Abstract
ZnO nanoflower telah disintesis dengan menggunakan metode
ko-presipitasi pada suhu 80°C untuk aplikasi Dye Sensitized Solar
Cells (DSSC). Nanostruktur ZnO berhasil ditumbuhkan dengan
variasi nilai derajat keasaman (pH) dari Zinc nitrate tetrahydrate
[Zn(NO3)2.4H2O], Hexamethylenetetramine (HMTA) dan Potassium
hydroxide (KOH). Hasil eksperimen mengindikasikan dengan
penambahan nilai pH dari 6 sampai 12, morfologi ZnO berkembang
dari partikel agregat, nanoflakes, nano prisma, dan pada akhirnya
membentuk struktur nanoflower. Berdasarkan persamaan Scherrer,
ukuran partikel dari puncak (100), (002), (101) dan (112) memiliki
variasi ukuran dari 40 nm sampai 69 nm. Pada proses anil, ukuran
partikel meningkat hingga 1,5 hingga 2 kali lipat dibandingkan saat
sintesis. HMTA diketahui sebagai stabilizer dan reduktor yang
efektif untuk memproduksi ZnO yang bervariasi terhadap panjang
dan penampang melintang. Preparasi pasta pada penelitian ini
dilakukan dengan variasi suhu dan waktu anil yaitu 200°C selama
30 menit dan suhu 300°C selama 60 menit. Hasil eksperimen
menunjukkan efisiensi terbaik didapat dengan menggunakan suhu
anil 200°C selama 30 menit dengan efisiensi 0,11 %, IPCE=
0,008611 %, FF= 0,25 %, Voc= 382 mV, Jsc= 0,11 mA/cm2
===================================================================================================
ZnO nanoflowers were synthesized by co-precipitation
method at low temperature (80˚ C) for dye-sensitized solar cell
applications. ZnO nanostructures were grown at various pH values
from Zinc nitrate tetrahydrate [Zn(NO3)2.4H2O], HMTA
(Hexamethylenetetramine) and Potassium Hydroxide (KOH). The
results indicate that by increasing pH from 6 to 12, the ZnO
morphology evolves from aggregrated particles, prism-like and
eventually flower-like structures. According the Scherrer equation
the particle size of (100), (002), and (101) peaks tends to drop as the
pH increased. HMTA is known as an effective reductant to produce
hexagonal ZnO rods of various lengths and cross-sections.
However, the effect of various ammount of HMTA on the crystallite
size in this research is somewhat complex, i.e. no particular trend
was observed. The only clear information was obtained through
SEM investigation which indicates that for low HMTA led to smaller
petal and further addition caused the petal became wider ad
eventually led the pronounced formation of the centered cone. Paste
preparation which employs annealing at 200˚ C or 300˚ C for up to
1 hour leads to further growth of the obtained crystal. The
experimental result show that the best efficiency was obtained for
temperatur annealing of 200˚ C for 30 minutes i.e 0,11 % with
IPCE= 0,008611 %, FF= 0,25 %, Voc= 382 mV, Jsc= 0,11 mA/cm2.
