Amritsar, June 29

Dr Vibha Chopra, an assistant professor of physics at DAV College, Amritsar, has been working on productive ideas of increasing solar efficiency for the past three years. She in collaboration with Dr Sanjay Dhoble, a professor at RTM Nagpur University, now has successfully prepared down conversion phosphors, a material that will be useful for the enhancement of solar efficiency. The two have been granted international patent for their technology by the Australian Government.

“My research in the field of photo luminescence and its applications have been aimed towards solar efficiency and finding solutions for sustainable energy. Solar energy is fast an important means of renewable sources of energy these days. To increase the efficiency of solar cells, we have developed highly stable europium and terbium doped luminescent down conversion material, coating of which onto the surface of solar cell, results in increased efficiency of the cell. This technology could be a revolutionary step in photovoltaic technology,” she said. Earlier, Dr Vibha Chopra had developed automatic microcontroller based ice defrosting instrument and three UV based sanitisation units viz. for mobile phone, multipurpose units for daily usage items including fruits and vegetables and for PPE kits and police uniforms. The work was published in the form of Patents by Indian Government. This is the fifth patent to her credit, the earlier four being national patents. This work has been internationally recognised and patent is granted by IP Australia under the Australian Government.

She stressed on building scientific temperament in community and improving infrastructural support for researchers to encourage innovations. We need more grants and facilities to carry out research work in different fields of science, she said.

Principal Rajesh Kumar congratulated Dr Vibha Chopra and the inventors for this achievement. “Her research getting recognised internationally is a feat that speaks about her dedication and vision. It’s a proud moment for us as an institution and for all other educators from city that Dr Vibha has been consistently coming up with innovations to change the course of future,” he said.
