“Recent Progress in Thin Film Perovskite Solar Cells” Tara P. Dhakal, Ph.D., Associate Professor Department of Electrical and Computer Engineering Thomas J. Watson College of Engineering and Applied Science Binghamton University, State University of New York, Binghamton, NY 13902 Director, Center for Autonomous Solar Power (CASP) Binghamton University, State University of New York, Binghamton, NY 13902 Perovskites are being extensively explored for both solar cells and lighting applications. To say that perovskites are wonder materials for the optoelectronic industry is an understatement. Generally, perovskites have a three-dimensional ABX3 structure (A: organic or inorganic cation, B: metal cation, X: halogen) in which self-organized two-dimensional (2D) planes of organic layers (AX) are sandwiched between 2D planes of inorganic halides (BX2). Organic-metal halide perovskites have shown remarkable improvement in recent years, with efficiencies increasing from 3.8% in 2009 to 25% in 2020, which is close to long-commercialized silicon solar cells. This presentation will cover a general overview of various solar cell technologies and a discussion on the recent progress in perovskite thin film solar cells. In addition, our group’s work on the effect of buffer layers on both reliability and performance of the perovskite solar cells will be presented. Tara P. Dhakal received his B.S. and M.S. degrees in Physics and Material Science from Tribhuvan University, Kathmandu, Nepal and Shimane University, Matsue Japan in 1998 and 2001, respectively. He received his Ph.D. degree in Physics from the University of Florida, Gainesville, FL in 2008 where he studied complex magnetic oxide thin films. Following his graduation, he joined University of South Florida as a postdoctoral researcher and led research efforts in spintronics, solar and thermoelectric materials. He is currently Director of the Center for Autonomous Solar Power (CASP) established by Office of Naval Research (ONR)funding and holds an associate professor position at the electrical and computer engineering department at Binghamton University. His current interests are in super-capacitive energy storage, thin film perovskite solar cells and LEDs. Dr. Dhakal is currently developing lead-free stable perovskite solar cells through his NSF CAREER grant. Dr. Dhakal has also been developing a capacitive electrode based human heart ECG sensor, a project supported by NextFlex and AFRL. Dr. Dhakal has published three book chapters and more than 50 research articles in journals such as Nature Physics, Physical Review Letters, ACS Applied Materials and Interfaces, and IEEE Transactions on Device and Materials Reliability. He is a member of IEEE, and Material Research Society (MRS).
