Addressing IV Characterization Challenges for Commercial Perovskite Modules

Perovskite solar modules are rapidly transitioning from the lab to commercial production, with gigawatt-scale factories and the first field-deployed solar projects underway. Impressive efficiencies have been achieved with record single-junction perovskite devices achieving over 26% and perovskite-silicon tandem devices exceeding 34%. However, their successful upscaling relies on overcoming key challenges: 1) ensuring long-term stability and reliability, and 2) developing rapid and accurate methods for stabilized power measurements. Determining the stabilized power output (SPO) of perovskite devices presents significant challenges due to complex degradation and stabilization behaviors. Industry standards are evolving towards stabilization protocols incorporating MPP tracking or asymptotic IV measurements, light-dark cycles, and temperature variations. These protocols require extensive testing of many hours to assess device stability which is impractical for inline characterization. This work will explore strategies to accelerate performance assessment including reviewing limitations of current IV characterization techniques, exploring emerging measurement protocols, and discussing the integration of rapid and reliable IV characterization techniques into perovskite (tandem) module production lines. By addressing these challenges, we aim to facilitate the rapid development and commercialization of high-performance and reliable perovskite solar modules.
