Abstract

Dalam penelitian kali ini, telah didemonstarsikan penggunaan Grafin Oksida (GO) sebagai material pengantar lubang pada sel surya hibrid Bulk-Heterojunction (BHJ). Sebuah metode sederhana digunakan dalam memodifikasi anoda dari sel surya hibrid dengan cara mendeposisi material karbon nano hasil proses larutan diantara kaca transparan indium timah oksida(ITO) dan lapisan fotoaktif. Perngguanan GO ini ditujukan untuk mengganti secara keseluruhan polimer konduktif poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS). Dengan penggunaan lapisan GO ini, perbaikan efisiensi konversi energi dari 0,1% menjadi 1,66 % dapat dicapai melalu mekanisme penurunan hambatan seri (RS). Dengan hasil ini GO telah berhasil menunjukkan potensial yang besar untuk digunakan sebagai material pengantar lubang yang efisien pada sel surya hibrid

Abstract

NANORODS ZnO THIN FILM PERFORMANCE AS TRANSPARENT HEATERS. Transparent heaters have been used for various applications. In this research, a transparent heater made from ZnO nanorods has been successfully fabricated. ZnO nanorods were produced by using the chemical bath deposition method.The results of the XRD investigation showed that the ZnO_0.015 and ZnO_0.025 samples contained three and five ZnO peaks, respectively, with a hexagonal wurtzite crystal structure. The crystallite size increased along with the increase in the solution concentration from 71.198 nm to 82.924 nm. The morphological characterization of the samples using FE-SEM showed that ZnO_0.025 sample had a better surface covarege than ZnO_0.015 sample. The average diameters of ZnO_0.015 and ZnO_0.025 are 127.130 and 146.756 nm, respectively. The transmittance value decreased along with the increase of solution concentration which is from 55% to 53%. The value of the band gap energy decreased as the concentration of the seed solution increased from 3.25 eV to 3.20 eV. The resistivity values of ZnO_0.015 and ZnO_0.025 are 1.126 x 10-4 and 0.824 x 10-4Ωcm, respectively. From these results it appears that ZnO_0.025 sample has a more optimal performance as a transparent heater compared to ZnO_0.015 sample.
