All-Polymer Solar Cells and Photodetectors with Improved Stability Enabled by Terpolymers Containing Antioxidant Side Chains.

Abstract in brief

• This research focuses on developing special types of polymers called terpolymers that include antioxidant side chains, like BHT, to improve the long-term and light stability of organic solar cells and photodetectors.
• The study shows that adding benzothiadiazole (BT) to these terpolymers doesn't negatively affect their basic properties but significantly enhances their stability under sunlight, leading to better device performance and longer lifespan.
• Solar cells and photodetectors made with these BHT-containing terpolymers achieved higher efficiency and showed less degradation over time, demonstrating a promising approach to making more durable organic electronic devices.]
