BTP-4F

Description

Y6 uses an electron-deficient molecular core to obtain a low bandgap NFA with an improved electron affinity. OPV devices made from Y6 can reach exceptionally high performances in single-junction devices, with a maximum PCE reported of 15.7% (14.9% certified by ENLI Tech Laboratory). Y6 is versatile and can be employed in both conventional and inverted OPV device architectures and can maintain a high PCE with varying active layer thicknesses (13.6% in thick 300 nm layers).
