Leading PV module encapsulation and backsheet material supplier Hangzhou First Applied Materials Co, formerly First Photovoltaics (PV) reported a continued increase in demand with sales up by 16.56% but profits crashed by 43.49% on significant ASP pressure in the first half of 2017.
Agfa Specialty Products has introduced ‘UNIQOAT,’ its next generation of polyester-based backsheet product. UNIQOAT eliminates the risk of backsheet delamination as it is manufactured as a single layer backsheet and achieves a level of reflectivity. The new product was showcased at SNEC 2017.
DuPont, an industry leader in high-performance materials for photovoltaic panels, shares Bill of Materials (BoM) specification recommendations based on extensive field observations and laboratory testing.
The backsheet is the first barrier for ensuring the reliability and durability of PV modules for 25+ years. To reduce cost, backsheets with a variety of compositions and constructions have been developed and introduced in PV modules. For PV module manufacturers, a major challenge is choosing a low-cost backsheet that can maintain the current levels of high reliability and durability performance. In the work reported in this paper, the properties of several backsheets of various compositions and constructions were compared.
