Bio of M. Ryyan Khan

Dr. M. Ryyan Khan completed his BSc from EEE, BUET in 2009. He served as a lecturer in the same department for one semester. After completing his PhD from Purdue University, USA in 2016, he worked as a post-doctoral research associate in Alam CEED group (Purdue). He has been working at East West University as a faculty member since 2018. Dr. Khan’s recent work and interest include bifacial solar farm design through numerical model and experiments, solar panel soiling analysis, compound PV systems (agrivoltaics and floating-photovoltaics), and module reliability. He was part of the development team of four online modeling and learning tools in nanoHUB: (i) OPV Lab, (ii) PVLimits, (iii) PUMET, and (iv) PUB (bifacial module sim.). Combined, these tools have over 1000 users. He is a co-developer of a bifacial PV farm simulator: PV-MAPS (Photovoltaic Farm Modeling and Analysis Simulator by Purdue). Future versions are planned to gradually include tracking tandem bifacial, floating PV, PV on hills, soiling analysis, PV reliability, and agrivoltics. Dr. Khan also co-authored the book “Principles of Solar Cells: Connecting Perspectives on Device, System, Reliability, and Data Science” with Prof. M. A. Alam.
