研究目的
Investigating the influence of chlorination on the photovoltaic performance of small molecular acceptors in polymer solar cells.
研究成果
Incorporating chlorine atom into the conjugated side chains of SMAs is an effective strategy for designing high-performance non-fullerene acceptors, leading to improved photovoltaic performance in polymer solar cells.
研究不足
The study focuses on the impact of chlorination on SMAs' properties and device performance, but does not explore the long-term stability under operational conditions or the scalability of the fabrication process.
1：Experimental Design and Method Selection:
Designed and synthesized SMAs BTC-2F and BTH-2F based on CBT core with chlorinated-thienyl and thienyl conjugated side chains, respectively. Selected PM6 as the donor material for bulk heterojunction polymer solar cells processed with toluene.
2：Sample Selection and Data Sources:
Used PM6 as the donor material and BTC-2F/BTH-2F as acceptors.
3：List of Experimental Equipment and Materials:
Utilized instruments for UV-vis absorption spectroscopy, cyclic voltammetry, and photovoltaic device fabrication.
4：Experimental Procedures and Operational Workflow:
Fabricated inverted structure devices with glass/ITO/ZnO-gel/PFN/PM6:Acceptor/MoO3/Al configuration. Optimized donor:acceptor ratio, process additive, and thermal annealing temperature.
5：Data Analysis Methods:
Analyzed device performance using current density-voltage characteristics and external quantum efficiencies spectra.
