To discover the ideal perovskite material for solar cell application, a large parameter space (composition, surrounding condition, fabrication technique, etc.) must first be explored. Therefore, screening this parameter space using a rapid combinatorial screening approach can drastically speed up the rate of discovery. During the last decade, these discoveries and optimization processes of perovskite materials have been achieved using simple lab-scale deposition techniques and characterization methods, resulting in a substantial time-consuming process, slowing the rate of progress in the field of photovoltaics. Thus, the benefits of developing fully automated, high-throughput characterization techniques become apparent. Herein, a high-throughput solar cell testing system that enables parallel, real-time, and comprehensive measurements is detailed, allowing for 16 solar cells to be characterized simultaneously. The importance of measurement reproducibility, condition verification, and structured data postprocessing is shown.
