It is understood that in 2022, China's rapid development of the PV application market, January-October photovoltaic new installed capacity of 58.24 million kilowatts, a year-on-year increase of 98.7%, has exceeded the level of 54.88 million kilowatts for the whole year of 2021. 2022 the first three quarters of the new photovoltaic installed capacity, centralized, household, industrial and commercial three worlds.
Driven by national policy support and industry technology level improvement, China has gradually developed into one of the world's most important solar photovoltaic application markets, and is in an absolutely dominant position in the world's solar panel supply chain, with more than 75% of all key links in the solar photovoltaic industry. Among them, polysilicon accounts for 79.4%, silicon wafers for 96.8%, batteries for 85.1%, and modules for 74.7%.
A set of solar photovoltaic module is roughly composed of tempered glass, EVA film, cell, backsheet, aluminum alloy frame, junction box, module adhesive and other parts. Adhesive as one of the important auxiliary materials in the photovoltaic industry, the sustained and healthy development of the photovoltaic industry to the adhesive industry to bring a broader market space.
As solar photovoltaic modules are mainly used outdoors, encountered such as high temperature and high humidity, high and low temperatures, strong ultraviolet rays, ozone, wind and rain, and other natural conditions, so we need to use the photovoltaic adhesive on the photovoltaic panels around the outer frame, the junction box interface position to protect and prolong the service life of the photovoltaic module.
Photovoltaic adhesives in the application of photovoltaic components can be roughly divided into bonding, sealing, potting 3 categories, summarized as follows:
(1) Bonding and sealing of laminated components and aluminum alloy frame;
(2) Bonding of junction box and backplane;
(3) Potting of junction box.
Photovoltaic components have relatively high requirements for adhesives, which should have the characteristics of waterproof sealing, UV resistance, weather aging resistance, acid and alkali resistance. For the framework, backplane, junction box bonding sealing adhesive need to investigate the main speed of curing as well as moisture and heat aging after the bonding, mechanical properties and electrical properties; for the junction box potting adhesive need to investigate the main period of time as well as moisture and heat aging before and after the bonding, heat dissipation and electrical properties.
Jiadi new material organic silicone adhesive because of its excellent high and low temperature resistance, excellent adhesion, excellent aging resistance, excellent insulating properties, good elasticity, hydrophobicity, as well as the application of a simple process, production efficiency and other characteristics of the production of solar photovoltaic module encapsulation has been very well used in the production.
