Director

Christiana Honsberg (Bio)

Christina Honsberg received her PhD from the University of Delaware in 1992. Until 2000, Dr. Honsberg was faculty at the University of New South Wales in Sydney, Australia, working on high efficiency commercial silicon solar cells (the buried contact solar cells which were transferred to multiple industrial partners), advanced concept photovoltaics, and on the world’s first undergraduate degree program in photovoltaic engineering. In 2001, Dr. Honsberg became faculty at Georgia Institute of Technology working on ultra-high efficiency and in 2004 Dr. Honsberg joined the University of Delaware to develop a high efficiency solar program there. This resulted in an NSF-IGERT and a DARPA program, VHESC, focused on 50% solar cells, culminating in the “champion” sub-module efficiency of 38%. In 2008, Dr. Honsberg joined Arizona State University, founding the Solar Power Laboratory. In 2010, she became Director of the NSF-DOE Engineering Research Center QESST, focused on developing PV technologies and educational activates which address the Terawatt Challenge.

Stuart Bowden (Bio)

Director of Silicon Program

Stuart Bowden received his Ph.D. from the University of New South Wales (UNSW) in 1996 for work on static concentrators using silicon solar cells. The solar cell efficiency tester “DarkStar” that he developed during his PhD is still in use over 20 years later for detail characterization of solar cells. Following graduation, he transferred the buried contact solar cell technology from UNSW to Samsung Advanced Institute of Technology In 1998, he joined the Inter-University Micro Electronics Centre (IMEC) in Belgium where he demonstrated rear surface passivation of multicrystalline silicon wafers using boron diffusions and inversion layers. In 2001, he joined Georgia Institute of Technology where he worked on molecular beam epitaxy and the characterization of interface states in a variety of oxide materials. From 2004 – 2008 he led the effort at the University of Delaware on advanced silicon solar cell structures with the first publication on interdigitated back contact heterostructure silicon solar cells. Dr Bowden worked with Sinton Consulting (now Sinton Instruments) from 2001 to 2008 on the development of quasi-steady state lifetime testers and Suns-VOC systems. The testers have become standard characterization tools in the majority of solar production and laboratories throughout the world. In 2005, was awarded an R&D 100 award for his contributions to the Quasi-steady-state photoconductance system that is manufactured by Sinton Instruments. He is the author of the www.pveducation.org that is used for photovoltaic education in industry and academia throughout the world. Dr Bowden is presently the co-Director of the Solar Power Laboratory at Arizona State University where he develops high efficiency solar cells for terawatt production.

Bill Dauksher

Research Lab Manager

Bill Dauksher earned a B.S. degree in Materials Engineering from Rensselaer Polytechnic Institute in 1988 and an M.S. degree, also in Materials Engineering, from North Carolina State University two years later. After serving nineteen years as a Distinguished Member of the Technical Staff in Motorola Labs working on myriad aspects of semiconductor and cell phone research and development, he joined Arizona State University in 2009 as technical manager for the Solar Power Laboratory. Mr. Dauksher enjoys working on advanced silicon-based solar cell technology and holds 26 U.S. patents and two defensive publications. Additionally, he is author or co-author on over 100 peer-reviewed journal papers.
