The steady-state versus pulsed light debate in perovskite testing is not about finding a single "correct" method, but about applying the right tool for the right question. Pulsed light offers speed and insight into intrinsic electronic properties, while steady-state testing delivers the essential truth about operational performance and long-term energy yield. For the perovskite industry to build trust and achieve commercialization, prioritizing steady-state measurements as the gold standard for reporting stabilized efficiency and conducting reliability assessments is non-negotiable. Ultimately, investing in precise, reliable testing equipment for both methodologies—and understanding their distinct roles—is crucial for transforming promising perovskite innovations into bankable, high-performance solar products that can endure in the real world.
