The National Science Foundation (NSF) awarded a 3-year, $425,000 Project Grant under the Engineering program (CFDA 47.041) to the University of California, Davis to investigate the stability and performance of halide perovskite solar cells. The research aims to:
-
Determine the combined effects of environmental stressors like humidity, oxygen, and temperature on perovskite stability through in-situ optical and X-ray diffraction measurements.
-
Quantify the stability of perovskite-hole transport material interfaces using novel conducting polymers to enable high-performing photovoltaics.
-
Demonstrate solar cells with over 95% performance retention for over 1,000 hours through automated, high-throughput experimentation and machine learning-assisted data analysis.
The findings are expected to guide the development of application-dependent encapsulation strategies to improve the lifetime of halide perovskite solar cells, contributing to the advancement of low-cost and stable solar energy technologies.
