In the manufacturing of thin-film solar cells, such as perovskite cells, laser scribing (P1, P2, P3) and edge cleaning (P4) are critical processes that directly impact cell efficiency and production yield. Multi-beam synchronous processing technology stands as a pivotal innovation for enhancing manufacturing efficiency. LeCheng Intelligent, a leader in this field, achieves high-precision, high-throughput processing of large-area panels through advanced optical design, sophisticated motion control, and deep process integration.

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.

Recently,Lecheng Intelligence Technology (Suzhou) Co., Ltd. (hereinafter referred to as "Leco Smart") has received angel - round strategic investment from Shanghai DEK Print - Coating Equipment Co., Ltd. The funds from this round of financing will be mainly used for technology research and development, renovation of production sites, and procurement of testing equipment.

The rapid growth of flexible electronics—including flexible printed circuit boards (FPCs), organic light-emitting diodes (OLEDs), wearable sensors, and rollable displays—has driven demand for high-precision, high-throughput manufacturing solutions. Among these, the roll-to-roll (R2R) laser scribing & edge-cleaning systemhas emerged as a transformative technology, enabling non-contact, high-speed processingof thin, delicate materials.

As consumer electronics continue to evolve toward thinner, lighter, and more miniaturized designs, the demand for ultra-precise and efficient manufacturing processeshas never been greater. Laser drilling technologyhas emerged as a critical enabler in this transformation, allowing manufacturers to create micro-sized holesin materials like PCBs, glass, and flexible substrateswith unprecedented accuracy.

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.

First, why can perovskite solar cells still generate electricity indoors or in low-light environments? It's not generating light itself, but rather converting the faint light into electrical energy, which powers the small light in the circuit. Perovskite material is particularly good at absorbing light; even indoor light or scattered light can be utilized efficiently and normally.

As wearable technology advances from fitness trackers to medical monitors and augmented reality glasses, power autonomy remains the critical bottleneck. Conventional batteries limit device functionality and design freedom, while rigid solar solutions compromise wearability. Enter ultrathin all-perovskite photovoltaic cells – the breakthrough technology enabling truly self-sustaining wearable ecosystems.

The P1, P2, and P3 laser scribing processes each play distinct but interconnected roles in manufacturing high-efficiency thin-film solar cells. P1 establishes the foundational electrical isolation, P2 creates the critical series interconnection between cells, and P3 completes the circuit isolation. Together, these precision processes enable the production of series-connected solar modules with minimized dead areas and maximized active area for power generation. As solar cell technologies continue to advance toward higher efficiencies and thinner layer architectures, the precision and control offered by laser scribing will remain indispensable for commercial viability.

In the realm of advanced laser technology, ultrafast lasers have revolutionized precision manufacturing, medical procedures, and scientific research. Among these, picosecond and femtosecond lasers represent the cutting edge of ultrashort pulse technology. While both operate at timescales incomprehensibly fast to humans, the subtle differences between them significantly impact their applications and effectiveness. This technical comparison examines the fundamental characteristics, mechanisms, and practical considerations of these two laser technologies.
