The simple fabrication of nanorods mass production for the dye-sensitized solar cell

Abstract

Abstract. ZnO nanorods were successfully synthesized by the plasma torch with the zinc powder as the source of ZnO. Several testing was conducted to examine the results of ZnO nanoparticles among others are X-ray fluorescence (XRF), Scanning Electron Microscopy (SEM), and X-ray diffraction (XRD). The results of ZnO nanorods diameter vary from 87 nm to 263 nm which can be seen from SEM images and it is length varies from 300 to 1000 nm. It was found from XRD data that a sharp peak occured at 36.253º. It is indicated a good crystal growth and agreed well with the standard data (JCPDF-ICDD card no.: 36-1451). Effects of electrical current variations of plasma torch of 20, 25, and 30 Amperes on the size of ZnO nanorods are indicated from aspect ratio (72.85, 87.42, and 103 nm). The effects of electrical current of plasma torch on the purity of ZnO were about 95.61%, 98.46%, and 96.49% respectively. The performance of the solar cell at the time with the values of Voc, Jsc, FF, and efficiency are 0.466 V, 1.524 mA/cm 2, , 51.95%, and 0.37% respectively. ZnO nanorods were successfully synthesized by the plasma torch with the zinc powder as the source of ZnO.

Pengaruh Tingkat Keasaman Larutan Penumbuh Pada Morfologi Nanorod

“…ZnO memiliki sifat elektrik dan termal yang unik, kestabilan kimia yang tinggi [1], mobilitas elektron sebesar 100 cm 2 V -1 s -1 [4], sifat optik yang transparan, fotostabilitas tinggi, dan tidak beracun [2]. Dengan sifat-sifat unggul tersebut, ZnO banyak digunakan pada berbagai aplikasi di bidang optoelektronika, seperti DSSC (Dye sensitized solar cells) [3], sensor gas, Light Emitting Dioda (LED), dan degradasi fotokatalis [4]- [6].…”

Nanomaterials: An Overview of Nanorods Synthesis and Optimization

“…Single crystal of ZnO exhibit significantly faster electron transport and greater mobility. The faster electron transport is a result of the high electron diffusion coefficients, which will provide significant advantages to device performance [28]. Since ZnO could emits at the near ultraviolet, has transparent conductivity and piezoelectric properties, thus, ZnO is an interesting material for semiconductor and laser devices, piezoelectric transducers, transparent electronics, surface acoustic wave devices, spin functional devices, and gas sensing.…”

Growth of ZnO Nanorods on ITO Film for Piezoelectric Nanogenerators

“…A single crystal of zinc oxide (ZnO) is known to have significantly fast electron transport properties as well as great mobility. The fast electron transport comes from the high electron diffusion coefficients, which provides significant advantages in terms of device performance [ 5 ]. Since ZnO has a large surface to volume ratio, which leads to the enhancement of the sensitivity, it is an excellent material for sensor application.…”
