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.

This project is to investigate the counter electrode material from two different carbon sources to fabricate dye sensitized solar cell (DSSC). The carbon sources are extracted from battery and pencil lead. The method to prepare the DSSC is through the conventional Dr.Blading method. The same method is also used for the counter electrode which uses carbon from recycle batteries, the carbon from pencil lead are scribbled onto the ITO glass to get a uniform coating. Both thickness of the counter electrode vary accordingly. The solar cells are then placed under outdoor solar irradiation and the output is taken every 10 minutes. Based on observation, the solar cells which have the carbon from batteries shows higher cell efficiency which is 8.2 % with lower FF of 0.78, compared to by using the pencil lead, the cell efficiency is only 7.23% but with a higher FF of 0.93.

AbstractBiological fabrication approaches were used to enhance the performance of a dye-sensitized solar cell (DSSC) device stack for the conversion of light to electricity. Diatoms are single-celled algae that make silica shells called frustules that possess periodic structures ordered at the micro- and nanoscale. Nanostructured TiO2 was deposited onto the frustule biosilica of the diatom Pinnularia sp. Poly-L-lysine (PLL) conformally adsorbed onto surface of the frustule biosilica. The hydrolysis and condensation of soluble Ti-BALDH to TiO2 by PLL-adsorbed diatom biosilica deposited 0.77 ± 0.05 g TiO2/g SiO2 onto the diatom biosilica. The periodic pore array of the diatom frustule served as a template for the deposition of ˜20 nm TiO2 nanoparticles, which completely filled the 200 nm frustule pores and also coated the frustule outer surface. This material was then integrated into the DSSC device stack. Specifically, a single layer of diatom-TiO2 frustules was deposited to surface coverage 100μg/cm2 on top of the 25 nm anatase TiO2 nanocrystal layer (2.5 mg/cm2) that was doctor-bladed onto conductive FTO glass. The composite structure was thermally annealed in air at 400 °C, followed by addition of N719 dye, I3-/3I- liquid electrolyte, and semi-transparent Pt back electrode sputter coated on FTO glass. The solar cell efficiency increased from 0.20% to 0.70% when the diatom-TiO2 layer was added to anatase TiO2 base layer of the semi-transparent device. The increase in efficiency cannot be attributed solely to the added TiO2, because the amount of TiO2 in the diatom-TiO2 layer contributed to only 3% of the total TiO2 in the device. Instead, it is proposed that the diatom-TiO2 layer may have helped to improve photon capture within the DSSC because of its periodic structure and high dielectric contrast.

Dye-sensitized solar cell (DSSC) is being extensively investigated as the next generation energy source. Despite of the attractive features like simple fabrication process and its economic efficiency, there are some problems such as low efficiency, long fabrication time and low long-term stability. Conventionally, the dye adsorption on TiO2 photo-electrode film needs long time in the solvent with low concentration of dye to get the high efficiency. In this work, the dye coating process was considerably shortened, albeit plenty of dye was used comparing with the conventional way. Our needs were met for the best result in our working environment and the relevant conditions to our work were obtained, which were the coating temperature of 70 °C, the dye concentration of 10 mM and the coating time of 3 min. And this coating process was successively repeated several times to maximize the dye adsorption and to improve the cell efficiency. Therefore, the efficiency increased by 13% in the proper condition.

Soaking Temperature

Dye-sensitized solar cell (DSSC) is a photoelectrochemical solar cell that is able to convert solar energy into electrical energy. Sintering of TiO2film and soaking process of TiO2film in the dye solution have significant effect on the DSSC performance. The TiO2film was sintered at varied temperature from 200 °C to 500 °C for 60 minutes. From the efficiency test, it is found that the optimum performance of DSSC was produced when the TiO2film was sintered at 450 °C. In addition, the dye soaking temperature was evaluated from the temperature 40 °C to 50 °C for 6 hours. The optimum soaking temperature was 50 °C of DSSC with maximum efficiency at 2,621 %.
