Efficient charge generation and collection in organic solar cells based on low band gap dyad molecules

摘要

Low band gap dyad molecules were prepared that have absorption spectra matched well with the solar spectrum, and the construction of efficient charge transport pathways was observed. Under AM 1.5 illumination, the devices have achieved the highest Jsc (4.79 mA cm2) and FF (0.46) in dyad-based organic solar cells to date. Organic solar cells (OSCs) fabricated by solution processes using π-conjugated materials have attracted much attention as a renewable energy source, owing to their low fabrication cost,
