Abstract

Abstrak Telah difabrikasi dye-sensitized solar cell (DSSC) berbasis ZnO nanotree dengan variasi waktu sintesis dan jumlah PEG dengan metode preparasi Grätzel dengan suhu anil 200°C dan 300°C. ZnO nanotree dibuat dengan metode kopresipitasi dengan mereaksikan prekursor zinc nitrate hydrate dengan PEG (polyethylene glycol) dan HMTA. Preparasi fotoelektroda ZnO dilakukan dengan metode yang dilakukan oleh Grätzel dengan suhu anil 200°C dan 300°C untuk mendapatkan efisiensi yang besar. Fabrikasi DSSC menggunakan pewarna manggis sebagai pewarna alami. DSSC difabrikasi dalam bentuk struktur sandwich dengan menggunakan pasangan I3-/I- dan elektroda pembanding platina/karbon. Hasil karakterisasi ZnO menunjukkan ZnO nanotree belum mempunyai orientasi dan cabang yang tumbuh memanjang secara vertikal. Ukuran partikel terbesar terdapat pada variasi waktu sintesis 1,5 jam dengan jumlah PEG 3 dan hkl (101) sebesar 136,69 nm dan ukuran partikel terkecil terdapat pada waktu sintesis 4,5 jam dengan jumlah PEG 7 dan hkl (100) sebesar 32,94 nm. Untuk mendapatkan efisiensi DSSC dilakukan dengan menghitung hasil pengukuran dan dengan perhitungan berdasarkan teori dengan variasi nilai faktor idealitas sel surya yaitu 1, 1,5, dan 2. Berdasarkan karakteristik kurva I-V dan IPCE, diperoleh bahwa efisiensi terbaik berada pada waktu sintesis 4,5 jam dengan jumlah PEG 5 dan suhu anil 300°C. ======================================================================================================== Dye-sensitized Solar Cells (DSSCs) have been successfully fabricated based on ZnO nanotree with stirring time and PEG amount variation by Grätzel preparation method with annealing temperature of 200°C and 300°C. The precursor of ZnO Nanotree was synthesized by co-precipitation method, prepared by reacting Zinc Nitrate Hydrate with PEG (polyethylene glycol) and HMTA. Photoelectrode ZnO fabrication is done by Grätzel method with annealing temperature of 200°C and 300°C in order to get high efficiency. DSSC fabrication uses the extracts from mangosteen pericarp as a natural dye. DSSCs were fabricated in sandwich structure with I -/I- redox couple was employed as an electrolyte and platina/carbon was used as counter electrode. The characterization result shows that ZnO nanotree is not having backbone orientation and branch. The highest particle size was found in stirring time variation of 1.5 hour and PEG amount of 3 mM which is 136.39 nm hkl (101) and the lowest particle size was found in stirring time variation of 4.5 hour, PEG amount of 7 mM which is 32.94 nm hkl (100). The efficiency of DSSC is obtained from the measurement result and theoretical based calculation with solar cell ideality factor value variation of 1, 1.5, and 2. According to I-V curve characteristic and IPCE, the best efficiency was obtained in which annealing temperature was 300°C, stirring time was 4.5 hour, and PEG amount of 5.
