Efficient ternary all-polymer solar cells with PCE up to 9.03 percent
Analogue polymers possess very similar chemical structure and matched energy levels to form the cascade of the co-donors. Benefiting from those analogous polymer structures, there is little influence of the morphology in blend film compared to their pristine polymer films. The ternary all-PSCs have more balanced charge mobility and prolonged carrier lifetime compared to the binary devices. The champion ternary all-PSCs obtain a high PCE of 9.03 percent, 10 percent enhancement compared to that of binary device. (2018-12-05)
