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.
