Researchers boost solar cells efficiency

 

 
According to Iran Nanotechnology Initiative Council (INIC), Iranian and Singaporean researchers applied an industrial, cost effective and simple method to boost the efficiency of dye-sensitized solar cells to convert solar energy into electrical one by creating nanometric changes in cell structures.
 
The aim of the research was to design and to produce nanostructured solar cells with high efficiency through engineering of the cell layers. Designing and production of solar cells by using two layers is a new approach in the production of these devices. In this method, a light scattering layer is added to the initial layer containing titanium dioxide nanoparticles. Surface area of the layer increases in this research due to the change in titanium dioxide nanostructure used in the scattering layer. Therefore, dye and light sorption capacity increase in these cells, and as a result, the efficiency increases too.
