Key Points

Identify molecular design and device engineering strategies capable of advancing organic photovoltaic power conversion efficiencies beyond the 19% threshold.
Assessed donor-acceptor molecular structures, focusing on non-fullerene acceptors with optimized bandgaps.
Evaluated morphological control and interface optimization techniques that minimize non-radiative energy losses.
Demonstrated that balancing optical absorption, charge carrier mobility, and exciton dissociation is critical to surpass 19% efficiency.
Identified suppression of non-radiative recombination as the primary pathway to elevate open-circuit voltages without sacrificing short-circuit current.
