Time‐Resolved Photoluminescence Lifetime Measurements of Organic Photovoltaic Materials
physica status solidi (a), Volume 223, Issue 8, 22 April 2026.A nondestructive measurement technique utilizing time‐correlated single photon counting (TCSPC), based on photoluminescence statistics is presented for organic photovoltaic materials. This method identifies a comparative parameter independent of absorber layer thickness and the presence of transport layers (ETL/HTL).
