Abstract：Inthecontextof accelerated globalenergy transition，nano-thin-film solarcells，including organic photovoltaiccels（OPVs）and perovskitesolarcels（PSCs），have garnered widespread attention due totheirhighefficiency，low cost，and ease offabrication.Currently，the laboratory-recorded power conversion effciency（PCE）of single-junction OPVs has surpassed 20% ，while that of PSCs has exceeded 26% .This paper beginswith an overview of thestructures of OPVsand PSCs，summarizing the primary failure mechanisms of these cells，focusing on electrodes，charge transportlayers，and photoactivelayers.Subsequently，itoutlines commonmicrodefectimaging principlesand methods，including photoluminescence（PL），electroluminescence（EL），laserbeam-induced current imaging（LBIC），and lock-in thermography（LIT）.The paperreviews thelatest advancements in micro-defect imaging and the homogeneity research for OPVsand PSCs，highlights current limitations in micro-defect imaging，and suggests future development directions.This paper provides a comprehensive overview of the micro-defect imaging methods and applications for nano-thin-film solar cells.
