About
Zhengwei Xu is a pioneering researcher in the field of perovskite photovoltaics, with a particular focus on understanding and improving material stability through high-throughput experimentation and machine learning. His most impactful work, "Discovery of temperature-induced stability reversal in perovskites using high-throughput robotic learning" (174 citations), fundamentally challenged conventional wisdom by demonstrating that the stability ranking of different cations in perovskites can reverse depending on the testing temperature. This finding, achieved through an innovative combination of robotic synthesis and data-driven analysis, revealed that accelerated aging tests at high temperatures (e.g., 140°C) may not accurately predict performance under real-world operating conditions. Xu’s contributions have reshaped how the research community approaches stability testing, emphasizing the need for temperature-appropriate evaluation protocols. His work exemplifies the power of integrating automation and machine learning to uncover non-intuitive material behaviors, making him a leading voice in the quest for durable, commercially viable perovskite solar cells.
