Naphthalene diimide-based random terpolymer acceptors for constructing all-polymer solar cells with enhanced fill factors

Abstract

We developed two terpolymer acceptors based on N2200 through random copolymerization for all polymer solar cells with enhanced fill factors and photovoltaic performance.

Naphthalene diimide-based random terpolymers with axisymmetric and asymmetric electron acceptors for controllable morphology and enhanced fill factors in all-polymer solar cells

“…The morphology of the photoactive layer significantly influences the photovoltaic performance of all-PSCs. [63][64][65] To further understand the effect of partially substituted acceptors P(NDI-X10) on the morphology in the BHJ, the blend films were investigated using atomic force microscopy and transmission electron microscopy, and the results are shown in Fig. 4.…”
