Lecheng Intelligent's laser wire-feed welding technology represents a significant advancement in thermal management manufacturing. By combining precision engineering with robust process control, Lecheng enables the production of high-performance heat sinks that meet the demanding requirements of modern power electronics. As industries continue to push the boundaries of power density and efficiency, this technology will play an increasingly important role in ensuring the reliability and longevity of electronic systems across automotive, telecommunications, and industrial applications.

In the race to commercialize high-efficiency perovskite solar modules, precision laser processing is not merely an optional manufacturing step; it is a fundamental enabler. By minimizing dead zones, preserving material integrity with ultra-low thermal impact, and ensuring reproducibility across large areas, companies like Lecheng Intelligent are providing the essential tools to unlock the full potential of this promising technology. The path to higher module efficiency is, quite literally, being carved by laser light.

Lecheng Intelligent’s roll-to-round laser systems are revolutionizing how wearables harvest energy—transforming sunlight into a seamless power source that enhances device longevity, user convenience, and sustainability. By bridging high-precision manufacturing with real-world usability, they pave the way for a future where electronics are truly wireless and self-sufficient.

Lecheng Intelligent’s laser innovations are bridging the gap between lab-scale solar technology and mass-market applications. By enabling efficient, flexible, and durable perovskite cells, they are empowering a future where energy generation is integrated into the fabric of our lives—making sustainability portable, accessible, and inevitable.

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 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) 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%).
