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.

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 journey of perovskite solar cells is moving decisively from the lab to the landscape. The discovery of their seasonal personality is not a setback but a critical step forward. By using advanced MPPT analysis to decode the messages hidden in winter's performance dip, scientists and engineers are gaining the knowledge needed to formulate more robust materials, optimize device architectures, and finally design perovskite solar cells that don’t just boast a record efficiency on a perfect day, but deliver reliable, clean energy all year round.

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 structure of perovskite solar cells is illustrated in the figure below. Its core is a light-absorbing material composed of organometal halides with a perovskite crystal structure (ABX₃) (unit cell structure shown in the attached figure). In this perovskite ABX₃ structure, A is the methylammonium group (CH₃NH₃⁺), B is a metal lead atom, and X is a halogen atom such as chlorine, bromine, or iodine.

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.

Perovskite solar cells (PSCs) have achieved a power conversion efficiency (PCE) of up to 26.95% under standard test conditions (STC). The current research focus has shifted from efficiency improvement to scalability and stability enhancement. Based on four years of outdoor data from Berlin, this study reveals significant seasonal performance fluctuations in PSCs: stable performance in summer but a substantial decline in winter (up to 30%).
