Abstract
Electronic skins and smart textiles are emerging applications integrating wearable displays, smart sensing systems, health-care monitors, and stretchable power systems. Although various deformable optoelectronic devices have been demonstrated, high-performance stretchable photovoltaic (PV) devices remain a significant challenge in device engineering and materials optimization. In this paper, we demonstrate how a ubiquitous material—3 M™ tape—can be used as a transparent substrate for highly efficient stretchable organic PV devices. Indeed, we constructed a stretchable OPV device displaying a power conversion efficiency (PCE) of 5.2% (under AM 1.5G 1000 W m−2)—the highest reported to date; in addition, this device retained 80% of its original PCE after 50 cycles of stretching at 20% strain. This study paves the way toward fully deformable OPVs for integration in wearable electronics. © 2017 Elsevier B.V.
