Mitigating Performance Degrading Defects in Gallium-doped Czochralski Silicon Solar Cells with Data-Informed Modeling

Payne Institute Faculty Fellow Sumit Agarwal received funding from the U.S. Department of Energy (DOE) Solar Energy Technologies Office (SETO) Small Innovative Projects in Solar (SIPS) for a project that studies light- and temperature-induced degradation observed in p-type silicon passivated emitter rear contact (p-PERC) solar modules. The team is using gallium-doped Czochralski silicon wafers to understand the high efficiency and reliability of p-PERC crystalline silicon (c-Si) modules by mitigating 30 years of degradation in the field due to light and thermal effects.  May 16, 2024.
