Silicon is the dominant technology for terrestrial photovoltaic applications and has recently exhibited remarkable progress in moving along the learning curve and thereby dramatically reducing the cost of solar power. The cost reduction is primarily due to the economies of scale attained by the cell manufacturing companies, with minimal improvement of technology. In silicon photovoltaics, a critical domain of research is the development of devices with advanced architectures. Two architecture of particular importance are silicon solar cells with carrier selective contacts and tunnel oxide passivated contact solar cells. In this talk, the focus will be on covering in detail the device theory and operation of such solar cells, along with presenting pertinent experimental results. Furthermore, the talk will also cover preliminary results on the analysis of thermal profile and moisture ingression as required for modeling of the microclimate of the photovoltaic module.
Dr. Kunal Ghosh received his Bachelor’s degree in instrumentation and electronics engineering from Jadavpur University in 2006. He completed his master and doctoral degree both in electrical engineering from University of Delaware and Arizona State University in 2008 and 2011 respectively. After completing a post-doctoral fellowship in QESST Engineering research center at Arizona State University, he joined IIT Mandi in 2014 as an Assistant Professor in the School of Computing and Electrical Engineering. Dr. Ghosh’s area of expertise is in design and fabrication of silicon solar cells.
