ABSTRAKPada penelitian kali ini TiO2 nanotube dibuat dengan metode Rapid Breakdown
Anodization menggunakan plat Ti dalam elektrolit HClO4 0,15 M. Serbuk TiO2
dikalsinasi pada 4500 C selama 3 jam, dan dikarakterisasi dengan SEM, XRD, UV-Vis
DRS, FTIR and BET. Zinc-Phorphirin-Imide telah berhasil dilekatkan pada TiO2
Nanotube dengan merendam TiO2 Nanotube ke dalam larutan Zinc-Phorphirin-imide
selama 24 jam. zinc-Phorphirin bebas memperlihatkan karakteristik spektra serapan pada
daerah cahaya tampak, yaitu 439 nm and 620 nm. Saat dilekatkan dengan TiO2-
Nanotube terjadi pergeseran serapan padathe 421 nm dan 640 nm. Zinc-Phorphirin/TiO2
electrode memperlihatkan respon arus yang baik pada daerah cahaya tampak dengan
photocurrent density sebesar 1,1 mA/cm2. Saat fotoelektroda dirakit menjadi Solar Cell
(DSSC), kurva I-V menunjukkan efisiensi fotokonversi dari Zinc-Phorphirin/TiO2
DSSC sebesar 1,914% (frontside illumination) dan1,147% (backside illumination).
ABSTRACTIn this work, TiO2 Nanotube were prepared by rapid breakdown electro oxidation of Ti
foil in electrolyte containing 0.15 M HClO4. Obtained TiO2 Nanotube bundling powder
was calcinated at 4500 C for 3 hrs, then was characterized by SEM, XRD, UV-Vis DRS,
FTIR and BET. Zinc-Phorphirin-Imide dyes was deposited into TiO2 Nanotube by
immersion of TiO2Nanotube in Zinc-Phorphirin-imide solution for 24 hours. Free zinc-
Phorphirin-Imide dyes shows characteristics absorbtion spectra in visble region, these are
439 nm and 620 nm. While, when it was immobilized in to TiO2-Nanotube the
absorbtion peak shift to 421 nm and 640 nm. The Zinc-Phorphirin-Imide/TiO2 electrode
showed excellent respond toward visible light with the typical photocurrent density of 1,1
mA/cm2. When the fabricated photoelectrode was assemblied in a typical Dyes Sensitize
Solar Cell (DSSC), the I-V curve showed photoconversion efficiency of the assemblied
Zinc-Phorphirin-Imide/TiO2 DSSC was 1,914% (frontside illumination) and 1,147%
(backside illumination)."
