After qualifying among the toppers in Physics in NET, 1989, PrabirKantiBasu received his Ph.D. degree from BITS, Pilani, in the field of solid-state optoelectronic devices while working at National Physical laboratory, New Delhi. Thereafter, he joined in semiconductor fabrication industry in 1995 and received training at Germany. There he was involved in process optimization of zener diodes, power diodes, switching diodes, power transistors, and solar cells. Since 2003, he is teaching at LIMAT, (presently Lingaya’s University), Faridabad. In between, he has also worked as research professor at South Korean University on project of advanced solar cell research. He has published several research papers in reputed international journals such as IEEE Transactions on Electron Devices, Semiconductor Science and Technology, Renewable Energy, Materials Science letters, Solar Energy Materials and Solar Cells and presented several papers in International Conferences. Besides academics, he is actively involved in working with industry. Since 2006, he is working with Udhaya Energy Photovoltaics, Pvt. Ltd. Coimbatore, as visiting consultant.After completing M.Sc. with specializations in Electronics and Nuclear Physics, HrishikeshDhasmana qualified NET and GATE, 1999, in Physics, and received his M.Tech. degree from IIT, Bombay, in Materials Science and Engineering. He has already published papers in the journal of Frontier in Material Science and Technology, Renewable Energy, etc. After his M.Tech., he is actively involved in teaching in various engineering colleges. Since 2004, he is teaching at Lingaya’s, Faridabad. His areas of interest are solid-state materials, thin film, and semiconductor devices. Currently, he is pursuing Ph.D. from IIT Delhi in photovoltaic devices in Center for Energy Studies.
