A molecular interaction-diffusion framework for predicting organic solar cell stability

Masoud Ghasemi et al.

Summary: The diffusion of NF-SMA into the donor polymer exhibits Arrhenius behavior, with the activation energy linearly scaling with the enthalpic interaction parameters between the two materials. The most thermodynamically unstable systems are the most kinetically stabilized.

Achieving over 17% efficiency of ternary all-polymer solar cells with two well-compatible polymer acceptors

Rui Sun et al.

Summary: The study focuses on developing high-performance all-polymer solar cells by designing a novel polymer acceptor PY2F-T and enhancing efficiency through ternary blend with PYT in the PM6: PY2F-T host system. This approach significantly improves power conversion efficiency and stability, marking a promising future for the application of all-PSCs.
