Semi-transparent polymer solar cells with excellent sub-bandgap transmission for third generation photovoltaics

Semi-transparent organic photovoltaics are of interest for a variety of photovoltaic applications, including solar windows and hybrid tandem photovoltaics. The figure shows a photograph of our semi-transparent solar cell, which has a power conversion efficiency of 5.0%, with an above bandgap transmission of 34% and a sub-bandgap transmission of 81%. © 2013 WILEY-VCH Verlag GmbH & Co.

This research was based upon work supported by the Department of Energy through the Bay Area Photovoltaic Consortium under Award Number DE-EE0004946, and by the Center for Advanced Molecular Photovoltaics (CAMP) (Award no. KUS-C1-015-21) made by the King Abdullah University of Science and Technology (KAUST). Work was performed in part at the Stanford Nanofabrication Facility's nSiL lab, which was funded by National Science Foundation (award ARI-0963061). Additional funding was provided by the National Defense Science and Engineering Graduate Fellowship (Z.M.B.), the National Science Foundation Graduate Research Fellowship (A.R.B.), Baseline Research Funding from KAUST (P.M.B.), and the TomKat Center for Sustainable Energy. Thanks to Rommel Noufi at the National Renewable Energy Laboratory for providing the CIGS cell used as the bottom cell of the hybrid tandem devices.
