Dr. Garima Aggarwal, Senior Manager-R&D at Waaree Energies Limited, gave a seminar at NCPRE on “Thin-Film Process Development and Charge Transport Study in BaZrS3: An Emerging Absorber for Photovoltaic Applications” on August 21, 2025. She presented recent progress in developing a scalable, industry-compatible thin-film process for BaZrS3 with improved phase purity and crystallinity. Additionally, she demonstrated how the electronic conductivity and carrier type in BaZrS₃ can be effectively tuned from near-intrinsic p-type to degenerate n-type via controlled sulfur vacancy engineering. Her talk provided valuable insights into the doping behaviour and application potential of BaZrS3 and related chalcogenide perovskites in next-generation optoelectronic technologies.
