Sintesis Carbon Nanodots dengan Metode Microwave Irradiation serta Aplikasinya sebagai Sensitizer Sel Surya Dye-Sensitized Solar Cell
ABSTRAK
Sintesis material C-Dots menggunakan metode microwave irradiation pada kondisi 450 W dengan variasi waktu 15, 30, dan 45 menit telah berhasil dilakukan. Tujuan dari penelitian ini adalah mengetahui karakteristik dari material C-Dots serta membuat prototipe untuk mengetahui efisiensi konversi dari sel surya Dye-Sensitized Solar Cell berbasis C-Dots. Karakteristik optis dari C-Dots dilakukan melalui uji fotoluminesensi, analisa FTIR, dan Spektrofotometer UV-Vis, sedangkan karakteristik morfologisnya melalui uji TEM. Hasil dari uji fotoluminesensi menunjukkan emisi tertinggi pada panjang gelombang 521 nm untuk material C-Dots yang disintesis selama 15 menit. Analisis FTIR mengindikasi adanya serapan khas dari C-Dots, yaitu gugus O-H pada 3429 cm-1, N-H pada 3300 cm-1, C-H pada 2850 cm-1 dan C=O pada 1700 cm-1. Pengukuran UV-Vis menunjukkan bahwa fotovoltaik C-Dots optimal pada spektrum ultraviolet. Hasil Analisa TEM menunjukkan C-Dots berbentuk bola-bola tidak seragam dengan diameter 9,4 nm. Fabrikasi prototipe Dye-Sensitized Solar Cell berbasis C-Dots berhasil dilakukan dengan efisiensi konversi 0,287 %.
ABSTRACT
Synthesis of C-Dots material using microwave irradiation method at a condition of 450 W with a variety of time of 15, 30, and 45 minutes has been successfully carried out. The purpose of this study was to determine the characteristics of C-Dots material and create a prototype to determine the conversion efficiency of Dye-Sensitized Solar Cell solar cells based on C-Dots. The optical characteristics of C-Dots were carried out through Photoluminescent test, FTIR analysis and UV-Vis Spectrophotometer, while the morphological characteristics were carried out by TEM test. The results of the Photoluminescent test showed the highest emission at a wavelength of 521 nm for C-Dots material which was synthesized for 15 minutes. FTIR analysis indicates the typical absorption of C-Dots, namely the O-H group at 3429 cm-1, N-H at 3300 cm-1, C-H at 2850 cm-1 and C=O at 1700 cm-1. UV-Vis measurements showed that C-Dots photovoltaics were optimal in the ultraviolet spectrum. TEM analysis results show that the spherical C-Dots are not uniform with a diameter of 9.4 nm. Fabrication of C-Dots-based Dye-Sensitized Solar Cell prototypes were successfully carried out with a conversion efficiency of 0.287%.
