A new publication in collaboration with ASU tracks the progress in photovoltaic module efficiency. Previously, efficiency has focused on the smaller solar cell but a practical product requires combing the solar cells into a larger module. The publication includes the most recent photovoltaic module records as well as the historical context by tracking performance sinc 1990. Following the evolution of these efficiencies enables researchers to track the progress of various technologies. The paper we analyzes champion module efficiencies and compares them to champion cell efficiencies to better understand technology trends over the last three decades. Recommendations are provided on how to change the data collection and reporting for champion efficiencies to increase the value of these records.

The publication was a collaboration amoung leading photovoltaic researchers in government, academia and industry. The full reference is: S. Kurtz, I. Repins, W. K. Metzger, P. J. Verlinden, S.
