Basic Research Opportunities in Photovoltaics

This talk presents an overview of basic research opportunities in all current technologies of interest for photovoltaic devices.  The majority of the opinions described will be based on a meeting held May 3, 1999, and organized by J. Benner, S. Deb, and R. McConnell of NREL at the request of James Rannels and the EERE Division in the Department of Energy.  The meeting was a follow-on to a meeting organized by A. Zunger under DOE/BES sponsorship in 1992.  Different technologies were represented by teams of experts in their area from the U.S. research community.  Each team discussed the issues relevant to their technology and presented their team perspective at the meeting.  Extended discussions took place during and after the meeting and the final result was a series of documents published in a proceedings.  Technologies represented included crystalline-Si, amorphous Si, chalcopyrites, CdTe, and InGaAsN for PV applications.  In addition, novel materials, transparent conductors, and characterization methods were discussed.  Other areas of interest drawn from recent work, from the Basic Energy Sciences Portfolio, and other resources will be included in the discussion.
