Amrita Centre for Nanotechnology (ACNT) develops low cost nanomaterial based dye-sensitised solar cells (DSSC) with lab efficiency of 9.5%

As Panchabuta had reported last year, researchers from Amrita Vishwa Vidyapeetham -Department of Electronics and Electrical Engineering at the Bengaluru campus had begun work on a DST-funded project supervised by Dr. Manjula G. Nair to study ways in which to improve the power quality of wind-generated electricity.

The project involves the design and development of a laboratory prototype model of a digitally-controlled three-phase hybrid filtering system.

A study model of a windmill-cum-solar PV generating unit was installed on campus for this purpose.

According to a report today, a 15-member parliamentary committee visited the Nano Solar Division of the Amrita Centre for Nanotechnology (ACNT) to look at the various research facilities and work being carried out under the funding of the Ministry of New and Renewable Energy.

Addressing a press conference, the chairman of the committee P C Chacko said that they were impressed with the work done on solar photovoltaic cells and would recommend to the government to continue financial support to the project.

“The SPVs will help generate as well as store energy in the same panel. It will revolutionise the energy scenario in the country,’’ Chacko said.

According to the report, the nano centre was established at Amrita in 2008, initially with the funding from a central grant from India’s Nano Mission of the Department of Science and Technology (DST). Under this funding from DST, Amrita developed a product-oriented programme for manufacturing solar cells using nanomaterials which are low cost but effective.

The approach was to use what is known as dye-sensitised solar cells (DSSC) which use the principles whereby plants manufacture food using solar energy. Under the DST program Amrita successfully produced a lab scale version of DSSC with an efficiency of 9.5 percent, which is at the leading edge of current international standards.  

The Centre has also developed and patented a new technology whereby solar energy is produced and stored in the same panel; a revolutionary technology that is expected to change the way energy is utilised. In this concept, solar energy generated in one layer is stored in another layer using super capacitor technology. All the principles of the new device are based on nanotechnology and nanomaterials that are indigenously produced at Amrita using low cost processing methods.
