METHODS AND SYSTEMS FOR PREDICTION OF FILL FACTOR IN HETEROJUNCTION SOLAR CELLS THROUGH LIFETIME SPECTROSCOPY

摘要

Methods and systems for prediction of fill factor in heterojunction solar cells through lifetime spectroscopy are provided. In accordance with some embodiments, methods for categorizing fill factor in a solar cell are provided, the methods comprising: determining lifetime values of the solar cell at different minority carrier concentrations; determining a lifetime curve shape for the solar cell based on the determined lifetime values; and categorizing the fill factor of the solar cell based on the determined lifetime curve shape using a hardware processor.
