System for Automated Performance Assessment of Perovskite-based Optoelectronic Devices (No. 104)

Summary

A novel system for assessing the performance and quality of perovskite used in solar cells or other semiconductor devices.

The global perovskite market size is over 450 million USD and is expected to grow at a CAGR of 30.8%. Perovskites are at the forefront of materials research because of their wide range of potential applications including solar cells, LED lights, display screens, memory devices (RAM), lasers, batteries and photodetectors. To ensure perovskite-based devices are of high quality and have optimized Power Conversion Efficiency (PCE), performance evaluations need to be conducted. However, perovskite has problems with current-voltage (I-V) hysteresis when measured by scanning voltage. Such hysteresis effects give rise to concerns revolving around the quality and accuracy of reported efficiency values in the past, thereby to the need for better practices than conventional ones for measuring and reporting perovskite quality and performances. Here, we present a promising performance assessment system developed by a group of researchers led by Prof. Yabing Qi. The developed system provides a fully automated and reliable measurements of perovskite quality and PCE.
