Annotatsiya
A non-fullerene acceptor with a high relative dielectric constant (<italic>ε</italic><sub>r</sub>) over 9 is developed. It offers an efficiency of 8.5%, which is the best result for organic solar cells employing high <italic>ε</italic><sub>r</sub> materials. Further research should focus on morphology optimization to make high <italic>ε</italic><sub>r</sub> practically useful in devices.
