The International Solar Energy Industry and Photovoltaic Engineering (Shanghai) Exhibition & Conference (SNEC) will be held in Shanghai, China from May 20th to 22nd. DEK Solar will be exhibiting several new metallization platform technologies during the exhibition to fully Reflecting its superior ability to improve solar cell efficiency and production line throughput. At DE3-320, DEK Solar's award-winning metallization platform will be at the heart of this show. Each technology is designed to meet the unique needs of DEK customers. DEK Solar's metallization system utilizes exceptional precision, low fragment rates, and adjustable wph capabilities to meet the specific needs of solar cell manufacturing specialists. The DEK platform from DEK Solar not only covers a small area but also processes 1,350 wafers per hour. The system is highly reliable and future-proof and scalable enough to meet the needs of today's PV companies. At the same time, the Houyi platform optimizes reliable metallization with robust machine control software and advanced sensing technology. The new blade mechanism supports blade and diamond blade design, proven by thousands of print passes, and its excellent print quality. In addition, the integrated air knife technology minimizes platen area contamination, helping to reduce wafer breakage. In addition to the above outstanding performance, its simple scalability can better meet the future development needs. And these have prompted Houyi to become an ideal platform for commercial solar cell production at all levels. DEK Solar's high-volume Eclipse metallization platform has 4,000 wph of production capacity and combines high speed, accuracy and reliability. At the heart of Eclipse's market value is its highly flexible and modular design, as dynamic solar cell manufacturing leverages the modularity of the platform to make production easy and convenient where demand has a decisive impact Upgrade to raise 1,200 wph to 4,000 wph. The print speed of 600 millimeters per second, combined with battery transfer at zero-edge contact, guarantees high productivity and lowest chip rate. Also on display at SNEC 2014 will be the Apollo metallization platform from DEK Solar, which combines the new solar Sentinel technology. The award-winning Apollo platform achieves 2 Cpk +/- 10 μm accuracy with fragmentation rates below 0.15%. Combining this technology with DEK Solar's new Sentinel further enhances the Apollo platform's productivity. Solar Sentinel is a new inspection technology that validates the material coverage of 45 μm fine grid lines, detects battery edge gaps and senses broken silicon. The "over / under" inspection feature makes a pass or fail judgment on the integrity of the printing and wafers in real time to maximize throughput while ensuring yield loss is minimal. "High-precision, scalable platform technology increases the efficiency of battery production and field performance, which is critical for the cost-competitive solar cell manufacturing," commented Brian Lau, director of solar energy at DEK. However, progress in photovoltaic cell manufacturing does not depend solely on the performance of the printing platform, and DEK Solar's next generation screen and stencil development is driving the world's most efficient production of batteries - a team of metallization process specialists promote." Not long ago, DEK solar and the Hamelin Solar Institute (ISFH) co-founded the back-passivation solar cell efficiency of 21.2% of the record. During the SNEC show, DEK Solar will share with the spectators at the show excellent technologies to help boost this record, including two-step process screens and VectorGuard (VG) fine grid lines. DEK Solar's VG fine grid lines have a uniform gate line with a high area ratio and a uniform raster line width of less than 40 μm. In the two-step printing process, the main grid is first screen printed, followed by the VG stencil printed conductive fine grid lines. This not only reduces the consumption of silver paste, but also helps to improve battery efficiency. This is confirmed by the latest record in the world, co-founded by DEK solar and the Hamelin Solar Institute. DEK Solar's VG Fine Grid Wire Mesh utilizes VectorGuard steel mesh technology, which has won numerous industry awards using a single steel grid design with foil replacement for maximum flexibility. Inherent advantages of the VectorGuard system include reduced storage requirements by simply storing the characteristics of the foil, promoting environmental protection by eliminating disposal or refurbishment of the steel truss, and better printing performance. The VG fine grid wire mesh for solar cell printing, its unique tensioning mechanism to improve the printing behavior, and to limit the widening of the external raster to ensure the uniformity of silver paste and outstanding fine grid lines. DEK Solar will demonstrate VectorGuard technology at its booth throughout the show. "This is an exciting time for DEK Solar," concludes Lau. "We are constantly innovating and investing in this challenging market environment and with this show we want to invite SNEC's audience to witness the successes we have achieved that will further promote more cost-effective and efficient solar energy Battery manufacturing.
