Indian Institute of Technology (IIT), Guwahati researchers have successfully developed a hybrid perovskite-based solar model which will use sunlight to produce electricity.
The newly developed device of IIT Guwahati is considered to be one of the most emerging perovskite-based semiconducting devices. The model will be used to harvest solar energy in the most low-cost and efficient way.
The device was designed and developed by the IIT Guwahati team of research scholars: Rabindranath Garai, Ritesh Kant Gupta, Arvin Sain Tanwar, and Maimur Hossain. The research was done under the supervision of Parameswar K Iyer, Professor, Department of Chemistry.
Referring to the initiative, IIT Guwahati Faculty Member, Parameswar K Iyer, said, "Organic-inorganic hybrid PSCs have experienced rapid growth in terms of efficiency and stability due to the development of highly efficient functional materials combined with careful device engineering".
"The materials design can be tailored at the molecular level whereas the fabrication process is printable and solution-based, making the overall solar cell development process economical and scalable" he further said.
IIT Guwahati Solar Energy Device: Key Highlights
- IIT Guwahati Research Team claims, solar energy can now be produced from sunlight (solar sources) at a very low cost.
- The IIT Guwahati Solar Energy Device will replace currently available technology for harvesting solar energy.
- As of now, the solar cells used to convert solar energy to electrical energy are said to be very expensive in cost and are non-recyclable.
- The development of IIT Guwahati will replace the previous models with recyclable and cheap solar cells that are not hazardous and complicated.
- The researchers have incorporated the charged conjugated polymers in photovoltaic devices as a passivation molecule. The incorporation further resulted in defect-free high-quality perovskite solar cell devices.
- The defect-free perovskite device has achieved an efficiency of 20.17%.
- With this development, the device will show excellent reproducibility and can be used for a long-term duration.
While talking about the significant highlights of the IIT Guwahati Solar Energy Model, Parameswar K Iyer, said, “The results obtained from perovskite solar cells have performed well beyond the commercial inorganic solar cells panels which are available in the market presently.The strategies being developed have the potential to address the renewable energy challenges regarding the large-scale commercial fabrication of efficient and stable solar panels.”
He further added that the performance of devices in small and large areas is showing the best results. The results have been accomplished with the help of these classes of perovskite materials.
Earlier on December 13, 2021, IIT Guwahati launched advanced Microelectronics and Nano Energy Facilities at its Nanotechnology Center. The center was inaugurated by Union Education Minister Dharmendra Pradhan on November 21, 2021. Under its Nanotechnology Center, the IIT Guwahati aims to facilitate research in the nanotechnology domain on the campus ground.
The research will be carried out in the field of health care, nano biomaterials, and micro and nanoelectronics. Highlighting the significance of Nano Energy Facilities at IIT Guwahati, TG Sitharam, Director stated that the center will offer state-of-the-art facilities for nanofabrication to research scholars.
"The center is poised to make major contributions in the areas of nanodevices development for healthcare, renewable energy-photovoltaics, light-emitting diodes, thin-film transistors, sensors, and other allied areas,” he further added.
