Abstract

Tulisan ini menjelaskan aplikasi  pasta TiO2 reflektor (atau elektroda kerja dengan light scattering layer) pada sel surya berbasis dye-sensitized  (DSSC). Preparasi pasta dilakukan menggunakan bahan komersial yaitu pasta T-Nanooxide D-L (Solaronix) dan serbuk pasta WER2-O (Dyesiol) sebagai bahan reflektor. Bahan tersebut dianalisis struktur kristalnya. Hasil karakterisasi X-Ray Diffraction (XRD) menunjukan bahwa bahan TiO2 serbuk yang digunakan adalah nanokristal dengan struktur kristal anatase. Pembuatan pasta dilakukan melalui pencampuran serbuk pasta menggunakan pelarut ethanol dan larutan HCl tanpa binder. Penambahan TiO2 reflektor sebagai light scattering layer pada pasta dilakukan untuk melihat pengaruhnya terhadap karakteristik sel surya yang dihasilkan. Pasta ini dideposisi di atas permukaan plastik dan kaca konduktif (ITO-PET dan FTO) dengan metode doctor blade. Proses sintering lapisan TiO2 dilakukan pada suhu 120˚C selama 4 jam. Lapisan TiO2 yang terbentuk dianalisis morfologi permukaan menggunakan Scanning Electron Microscopy (SEM). Hasil SEM menunjukan bahwa dengan penambahan TiO2 scattering pada pasta ukuran partikel yang lebih besar dapat teramati. Lapisan TiO2 yang terbentuk diaplikasikan pada DSSC sebagai fotoelektroda. Pewarnaan dengan larutan N-719 (Ruthenium Complex), lapisan elektroda kerja Platina dan larutan elektrolit iodine. Karakteristik kurva I-V dengan ukuran sel daerah aktif 1 cm2 diukur menggunakan sun simulator AM1,5 dengan sumber cahaya Xenon dan intensitas 50 mW/cm2. Hasil pengukuran menunjukkan penambahan serbuk TiO2 reflektor (serbuk scattering) dapat meningkatkan unjuk kerja sel surya yang dihasilkan. Karakteristik I-V yang terbaik dihasilkan oleh DSSC campuran pasta Solaronix dan bubuk TiO2 reflektor menghasilkan efisiensi mencapai 0.166% dan pada substrat kaca mencapai efisiensi 0.167%.Kata kunci: dye sensitized solar cell, Pasta TiO2  suhu rendah, light scattering layer Characterization of Low Temperature TiO2 Paste and Their Applications in Light Scattering Layer of Dye Sensitized Solar Cell (DSSC)This paper describes the application of TiO2 paste reflector (or working electrode with a light scattering layer) in dye - sensitized solar cell (DSSC) . Preparation of paste is done using commercial materials T - Nanooxide DL (Solaronix) and WER2 - O powder (Dyesiol) as a reflector. The crystal structure of the material was analyzed. Characterization of X - Ray Diffraction (XRD) showed that the material used is TiO2 nanocrystal powders with anatase crystalline structure. Making pasta is done by mixing the powder paste using ethanol solvent and HCl solution without binders. The addition of TiO2 reflector as light scattering layer on the pasta is done to see its effect on the characteristics of the resulting solar cell. This paste is deposited on the surface of the plastic and conductive glass (ITO - PET and FTO) by the doctor blade method. TiO2 layer sintering process carried out at a temperature of 120 ˚ C for 4 hours. TiO2 layer formed surface morphology was analyzed using Scanning Electron Microscopy (SEM). SEM results showed that the addition of TiO2 paste scattering at larger particle sizes can be observed. TiO2 layer formed as photo-electrode applied in DSSC. Staining with a solution of N - 719 (Ruthenium Complex), a layer of platinum working electrode and electrolyte solution iodine. Characteristic IV curve with a cell size of 1 cm2 active area was measured using a sun simulator AM1, 5 with Xenon light source and intensity of 50 mW/cm2. The measurement results show the addition of TiO2 reflector powder (powder scattering) can improve the performance of solar cells are produced. IV characteristics of DSSC are best produced by a mixture of paste and powder TiO2 Solaronix generate efficiency reflectors reach 0.166 % on plastics and 0.167% on glass substrate.Keywords: dye sensitized solar cell, low temperature TiO2 paste, light scattering layer

Abstract

The performance of dye-sensitized solar cells (DSSC) is affected by its components. One of the affecting factors is counter electrode. Counter electrode has a function as a catalyst to fasten reaction kinetics during the tri-iodide reduction reaction within the cell. In this paper, the fabrication process of DSSC based on carbon nanoparticle counter electrode is described. The carbon nanoparticle was prepared into carbon paste with variation of solvent. The carbon nanoparticle paste was deposited onto FTO glass substrate (fl uorine-doped tin-oxide) by screen printing tehnique using stainless steel screen. The Characteristic of I-V curve of carbon counter electrode cells was measured using Oriel Sun simulator AM 1.5 with the light intensity of 40 mW.cm-2. The result was compared to cells which are based on platinum counter electrode. The best effi ciency of the cell obtained was 2.0%. and 3,12% for carbon nanoparticle and platinum counter electrode, respectively.

Abstract

The aim of this research is to study dye-sensitized solar cells (DSSC). This was implemented on a flexible polyethylene terephthalate (PET) substrate using a mixture of transparent and scattered mesoporous anatase-titania as the electron transport layer for the photoelectrode. This mixture of anatase titania performed a dual function of light scattering and efficient dye absorption. In this study, a porous nano-TiO2 film was prepared on indium tin oxide (ITO) coated polyethylene terephthalate (PET) by using a binder-free titania paste; on it, a DSSC was fabricated. The paste which contained a mixture of TiO2 nanoparticles, acid chloride, and ethanol was printed on two patterns of 1x6 cm2 active areas followed by sintered at 120 ºC to form TiO2 films. A commercial dye, N719, was adsorbed on the surface of TiO2 films and assembled to two platinized conductive plastic patterns to form a counter electrode and thus a sandwich-type dye cell. Finally, a solution of KI/I2 electrolytes was injected into the cell in which a couple of sandwich-type dye cells with an active area of 6 cm2 for each cell were series interconnected with a z-type interconnection between the photoelectrode of one cell and the counter electrode of another cell. The cell performance was characterized by employing simulated solar light at an intensity of 50 mW/cm2. The results showed interconnected cells generating a short-circuit photocurrent density of 2.34 mA/cm2, an open-circuit voltage of 1.10 volt, and overall 0.172% power conversion efficiency.
