Abstract

In this research cadmium oxide were prepared by using the chemical simple method, and a pours silicon has been fabricate by using the etching technique on the regular silicon, a solar cell is fabricated by deposited the cdo on the prepared pours silicon (Cdo/Psi) by the drop casting method and do the annealing process in three deferent temperatures (200,400,600) c˚. The XRD testes show that all the prepared samples are poly crystalline and cubic with orientations peaks (111,101,100,102). The optical testes show that these thin films have a high absorbency and low transmittance decrease with increasing the annealing temperature. The short circuit current (Isc) and the short circuit voltage (Vsc) of the fabricated solar cell showed that the conversion efficiency increase as the annealing process temperature increase until it become (9.3)% at (600)c˚.

Abstract

In this research, the sol-gel technique was used to prepare indium oxide nanoparticles. In addition, these particles are deposited by (dip coating technique) on a quartz substrate. Several measurement instruments (FTIR, SEM, UV-visible, and X-RAY diffraction) were used in this study to diagnose and analyze the properties of indium oxide (In2O3) particles at different parameters. The results from XRD indicated that the particle formation converted to a polycrystalline phase at different annealing temperatures (200 ℃ and 600 ℃) for an hour and a half. Also, the XRD results show an increase in the (grain size and lattice constant) with increased annealing temperature. The measurements of the Hall Effect showed the type of conductivity of (In2O3) particles is N-type, carrier concentration, mobility, and resistivity. The results of the sensitivity of indium oxide thin films to toxic gas, specifically carbon monoxide (CO) gas, showed an increase in the sensitivity of thin films annealed at high temperatures.

Abstract

This work describes the synthesis of cadmium oxide by a straightforward chemical process and its deposition onto a porous silicon substrate using the drop-casting technique. X-ray diffraction was utilized to determine the structure of the produced cadmium oxide (CdO). The results indicated that the CdO synthesized at room temperature is a cubic polycrystalline structure with a peak at 111. The grain size of the CdO exhibits a high level of homogeneity. The mean roughness of the produced CdO thin film was demonstrated using atomic force microscopy (AFM). The study utilized the optical properties of CdO, revealing its strong absorption and low transmission characteristics. A solar cell was created by depositing cadmium oxide onto prepared porous silicon to verify its high conversion efficiency of approximately 5.8%. The study examines the physical characteristics and effectiveness of a solar cell constructed using cadmium oxide placed on porous silicon.
