Manz has significantly enhanced its PERC solar cell production technology, reinforcing its position as a leading provider of professional solar manufacturing solutions. With 25 years of experience in the solar industry, Manz has built strong relationships with major battery manufacturers worldwide, solidifying its reputation as a trusted partner in innovation and efficiency.
To meet the growing global demand for high-efficiency, low-cost solar cells, Manz Technology, a top-tier high-tech equipment manufacturer, introduced an advanced cSi solar cell production solution that achieves a remarkable conversion efficiency of 20.5%. This breakthrough not only optimizes crystalline silicon solar cell production but also strengthens Manz’s leadership in the industry. The company will showcase its latest innovations at the SNEC PV POWER EXPO in Shanghai from May 20 to 22, 2014, highlighting its commitment to driving the future of solar energy.
Manz’s next-generation production process integrates the VCS 1200 Plasma-Assisted Chemical Vapor Deposition (PECVD) system, which deposits an alumina passivation layer on the back of the cell, combined with the LAS 2400 laser hole opening technology. This combination enables large-scale, high-efficiency production of crystalline silicon solar cells while minimizing the total cost of ownership. Compared to other systems on the market, Manz’s fully automated, easy-to-maintain equipment is more compact and efficient, making it ideal for both monocrystalline and polycrystalline applications. Manz provides comprehensive equipment and process technologies to help customers upgrade their existing production lines to produce more efficient PERC batteries.
The VCS 1200 system features a vertical process design with a throughput of up to 1,200 wafers per hour. Its advanced plasma and carrier systems ensure uniform coating without defects or edge deposits, offering a significant technological advantage over many competitors. Additionally, the system allows for one-sided PECVD deposition without unwanted side effects, ensuring excellent reproducibility and industry-leading solar cell performance. The rapid cleaning concept minimizes downtime, and the system can be easily integrated into existing lines, delivering the lowest cost of ownership for front- and back-side coating and carrier cleaning.
Complementing the VCS 1200 is the LAS 2400 laser opening system, designed for precise and efficient electrode opening on the backside passivation layer. This modular, compact system offers high output—up to 2,400 wafers per hour—with an opening width ranging from 30 to 100 micrometers. It ensures safe wafer handling and reduces breakage rates, making it an ideal solution for upgrading current production lines. Together, the VCS 1200 and LAS 2400 systems enable PERC solar cells to achieve a record efficiency of 20.5%.
In addition, Manz offers the IPSG CEI 4800 wet chemical processing tool, which works seamlessly with the VCS 1200 and LAS 2400 systems to create a complete technical solution. The IPSG CEI 4800 is used for removing heavily doped layers and phosphosilicate glass (PSG) from silicon wafers, ensuring clean surfaces for subsequent processes. Its soft sponge roller and minimal pressure design help reduce wafer fragmentation, enhancing overall yield and quality.
Dieter Manz, CEO and founder of Manz Group, emphasized the importance of the Chinese market: “China is the world’s largest solar producer and consumer, and we are proud to support its growth. With 25 years of expertise, our solutions have been adopted by leading manufacturers globally. At SNEC 2014, we showcased our latest advancements, demonstrating our commitment to innovation and customer success.â€
Manz has deepened its presence in China, establishing a 20,000-square-meter production base in Suzhou in 2012. Currently, the company employs approximately 900 people across Asia, with nearly half being local staff. Manz continues to invest in the region, working closely with partners to improve the efficiency and cost-effectiveness of their solar cell production lines.
In the photovoltaic industry, Manz focuses on crystalline silicon solar cell production and thin-film module solutions. It provides metallization, laser processing, wet chemical processing, vacuum coating, automation, and testing & inspection technologies, ensuring end-to-end support for its clients.
