Abstract

Organic photoconversion devices such as organic photovoltaic (OPV) and photodetectors (OPD) are attracting significant attention due to their potential to be lightweight, flexible, non-toxic, and compatible with large-scale manufacturing. In particular, the development of the new small molecule-based non-fullerene acceptors (NFAs) has enabled OPVs to show remarkable improvements in device efficiency. Although promising, there is still a lack of clear understanding of the impact of molecular structure and orientation of NFAs on photophysical processes critical for device performance.
