DuPont Photovoltaics Solutions, the industry leader in solar solutions that deliver proven power and lasting value for customers around the world, will introduce the newest innovation to its DuPont Solamet photovoltaic metallization paste at 2017 SNEC Photovoltaic Power Expo in Shanghai, 19-21 April. DuPontSolamet PV20A will be featured at DuPont’s highly engaging booth, W4-555, where participants can view products from the company’s portfolio of solar innovations that demonstrate the efficiency, reliability and return on investment enabled by DuPont materials.
Solamet PV20A is the company’s latest front-side silver paste designed specifically for P-type solar cells. Solamet PV20A is designed to be used in both Lightly Doped Emitter (LDE) and Passivated Emitter Rear Cell (PERC) solar cell construction. Solamet PV20A provides further aspect ratio improvement and superior contact, resulting in a more than 0.1 percent improvement in efficiency compared to other metallization pastes used by the industry. Solamet PV20A was developed to enable exceptional ultrafine line printing and contact performance with lower firing temperature, and is ideally suited to maximize efficiency for the most demanding conventional and PERC architectures while also ensuring reliable production performance.
DuPont Solamet new generation front side silver paste is already being used by several solar panel manufacturers, and two customer collaborations will be highlighted at DuPont’s booth to demonstrate how Solamet PV20A achieves increased efficiency and power output on mono- and multi-PERC modules. Taiwan Solar Energy Company (TSEC), which specializes in manufacturing high performance, top quality mono- and polycrystalline silicon solar cells and modules, will demonstrate how it has observed 21.15 percent cell efficiency and module power output as high as 305 Watts (60 pcs) in its V-Series mono PERC modules using Solamet PV20A. Another successful Solamet® PV20x adoption comes from REC, a leading vertically integrated solar energy company. The latest REC TwinPeak 2 Series, 60-cell multicrystalline solar panel, rated up to 295 Wp, deliver at least 20 Wp more per panel compared to standard 60-cell multicrystalline. The new heights are result from the combination of REC TwinPeak technologies and DuPont Solamet PV20x, which enables efficiency enhancement on multi PERC.
In addition to introducing Solamet PV20A, DuPont will highlight Solamet Interconnect Paste, an innovative new product development, designed with unique chemistry for PV applications as a replacement for traditional solder materials and adhesives. It enables advanced cell and module assembly with more flexibility and convenience in use. A shingled cell module assembled by Jinchen Solar Equipment using Solamet Interconnect Paste will be on display at DuPont’s booth. Also featured will be DuPont Tedlar PVF film, the only backsheet material proven to protect solar panels in the field for more than 30 years even in extreme conditions.
DuPont Photovoltaic Solutions is the leading supplier of specialty materials to the solar energy industry. Since 1975 more than half of the world’s 900 million installed solar panels contain DuPont materials.
