Prolonging Exciton Diffusion Length via Modulating Aggregation Structures for Binary Organic Photovoltaics Approaching 20% Certified Efficiency
{{output}}
The performance of flexible all-polymer organic photovoltaics (OPVs) constrained by low short-circuit current density (JSC) and fill factor (FF), resulting in diminished power conversion efficiency (PCE) and compromised mechanical stability. Enhancing the exci... ...
