The "SNEC 18th (2025) International Photovoltaic and Smart Energy Conference & Exhibition (Shanghai)" was grandly held at the National Exhibition and Convention Center in Shanghai from June 11 to 13, 2025. As one of the world's largest and most influential photovoltaic events, it attracted thousands of companies from all over the world to participate. It provided an excellent platform for technical exchanges, product displays, and market expansion within the photovoltaic industry.

"Shenzhen Lianpeng" showcased its newly developed "Perovskite Coating Machine + VCD + HP" equipment at the exhibition. This equipment supports coating on substrates up to 2.4 meters wide (a relatively rare size among similar devices in the industry), attracting many professionals in the field to stop by for visits and exchanges.

As a new generation of photovoltaic technology, perovskite solar cells boast advantages such as high photoelectric conversion efficiency, low cost, and simple preparation processes, positioning them as the main force in future photovoltaic markets.

Shenzhen Lianpeng's "Perovskite Coater" is a masterpiece meticulously crafted over many years by "Liansu Equipment", aligning with the nation's dual-carbon strategy. It focuses on green, environmentally friendly, and low-carbon equipment.

As core equipment for the preparation of perovskite solar cells, Shenzhen Lianpeng's "Perovskite Coater" employs slot-die coating technology. By precisely controlling the coating speed and thickness, it evenly applies perovskite solution onto conductive substrates to form high-quality photoelectric films. The mainstream equipment supports production capacities from laboratory scale to gigawatt levels, suitable for single-junction and tandem cell productions, and features auxiliary functions like vacuum adsorption and heating. These coaters are widely applied in scenarios such as photovoltaic power stations and building-integrated photovoltaics (BIPV).

Shenzhen Lianpeng's "VCD Vacuum Chamber Drying Equipment" is designed for controlled curing after the film coating process of perovskite solutions. By precisely regulating temperature, pressure, and flow field design, it achieves uniform drying of the films, enhancing the crystalline quality and stability of perovskites. This equipment is one of the key process devices in the preparation of perovskite solar cells, especially suitable for large-area production.

Shenzhen Lianpeng's "HP product line" mainly refers to thermal compression related equipment and processes, including thermal compression encapsulation machines and annealing furnaces. The thermal compression encapsulation machine achieves efficient encapsulation of perovskite devices through precise temperature control (using a full copper heating platform) and uniform pressure application, in conjunction with materials such as butyl rubber/POE, solving the problem of sensitivity to water and oxygen. The annealing furnace utilizes hot air circulation technology for passivation layer annealing crystallization, supporting multi-layer curing to enhance film performance. Additionally, high-temperature thermal compression processes can also assist in the recrystallization of perovskite thin films, improving grain structure, and enhancing device efficiency and stability.

In addition to advanced technology, the reliability and stability of Shenzhen Lianpeng's "Perovskite Coating Machine + VCD + HP" equipment have been thoroughly validated. During the R&D process, Shenzhen Lianpeng's technical team conducted countless experiments and tests, optimizing and improving every component and system of the equipment to ensure it can operate stably for long periods in complex production environments.

Key components of the equipment are selected from high-quality materials and well-known brands, undergoing rigorous quality testing and screening to guarantee their performance and reliability. Furthermore, Shenzhen Lianpeng employs a stringent quality management system during production, monitoring the entire manufacturing process and ensuring quality control for each piece of equipment, so that every unit delivered to customers meets high-standard quality requirements.

At the exhibition site, Shenzhen Lianpeng demonstrated the impressive capabilities of its equipment through live demonstrations. Operating continuously for several hours without interruption, the equipment maintained efficient and precise working conditions, with all performance metrics meeting or exceeding industry standards. The stable operation and reliable performance earned unanimous praise from both the audience and clients on-site.
