet dyes were used as the dye sensitizer in dye-sensitized solar cell. The performance of the solar cell was investigated between the dye concentrations, 0.25 mM and 2.5 mM and three different soaking times which at 3 hours, 12 hours and 24 hours. The adsorption peaks of the dyes were observed using ultraviolet-visible-near infrared (UV-Vis-NIR) Spectrometer and the performance of the dye-sensitized solar cell was measured using Spectrum Parameter Analyzer (SPA). The results show that the device efficiency was increased with dye concentration, but, the DSSC performance at different soaking times performed differently with the previous study. The highest conversion efficiency of 1.125 % was obtained for Remazol Brilliant Red at concentration of 2.5 mM at 3 hours soaking time.

AbstrakTelah dibuat Dye Sensitized Solar Cell (DSSC) yang dapat mengkonversi cahaya menjadi energi listrik denan memanfaatkan Black Dye N-749 sebagai dye sensitizer dan bahan semikonduktor TiO2 sebagai penyusun photoelektroda yang terdeposisi pada kaca ITO dengan luasan 1 cm2. Variasi dilakukan pada proses pembuatan photoelektroda, dimana proses dimulai dari photoelektroda yang dibuat menjadi single/double layer TiO2 yang terdiri dari lapisan nanopartikel pada lapisan dasar, sedangkan lapisan atas tersusun atas partikel berukuran sub-mikro. Proses selanjutnya adalah kompresi mekanik pada lapisan semikonduktor dengan beban 25 kg/satuan luas. Proses diakhiri dengan perendaman photoelektroda dengan tujuan mengadsorpsi partikel dye pada lapisan TiO2. Perendaman dilakukan menggunakan proses ultrasonik dengan waktu 20 detik. Hasilnya menunjukan bahwa setelah dilakukan kombinasi dari ketiga treatment maka efesiensi DSSC mampu meningkat dari 0,028% menjadi 0,040%.Kata Kunci: Dye Sensitized Solar Cell (DSSC); Photoelektroda, Double Layer; Kompresi Mekanik;Perendapam Ultrasonik; Efesiensi Solar SellAbstractDye Sensitized Solar Cell (DSSC) which is able to convert light into electrical energy by using Black Dye N-749 as a dye sensitizer and TiO2 semiconductor material as a photoelectrode has been conducted on 1 cm2 ITO glass area.
