Our recent work highlighted in SPIE News!!
Welcome to the Thin-film and Photovoltaics Lab (TPL) website.
We are proudly housed within the Department of Physics at the Indian Institute of Technology (IIT) Dharwad. Our lab serves as a vibrant hub for cutting-edge research in thin-film materials and photovoltaic technologies, with a strong emphasis on innovation, interdisciplinary collaboration, and real-world impact.
This website is designed to be a gateway into the diverse research activities carried out by our group. Here, you will find insights into our ongoing projects, publications, and collaborative initiatives that aim to advance the frontiers of solar energy conversion. Beyond showcasing our scientific endeavors, the site also reflects our commitment to training the next generation of researchers, fostering creativity, and building bridges between academia, industry, and society.
Whether you are a prospective student, a fellow researcher, or simply curious about renewable energy, we invite you to explore our work and engage with the exciting developments emerging from TPL. Together, we strive to contribute toward sustainable energy solutions and a brighter future.
The group acknowledges the support by the Department of Science and Technology (DST) of India through the grants- SB/S2/RJN-048/2016, DST/NM/NT/2018/146, ECR/2018/002132 and CRG/2022/004055.
