Inexpensive Method Reduces Costs to Produce Light Sorbent Nanostructured Layers
Tehran, Iran | Posted on September 20th, 2015Researchers have tried to synthesize and study new nanostructured absorbing layers made of cheap and available elements with desirable physical properties because indium and gallium are very rare and expensive.
Iranian researchers succeeded in the production of light absorbing nanolayers by using available raw materials through a cheap method. The nanolayers have high light absorbing factor, and they can be used in the production of solar cells.
Researchers have tried in this research to produce CZTS nanostructured thin films by using zinc and tin elements that are widely found in nature and require reasonable cost. The films have been produced through a cost effective method. The optimum physical properties of the films are very promising to take the place of rare and expensive elements of indium and gallium as sorbent semi-conductors in solar cells.
Results obtained from the characterization of the produced samples confirm the formation of polycrystalline structure with homogenous surface coated with spherical nanoparticles. The produced samples have high light absorption at the range of visible light, and they also possess desirable electrical properties.
The researchers hope that the solar cells made of nanostructured films synthesized in this research can take the place of normal silicon solar cells to reduce the costs.
Results of the research have been published in Journal of Materials Science: Materials in Electronics, vol. 26, issue 6, 2015, pp. 3700-3706.
