About Sourabh Dongaonkar

I am PhD candidate at the School of Electrical and Computer Engineering, Purdue University. I am a part of Network for Photovoltaic Technology. My work has focused on technology agnostic analysis and design of thin film photovoltaic modules, for variability and reliability considerations.
Specifically, my work has included -
• Gap between cell and module efficiency: An overarching goal of this work is to identify and address the persistent gap between lab and production efficiencies of solar cells.
• Long term performance reliability: We are working on building physics based understanding of reliability of solar cells, in order to enable a predictive reliability framework for all PV technologies.
• Metastable switching in thin films: We have found metastable switching behavior in parasitic shunts in thin film PV, which resembles the physics of non-volatile switching memories.
• Device physics of thin film solar cells: Development of physical compact model for thin film solar cells, including the intrinsic as well as parasitic current behaviors.
