The transition to renewable energy is accelerating, and perovskite solar cells (PSCs) stand at the forefront of next-generation photovoltaic technology due to their high efficiency potential and low-cost manufacturing. However, a significant bottleneck has been the scalable and precise patterning of large-area modules to ensure high performance and longevity.

The evolution of thin-film photovoltaic manufacturing increasingly relies on advanced laser processing technologies. Among these, ultrafast lasers, particularly picosecond and femtosecond systems, have emerged as transformative tools for structuring and optimizing solar cells based on materials like CIGS (Copper Indium Gallium Selenide) and perovskite. Their unique ability to deliver extreme precision with minimal thermal impact addresses critical challenges in processing these often-sensitive materials, directly contributing to enhanced device performance and longevity.

A major hurdle for perovskite solar cells has been the sensitivity of the materials to ambient air during manufacturing, which typically requires energy-intensive, inert-gas environments. A groundbreaking solution comes from Nanchang University, where researchers developed a novel "laser annealing" technique.

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 global PV market is entering a quality‑first, system‑value era: growth is broadening across regions, technologies are differentiating by efficiency and aesthetics, and the industry is consolidating around higher standards and smarter manufacturing. For Lecheng, aligning product roadmaps with these structural trends—especially in high‑efficiency cell and module testing—can unlock sustained share gains and long‑term customer value in both established and emerging markets.

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.

From December 21st to 22nd, the "5th Global Calcium Titanate and Tandem Battery (Suzhou) Industrialization Forum", jointly organized by the Shanghai Solar Energy Society, the Administrative Committee of Changshu Economic and Technological Development Zone, and the Photovoltaic Leader Innovation Forum, was successfully held in Changshu, Jiangsu.

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.
