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.

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.

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.

The manufacturing process of perovskite solar cells involves multiple precise steps, with laser technology playing a critical role in enhancing efficiency and stability. The key steps include: Substrate Preparation: Cleaning and pre-treating the substrate (e.g., glass or flexible polymers) to ensure optimal adhesion and conductivity. Electrode Deposition: Depositing transparent conductive oxides (e.g., ITO or FTO) as bottom electrodes.

Perovskite solar cells (PSCs) represent a transformative technology in photovoltaics, with industrialization accelerating globally. Unlike traditional silicon-based cells, PSCs require entirely new production processes and equipment, creating significant investment opportunities in specialized manufacturing tools. The core equipment includes coating, deposition, laser, and encapsulation systems, with laser etching and thin-film deposition being particularly critical for scalable production.

In July 2024, Yangzhou hosted the 7th Global Perovskite & Tandem Cell (Yangtze River Delta) Industrialization Forum, a pivotal summit gathering global experts, investors, and industry leaders to address “Breaking Industrialization Bottlenecks, Building a New Energy Future.” As a leading Chinese supplier of perovskite laser equipment, Lechen Intelligence stood out, winning the “2024 Most Influential Perovskite Laser Equipment Enterprise” award. Its CEO, He Le, delivered a keynote speech highlighting breakthroughs in laser technology, showcasing China’s strength in high-end new energy equipment.

YANGZHOU, Nov. 23 — At 20:18 tonight, Dehu Perovskite Research Institute's 100MW pilot production platform (1.2m×0.6m substrate) achieved first-light milestone in its Yangzhou industrial park. This breakthrough, 22 days ahead of schedule, marks a quantum leap in perovskite industrialization.
