Efficient and stable organic solar cells enabled by multicomponent photoactive layer based on one-pot polymerization.

Abstract in brief

• The study addresses the challenge of degradation in organic solar cells (OSCs) by creating a thermally stable multicomponent photoactive layer through a simple one-pot polymerization process.
• This new layer achieves a high power conversion efficiency of 11.8% while maintaining over 80% of its initial efficiency for more than 1000 hours, showcasing a strong balance between efficiency and durability.
• The research highlights the importance of specific block polymers in maintaining stable film morphology and effective charge transport during long operation periods, which could lead to more affordable and reliable solar cell technology.
