Abstract

The invention discloses a POE composite back material for photovoltaic assembly packaging. The back material comprises a transparent POE film, a non-light-transmitting POE film and a fluorine film. The transparent POE film is formed by 95% of POE resin and 5% of property-modifying additives; and the non-light-transmitting POE film includes 80 to 85% of POE resin, 10 to 15% of barrier and enhancement materials, and 5% of property-modifying additives. The non-light-transmitting POE film can be white, gray or black. The provided POE composite back material having excellent performances meet the back material requirements and has important significance in the solar industry and the broad application prospects.

Description

technical field

[0001] The invention belongs to the field of solar photovoltaic modules, and in particular relates to a POE composite back material for packaging photovoltaic modules. Background technique

[0002] With the increasing cost of carbon in the future, it is an inevitable trend to replace traditional fossil energy with new energy represented by solar energy. At present, the governments of various countries have increased investment in the solar photovoltaic industry in terms of capital, technology and policies, and regard the development of the solar photovoltaic industry as one of their national energy security and sustainable development strategic goals.

[0003] In solar cell modules, the back sheet has always been the most important material other than silicon wafers. The current back sheet products are mainly divided into two types: fluorine-containing and fluorine-free back sheets. Fluorine materials in fluorine-containing backsheets are generally PVF (poly...
