Dr. Sheila Bailey was a senior scientist in the Photovoltaics and Electrochemical Systems Branch at NASA Glenn Research Center, where she has worked from 1985-2018. She received her Bachelor’s (Duke) and Master’s (UNC) degrees in Physics and her Ph.D. in Solid State Physics (Univ. of Manchester, UK). She taught at Baldwin Wallace University for 27 years and has been an associate faculty member of the International Space University. Dr. Bailey’s PV work has centered around advanced etching, epitaxial lift off and quantum dot (QD) solar cells. She is co-author of over 150 publications in various aspects of solar cell materials processing and applications for space exploration. She has also authored numerous chapters in books and co-edited several books on this topic. She serves on editorial boards of several PV journals as a space PV expert.

Aloysius F. Hepp is Chief Technologist at Nanotech Innovations and an independent consultant based in Cleveland, Ohio. He earned a PhD in Inorganic Photochemistry in 1983 from MIT and retired in December 2016 from the Photovoltaic & Electrochemical Systems Branch of the NASA Glenn Research Center (Cleveland). He was a visiting fellow at Harvard University from 1992–3. He was awarded the NASA Exceptional Achievement medal in 1997. He has served as an adjunct faculty member at the University of Albany and Cleveland State University. Dr. Hepp has co-authored nearly 200 publications (including six patents) focused on processing of thin film and nanomaterials for I–III–VI solar cells, Li-ion batteries, integrated power devices and flight experiments, and precursors and spray pyrolysis deposition of sulfides and carbon nanotubes. He has co-edited twelve books on advanced materials processing, energy conversion and electronics, biomimicry, and aerospace technologies. He is Editor-in-Chief Emeritus of Materials Science in Semiconductor Processing (MSSP) and is currently the chair of the International Advisory Board of MSSP, as well as serving on the Editorial Advisory Boards of Mater. Sci. and Engin. B and Heliyon. He has recently been appointed as Series Editor for the Vacuum and Thin-Film Deposition Technologies series and the Aerospace Fundamentals, Applications, and Exploration series.

Dale C. Ferguson received the Ph.D. degree from The University of Arizona, Tucson, in 1974. He is currently the Lead for Spacecraft Charging Science and Technology with the Space Vehicles Division, Air Force Research Laboratory (AFRL), Kirtland Air Force Base, Albuquerque, NM. For nearly 40 years, he has been addressing spacecraft charging problems, first with the NASA and now with AFRL. He is the author of more than 200 publications. He has been the Principal Investigator on numerous spaceflight experiments, including the Wheel Abrasion Experiment on the Mars Pathfinder Sojourner Rover.

Ryne P. Raffaelle (RPR) earned both a BS and MS in Physics from Southern Illinois University and a Ph.D. in Physics from Missouri University of Science and Technology. He is the Vice President for Research and Associate Provost at Rochester Institute of Technology (R.I.T.).
