Iranian researchers used titanium dioxide nanoparticles to design and test a special coating to increase the efficiency of dye-sensitized solar cells
TEHRAN (INIC)- Iranian researchers from Abar Nanofanavar Pishgam Sharif Company used titanium dioxide nanoparticles to design and test a special coating to increase efficiency of dye-sensitized solar cells.
Results of the experiments prove the increase in the efficiency of the produced cells. The solar cells can be used to produce electricity for industrial applications, including domestic appliance, automotive and aerospace after being mass produced.
In recent years, dye sensitized solar cells have become very important as the third generation of solar cells. The cheap equipment has very simple production technology and they are appropriate replacements for the expensive silicon cells. However, studies should still be carried out on increasing the efficiency of the new cells because they have low yield in the conversion of solar energy to electrical one. The aim of the research was to produce and study the performance of a type of coating to be used in dye sensitized solar cells.
Titanium dioxide nanoparticles doped with elements such as strontium and chrome were used in the production of the coating. It can be expressed that the increase in the efficiency of the cells in comparison with the cells produced on the base of usual coatings containing titanium dioxide is due to the increase in the current density in their short circuits.
Among other advantages of the cells, mention can be made of simple production method, appropriate final price and high transparency for the light.
The coating of nanoparticles contains titanium dioxide and other spherical nanoparticles in average size of 60 nm. Crystalline structure, chemical structure and composition of the coatings have been controlled in a way that it increases the current density in short circuits of dye sensitized solar cells.
Results of the research have been published in Journal of Colloid and Interface Science, vol. 460, 2015, pp. 18-28.
