Summary: This study investigates the effects of electron transport layer (ETL) thickness on light extraction in corrugated organic light-emitting diodes (OLEDs). The results show that light extraction in corrugated OLEDs significantly depends on the ETL thickness. Changing the ETL thickness alters the distribution of carrier recombination and results in different attribution of optical loss modes in OLEDs, leading to variations in light extraction and device efficiency.
