Photovoltaic conductive paste is the core functional material of the metal electrode of solar cells, and its performance directly affects the photoelectric conversion efficiency and reliability of the battery! However, the traditional preparation process often faces the following difficulties:
01 Difficulty in uniform dispersion
Nanosilver powder is easy to agglomerate, and requires three-roll rolling or ultrasonic assisted dispersion. The process parameters (shear force, temperature) have low tolerance, improper control of slurry viscosity will lead to sedimentation or uneven coating, and the traditional mixing equipment has poor mixing effect, etc. ~
02 High viscosity slurry is difficult to handle
The viscosity is as high as 5000cp or even 100,000cp. Ordinary agitators are prone to "swirl" phenomenon, making it difficult to achieve uniform dispersion, resulting in uneven particle size.
03 Batch stability is not easy to control
Manual operation or traditional equipment is difficult to accurately control parameters such as temperature and speed, and differences between batches may cause fluctuations in battery efficiency.
How to solve the pain points of the industry?
Kosmix high-efficiency homogenizing vacuum emulsifier gives you the answer!
Uniform distribution of particle size: Through high-speed shearing and homogenizing technology, metal powder agglomerates are instantly broken to make the particle size distribution uniform, while solving the problem of multi-phase material stratification.
Modular design: The equipment is integrated with a vacuum system, which can maintain the vacuum degree in the pot below -0.095MPa, and multiple sets of standard quick interfaces are reserved, which can flexibly adapt to the research and development needs of new materials such as silver-clad copper and low-temperature silver paste.
Ultra-high viscosity is easy to control: Even the "stubborn" slurry of 100,000 cp can achieve ultra-uniform mixing and dispersion, and improve the conductivity efficiency after coating the substrate.
Intelligent temperature and speed control, say goodbye to batch differences: KVM laboratory vacuum emulsifier adopts the sixth generation of emulsification technology, perfectly matched with intelligent software to accurately record experimental parameters, one-click reproduction process, to ensure the consistent performance of each batch of slurry.
In today's rapid development of the photovoltaic and semiconductor industries, the innovation of material preparation technology is the key to promoting industrial upgrading.
With the dual breakthroughs in software and hardware, the Kosmix series emulsifier mixer has effectively solved the difficulties in preparing conductive slurry, and also paved the way for the commercialization of next-generation technologies such as heterojunction batteries and BC batteries.
