Researchers at the Indian Institute of Technology, Hyderabad IIT-H, have established a novel method to enhance the performance of the third generation solar cells. Functioning with Dye Sensitised Solar Cells DSSCs, they have revealed that the integration of magnetic nanoparticles FeO in the anode can improve light-to-power exchange productivities.

Their greatest current effort has been published in the journal Solar Energy, a peer-reviewed journal.

The inexpensive and eco-friendly energy source

There are abundant potentials for DSSCs due to the cost and environmental advantages and it is anticipated that with enhancements in performance, DSSCs might exceed mature silicon-based solar cells in terms of performance. The international DSSC market is projected to reach millions of US dollars by the next few years.

The research is currently led by Jammalamadaka Suryanarayana, an Associate Professor, Magnetic Materials and Device Physics Laboratory, Department of Physics, IIT-H, with his student Kannan U.M in collaboration with L. Giribabu, senior scientist, Indian Institute of Chemical Technology, Hyderabad.

“Photovoltaic or solar cell technology has been in existence even before the last century and we are now coming to discover the third generation of cells. However, first-generation silicon-based cells continue to be costly. The Second-generation solar cell was based on thin-film solar cells constructed on semiconductors like CdTe and CdSe and they have comparable efficiencies, however, they are not much lower in cost. Meanwhile, the third generation cells, in its latest development, on the other hand, can considerably reduce the costs of solar cells while being environmentally safer, however, their competences require enhancement to transform to more useful products applications,” said Prof. Suryanarayana.

The proficiency of these solar cells was also known in the scientific community as ‘the Grätzel cell,’ after its inventor Michael Grätzel. The technology continues to linger around and there had been considerable researches all over the world to improve its performance which majority are still ongoing including this very research and its discoveries.
