Abstract

Dye-sensitized Solar Cell (DSSC) berbasis nanorod ZnO dengan variasi metode preparasi pasta telah difabrikasi sesuai dengan metode Yonekawa dan Grätzel dengan variasi temperatur anil. Nanorod ZnO disintesis dengan metode kopresipitasi yaitu dengan mereaksikan prekursor Zinc Asetat dengan EG (ethylene glycol) pada temperatur 200°C selama 5 jam. Sintesis nanorod ZnO dikarakterisasi menggunakan XRD dan SEM. Preparasi fotoelektroda ZnO dilakukan berdasarkan metode yang dilakukan oleh Grätzel dan Yonekawa. Selain itu, dilakukan variasi temperatur anil pada fotoelektroda. Pewarna kulit manggis digunakan pada fabrikasi DSSC sebagai pewarna alami. DSSC difabrikasi dalam bentuk struktur sandwich menggunakan pasangan redoks I3 - /I- dan elektroda pembanding platina. Hasil karakterisasi ZnO menunjukkan ZnO memiliki ukuran partikel sebesar 70,48 nm (100), 106,99 nm (101), dan 106,45 nm (002) dengan ukuran partikel rata-rata sebesar 96,64 nm. Berdasarkan karakteristik kurva I-V dan IPCE, diperoleh bahwa efisiensi terbaik jika preparasi pasta dilakukan pada suhu 300°C dengan menggunakan metode Yonekawa yaitu sebesar 0,05% dengan IPCE 0,00825%, FF 0,4%, Jsc 64µA/cm2 , Voc 275 mV). =================================================================================================== Dye-sensitized Solar Cells (DSSCs) based on nanorod ZnO have been successfully fabricated with paste preparation Yonekawa and Grätzel methods with various annealing temperature. ZnO nanorods were synthesized by co-precipitation method, at 200°C for 5 hours by using Zinc Acetate with EG (ethylene glycol). The synthesized ZnO nanorods were characterized by XRD and SEM in order to confirm phase purity and morphology of the samples. The sensitizer chosen was mangosteen pericarp extract with absorbance peak of 392.5 nm. The particle sizes obtained were 70.48 nm (100) plane, 106.99 nm (101) plane, dan 106.45 nm (002) plane with 96.64 nm being the average of particle size. The average nanorod diameter calculated using image-J software was found in the range of 90-150 nm. However, the resulted nanorods showed non-uniform vertical alignment. The experimental result shows that the best efficiency was obtained for temperature annealing of 300°C according to Yonekawa’s method i.e 0.05% with IPCE = 0,00825% , FF = 0,4%, Jsc = 264µA/cm2 , Voc = 275 mV.
