Iranian researchers used a new inorganic pre-cursor in the presence of microwave and succeeded in presenting a novel method for the synthesis of a semi-conductor which can be used in solar cells.
Indium/Copper Sulfide Compound Semi-Conductor Synthesized through New Method
Tehran, Iran | Posted on September 8th, 2014 Decreasing the cost and increasing the production rate, reducing pollution and high purity are among the abilities of the new method. This method can be considered as an important step towards the industrial production of the material due to its high speed and low operational temperature.
The conversion of solar energy to electricity is one of the green and clean methods to produce electricity. The conversion is possible by using appropriate materials with photovoltaic properties. Indium/copper sulfide semi-conductive compound is one of these materials. This material has attracted the attention of researchers due to its high sunlight adsorption coefficient. Many methods have so far been proposed for the synthesis of this nanostructure, among which microwave is one of the most appropriate methods to heat the production process and synthesis. The researchers produced indium/copper sulfide semi-conductive compound by using a new inorganic precursor in the presence of microwave.
Semi-conductors have photoluminescence properties. The intensity of the properties varies when the material is in bulk (non-nanometric scale) or at nanometric scale. Nanometric materials have better photoluminescence properties, which results in increase the efficiency of solar cells.
In a simple comparison between the presented method and other methods, it was turned out that this method requires less operational temperature but it has higher speed. In addition, nanoparticles produced in this method are smaller in size.
Results of the research have been published in Journal of Industrial and Engineering Chemistry, vol. 20, issue 5, 25 September 2014, pp. 3800-3807.
