Abstract Electrospun nanofibers combine high porosity, large specific surface area, and precisely tunable architectures, enabling superior charge transport, rapid response, and broad functional integration. Scalable electrospinning supports their deployment in organic thin-film devices, air filtration, humidity sensing, energy storage/conversion, thermal regulation, and biomedical engineering. Functionalization with nanoparticles or phase change materials further elevates performance in wearable devices, environmental monitoring, and personal thermal management. In biomedical contexts, electrospun polymeric fibers—natural or synthetic—promote wound repair, targeted therapeutics, and tissue regeneration, underscoring their transformative potential across disciplines. This review consolidates the recent advances in their specific applications in organic electronic, optoelectronic, and thermoelectric platforms, including organic field-effect transistors (OFETs), light-emitting diodes (OLEDs), photovoltaics (OPVs), and thermoelectrics (OTEs); in addition, polymer fiber fabrics from dry, wet, and melt spinning for these devices are also reviewed. Therefore, it is of great importance to develop high-performance electrospun nanofibers and fiber fabrics, and we aim to provide a complete picture of their recent developments. The unique properties of electrospun nanofibers and fiber fabrics in organic thin-film devices, regarding light-assisted current amplification (OFETs), electricity-to-light conversion (OLEDs), light-to-electricity conversion (OPVs), and heat-to-electricity conversion (OTEs), will be reviewed comprehensively. Their potential functionality in soft organic devices will be further illustrated.
