Silicon-Based Tandem Solar Cells ISFH Collaboration Cooperative Research and Development Final Report

Summary

This final report details a collaborative research project between NREL and the Institute for Solar Energy Research Hamelin (ISFH) on silicon-based tandem solar cells, aiming to overcome efficiency limits of traditional single-junction PV technology. The project, under CRADA CRD-16-00606, focused on developing III-V/Si stacked tandem solar cells using transparent conductive adhesives. The U.S. Department of Energy committed an estimated total of $1,500,000.00 in shared resources across three years for this research. The effort successfully demonstrated a device with 27.3% efficiency and led to a joint publication in 2020.
