Photovoltaic silicon wafers are the core material of solar cells, and their production process requires the use of various chemicals and adhesives such as glue. The traditional curing method requires the use of ultraviolet lamps, which are not only bulky but also energy-intensive. In recent years, with the development of UVLED technology, more and more photovoltaic silicon wafer manufacturers have begun to adopt UVLED light curing technology, which has the advantages of low energy consumption, high efficiency, safety and environmental protection.
NO.1 Basic principles of UVLED light curing technology
UVLED light curing is a technology that uses ultraviolet rays emitted by UVLED to cure adhesives. When ultraviolet rays are irradiated to the surface of the adhesive, the monomers and low molecular weight substances in the adhesive will undergo a cross-linking reaction to form high molecular weight polymers, making the adhesive strong and durable. UVLED light curing technology has the following characteristics:
01High efficiency
UVLED has high light efficiency and can complete the light curing process in a short time, thus improving production efficiency.
02Low energy consumption
UVLED light sources can efficiently convert electrical energy into light energy and consume less energy than traditional ultraviolet lamps .
03Safety and environmental protection
is harmless to the environment and operators .
NO.2 Application of UVLED light curing in photovoltaic silicon wafer production
01 Backplane curing
The backplane is an important component of photovoltaic cells. Its main function is to protect the battery components and provide support. During the production process, the backplane needs to be bonded to the battery cell and cured to make it tightly bonded. The traditional curing method requires the use of lamps, while UVLED light curing technology can achieve efficient, safe and stable curing effects.
02 Silicon wafer bonding
In the production process of photovoltaic silicon wafers, multiple silicon wafers need to be bonded together to increase the output power of the battery module. UVLED light curing technology can achieve a more uniform and efficient curing effect, thereby improving the quality and efficiency of the battery module.
03 Transfer film
In the manufacturing process of photovoltaic silicon wafers, transfer films are also needed to make battery chips. Traditional curing methods require the use of ultraviolet lamps, while UVLED light curing technology can achieve more efficient and safe curing effects, thereby improving the manufacturing efficiency and quality of battery components.
