Development of π-Conjugated Materials for Efficient Organic Solar Cells

摘要

In this contribution, design and synthesis of various π-conjugated building unit based on naphthobisthiadiazole heteroaromatic ring are presented. These units are successfully incorporated into donor polymers and an acceptor molecule, which are found to have high π-π interactions to form well-ordered structures in the thin film. These materials therefore function well in organic photovoltaic cells. The structure-properties relationships are also discussed in depth.
