Abstract

The invention relates to a patterned transparent back plate material which consists of a pattern layer, an adhesive layer, a substrate layer and a weather resistant layer in sequence, wherein the pattern layer has good reflection properties in visible light-near infrared areas of 400-1200nm and faces to the side of a battery piece when being used. Due to integration of good light permeability andgood reflection, a transparent back plate made of the patterned transparent back plate material is excellent in comprehensive property such as long-term weather resistance, adhesiveness and insulation. The patterned transparent back plate material is novel in design, simple in preparation process, easy to operate and excellent in product performance, an effective power gain effect is provided fordouble-side power generation crystalline silicon photovoltaic modules, a base is made for cost optimization of a crystalline silicon photovoltaic back plate material, and meanwhile long-term outdoor use reliability of the photovoltaic modules is powerfully ensured.

Description

technical field

[0001] The invention belongs to the field of photovoltaic encapsulation materials, in particular to a transparent backboard material. Background technique

[0002] In recent years, new energy has become the general trend, among which solar energy is inexhaustible and inexhaustible, which has become the focus of new energy development. According to the "Letter on Soliciting Opinions on the Construction Scale of Photovoltaic Power Generation in 2013 and 2014", the construction scale of photovoltaic power generation increased by 20% in 2014, reaching 12GW, of which 8GW is distributed photovoltaic, and its industrial scale can reach 1.2 trillion yuan, one trillion Yuan's industry is gradually taking shape, and its development potential is huge. The "Notice of the General Division of the National Energy Administration on Doing a Good Job in the Preparation of the 13th Five-Year Plan for Solar Energy Development" mentioned that solar energy resources are abundant,...
