Ahmad R. Kirmani is a postdoctoral researcher at NREL in the Chemical and Nanosciences Center. He is exploring solution-processed perovskite materials for applications in optoelectronics. A recent focus of his research is to understand radiation hardness of perovskite photovoltaics for space applications. He is also involved in techno-economic feasibility analysis of this newfangled technology.

Prior to joining NREL, Ahmad was a guest researcher at the National Institute of Standards and Technology, where he studied the thin-film formation kinetics of inorganic semiconductor inks during scalable coating using synchrotron-based time-resolved X-ray scattering. Structure-transport correlations in transparent metal oxides were also a major theme.

His doctoral research has provided an improved understanding of solar cells based on lead chalcogenide nanocrystals. A key highlight was the first demonstration of ambient-manufactured, blade-coated efficient solar cells based on colloidal quantum dots. Ahmad’s research has involved frequent experiments at synchrotron sources including Advanced Light Source, Brookhaven National Laboratory, Canadian Light Source, and Cornell High Energy Synchrotron Source. His research has so far resulted in more than 40 published papers and several conference presentations. He is also a volunteer science writer for the Materials Research Society wth more than 10 published news articles, perspectives, and opinions.
