Bithiazole-based A-π-A'-π-A-type completely non-fused small-molecule acceptors for efficient organic solar cells

Key Points

• The aim is to engineer entirely non-fused small-molecule acceptors for improved organic solar cell performance.
• Designed and synthesized bithiazole-based small-molecule acceptors.
• Modified terminal groups and side chains of the acceptors.
• Evaluated the efficiency of the organic solar cells using these acceptors.
• Achieved higher efficiency compared to traditional acceptors.
• Demonstrated effective light absorption and charge transport in the new acceptors.
