In the green energy wave, hydrogen fuel cells are hailed as the "ultimate energy solution," and the manufacturing quality of their core component – the bipolar plate – directly determines the cell's performance, lifespan, and safety.

Laser processing technologies, including ablation, engraving, and cutting, are fundamental to modern precision manufacturing. While they all utilize high-energy laser beams to interact with materials, they are distinguished by their core objectives, key process parameters, and resultant application scenarios. Understanding these differences is crucial for selecting the appropriate technology for specific industrial needs.

Laser ablation, a sophisticated material processing technology, has established itself as a cornerstone technique in precision marking and micro-fabrication. This process utilizes high-energy pulsed laser beams to selectively remove material from a surface through vaporization, achieving unparalleled accuracy in creating fine features and markings. As industries increasingly demand higher precision and minimal thermal impact, laser ablation continues to evolve, offering innovative solutions across various manufacturing sectors.

The printing industry is evolving with increasing demands for high-precision, high-efficiency, and environmentally friendlymanufacturing processes. Traditional mechanical scribing and chemical cleaning methodshave long been used, but the roll-to-roll (R2R) laser scribing & edge-cleaning systemis emerging as a disruptive technology.

Femtosecond laser processing represents one of the most advanced frontiers in precision manufacturing today. This technology utilizes laser pulses of incredibly short duration—approximately 10⁻¹⁵ seconds—to achieve material processing with unparalleled precision and minimal thermal damage. The unique characteristics of femtosecond lasers have opened up revolutionary possibilities across industries from medical devices to aerospace engineering.

The preparation of perovskite materials is a critical step in achieving high-efficiency perovskite solar cells. At the molecular scale, PbI₂ and CH₃NH₃I can rapidly react through self-assembly to form CH₃NH₃PbI₃. Thus, whether in solid, liquid, or gas phases, thorough mixing of the two raw materials can yield the desired perovskite material. However, for thin-film solar cell light-absorbing layers with thicknesses below 1 μm, the large perovskite crystals produced by solid-phase reaction methods are clearly unsuitable.
