Due to the optimized stacking mode and good blend miscibility, PBDFCl‐2‐based device exhibitsa more elegant power conversion efficiency (PCE) of 17.00% compared to PBDFCl‐1‐based device. The more twisted side chains conformation not only achieve the control of moderate molecular weight for PBDFCl‐2, but also easily form molecular stacking through adopting BDF unit and maintain sufficient polymeric crystallinity. Herein, a strategy of steric effect is applied to benzodifuran (BDF)‐based polymer by introducing different positions of Cl atom, producing two polymers PBDFCl‐1 and PBDFCl‐2. However, the high molecular weight need to subtly control the reaction time and state, inevitably caused batch‐to‐batch variations. To obtain high photovoltaic performance, adopting polymers with high molecular weight as donors is an ordinary strategy. With the development of organic solar cells (OSCs), the high‐performance and stable batch variance are becoming a new challenge for designing polymer donors. More importantly, the “end‐capped” ternary strategy enables efficient and facile improvement of all‐PSCs performance without additional selection and complicated synthesis for the third component.

The ternary devices also exhibit improved stability, outstanding tolerance of active layer thickness, and high performance of 1 cm² unit cells. The PM6:PM6TPO:PY‐IT based ternary devices exhibit impressive PCE of 17.0% with enhanced light absorption and optimal morphology, and the introduction of PM6TPO significantly reduces the phase separation. In this research, an “end‐capped” ternary strategy is proposed by introducing PM6TPO as a third component to fabricate highly efficient all‐PSCs. However, the power conversion efficiency (PCE) of all‐PSCs still lags behind the polymer‐donor‐small‐molecule‐acceptor based organic solar cells, owing to the excessive phase separation with poor miscibility between polymer donor and acceptor. Special intracavity thermal compensation technology and harmonic conversion technology realize efficient and stable frequency multiplication conversion.Recently, all‐polymer solar cells (all‐PSCs) have received increasing attention and made tremendous progress.

MQ series ultraviolet laser marking machine is used in the high-end market of ultra-fine processing, perfect cutting and micro-processing.

The MQ-M sub-series uses DXT Laser’s pulsed ultraviolet laser source. Ultraviolet light focusing spot is very small, processing heat-affected zone is very small and it is more suitable for ultra-fine marking of various materials. The material has a high absorption rate of ultraviolet light and has a wider range of material adaptability.
