Measurement example of perovskite material | ODPL measurement system

 

Similar to semiconductor crystals, we have succeeded with perovskite crystals to calculate IQE from ODPL measurement by utilizing the property of these crystals to only make green light emission upwards. As a result of this, IQE reached at least 62.5 %, and we found IQE fluctuates greatly depending on whether methylammonium ions are excessive or deficient.
