Molecular interactions that drive morphological and mechanical stabilities in organic solar cells

Salma Siddika et al.

Summary: By studying high-performance polymers and small molecule acceptors, the relationship between the morphological stability and mechanical stability of organic solar cells (OSCs) is investigated. The heterointeraction between polymers and small molecule acceptors is found to play a crucial role in film toughness, while the small molecule acceptors drive the embrittlement and diffusion characteristics in the blend films.

Versatile methods for improving the mechanical properties of fullerene and non-fullerene bulk heterojunction layers to enable stretchable organic solar cells

Emilie Dauzon et al.

Summary: This study develops and evaluates two techniques to enhance the mechanical resistance and stretchability of bulk heterojunction active layers in organic solar cells without compromising photovoltaic performance. The addition of a cross-linker improves the power conversion efficiency by inducing increased aggregation of P3HT. On the other hand, the addition of elastomers acts as a mechanical softener, with SEBS elastomer showing excellent compatibility with various blend systems. The versatility and scalability of these approaches highlight their potential in manufacturing high-performance solar cells.

Achieving 19% Power Conversion Efficiency in Planar-Mixed Heterojunction Organic Solar Cells Using a Pseudosymmetric Electron Acceptor

Wei Gao et al.

Summary: By adopting the asymmetric selenium substitution strategy and using a pseudosymmetric electron acceptor, the power conversion efficiency of planar-mixed heterojunction organic solar cells (PMHJ OSCs) can be significantly improved. The increased dielectric constant and improved dimer packing lead to lower exciton binding energy, more efficient exciton dissociation, and reduced radiative recombination loss. These findings provide an effective way to develop highly efficient acceptor materials for OSCs.

Donor-Acceptor Alternating Copolymer Compatibilizers for Thermally Stable, Mechanically Robust, and High-Performance Organic Solar Cells

Jin-Woo Lee et al.

Summary: The study demonstrates the use of donor-acceptor alternating copolymer-type compatibilizers (DACCs) in high-performance SMA-based organic solar cells to enhance their power conversion efficiency, thermal stability, and mechanical robustness. Addition of DACCs effectively reduces interfacial tensions and stabilizes interfaces in polymer donor (P-D)-SMA blends, resulting in desired morphologies with exceptional thermal stability and mechanical robustness. OSCs with 20 wt % DACCs exhibit excellent morphological stability, retaining over 95% of initial power conversion efficiency after 300 hours at elevated temperature, contrasting with control OSCs without DACCs which degraded rapidly.
