Early Times Report JAMMU, Oct 6: Dr. Pankaj Biswas, Assistant Professor at the School of Physics, Shri Mata Vaishno Devi University, presented his research on "Optical Characterization and Upconversion Luminescence in KSrVO 4 :Er 3+" at the international conference POLY-CHAR 2025, recently held at theUniversity of Mauritius. His presentation focused on developing nanocomposite films of the KSrVO 4 :Er 3+ phosphor embedded in PMMA and PVP polymers for solar cell applications. These luminescent up-shifting layers, applied to the rear of solar cells, enhance efficiency by converting near-infrared photons into usable light-a key strategy for improving silicon-based solar devices. POLY-CHAR 2025, co-organized by the Centre for Biomedical and Biomaterials Research (CBBR), Mauritius, and the Wits Advanced Drug Delivery Platform (WADDP), South Africa, brought together experts from 21 countries including USA, Japan, Germany, India, and South Africa. The conference highlighted the convergence of polymer science and nanobiotechnologyto tackle global challenges in healthcare, sustainability, and advanced materials.The event also reinforced Mauritius' role as a growing scientific hub in the Indian Ocean, fostering international collaboration and innovation |
