Manipulating the nanoscale morphology in the active layers of polymer solar cells

Abstract

A review. In the past decade, polymer solar cells (PSCs) have been rapidly developing and regarded as one of the most important research directions in the field of renewable energy and material sciences due to their potential applicability in flexible, lightwt., low-cost and/or transparent large-area devices. The morphol. of the active layers of polymer solar cells is an important aspect affecting its power conversion efficiency. In this review, the mol. design of the active layers and processing method (such as thermal annealing, additive, ternary solvent and green solvent) are introduced, and the future and key challenges of polymer solar cells are prospected.
