Their breakthrough technology, based on formamidinium perovskite and plasmonic nanoparticles, exhibits enhanced light detection capabilities, with significant potential applications across healthcare, environmental monitoring, and solar energy industries.

Publish

The research, published in the prestigious ACS Applied Materials & Interfaces journal, was co-authored by Prof. P. K. Giri, Department of Physics, and his research scholars, Mr. Debabrata Sahu, Mr. Subhankar Debnath, and Mr. Sirsendu Ghosal, at IIT Guwahati.

The formamidinium-based perovskite used in this study is recognized for its better stability and high light conversion efficiency, say sources from IIT Guwahati.

However, enhancing its light absorption and electrical performance while keeping production costs low has been a challenge, say sources from IIT Guwahati.

To address this, the IIT Guwahati research team integrated an array of 2D printed plasmonic nanoparticles—tiny particles made of noble metals like silver (Ag)—into their perovskite photodetector.

These Ag nanoparticles array help focus light onto the perovskite layer through a process called localized surface plasmon resonance (LSPR), greatly boosting light absorption and efficient photodetection, says IIT Guwahati research team.

By incorporating 2D printed plasmonic nanoparticles into the design, we have significantly enhanced the device’s performance while ensuring scalability and cost-effectiveness, say sources from IIT Guwahati.

Technique

The team used a specialized microprinting technique to precisely arrange the silver nanoparticles, improving the device’s sensitivity while making the manufacturing process scalable and economical.

The photodetector remains stable under normal environmental conditions, ensuring durability for practical applications across various industries, say sources from IIT Guwahati.

Transform

This photodetector innovation could transform industries by improving medical imaging, enhancing environmental monitoring accuracy, and boosting solar energy efficiency—all through cost-effective production.

It paves the way for wider real-world applications and addresses key global challenges, say IIT Guwahati research team.

They cover all the major engineering, science, healthcare, management, and humanities disciplines, offering BTech, BDes, BSc(Hons), MA, MDes, MTech, MSc, MS(R), MBA and PhD programmes.

The institute offers a residential campus to 455 faculty members and more than 8,600 students at present.

IIT Guwahati has retained the 7th position among the best engineering institutions of the country, 9th position in ‘Overall’ and 10^th position in ‘Research’ Categories in the ‘India Rankings 2024’ declared by the National Institutional Ranking Framework (NIRF) of the Union Ministry of Education.

IITG has achieved rank 87 in the SDG 9 (Industry, Innovation, and Infrastructure) globally in the Times Higher Education (THE) Impact Rankings 2024 and is the only academic institution in India that occupied a place among the top 100 world universities – under 50 years of age – ranked by London-based Times Higher Education (THE) in 2014 and continues to maintain its superior position even today in various International Rankings.

IITG gained rank 32 globally in the ‘Research Citations per Faculty’ category and overall 344 rank in the QS World University Rankings 2025.

Among other frontier areas of research and innovation, IITG is working towards augmenting critical science research initiatives in Genomics, Developmental Biology, Health Care and Bioinformatics and Flexible Electronics, among numerous other areas.
