PP/PE Photovoltaic cell backsheet is an important part of the PV module, located on the back of the PV cell. Its role is to play a protective effect on the PV cell, preventing the cell from external environmental factors such as moisture, oxygen, ultraviolet radiation, etc. erosion, thereby extending the service life of the PV module.
Performance Characteristics
Weather resistance:
PP/PE photovoltaic cell backsheets have excellent weather resistance and can maintain stable performance under long-term UV irradiation, high temperature, severe cold, humidity, sand and other environments.
Barrier performance:
PP/PE photovoltaic cell backsheets can effectively block the penetration of water vapor and oxygen, and their barrier performance can be realized through special material formulations and multi-layer composite structures.
PP/PE photovoltaic cell backsheets are mainly used in the field of solar photovoltaic power generation. Whether it is large-scale terrestrial photovoltaic power stations, such as those constructed in vast deserts, grasslands, etc., or distributed photovoltaic power generation systems, such as those installed on the roofs of industrial plants and residential houses, PP/PE photovoltaic cell backsheets play a key role in protecting the solar module and ensuring that it is able to operate efficiently and stably for a long period of time, Stable, long-term operation of PV modules.
