Hybrid material bonding using AuSn solder for solar cells.
Hybrid material bonding technology to improve the durability and performance of solar cells.
In the solar cell industry, long-term reliability and high performance are required. Particularly for solar cells exposed to outdoor environments, it is important to prevent material degradation and maintain stable power generation performance. Poor bonding between dissimilar materials can shorten product lifespan. Our AuSn solder joint technology applies the sealing technology used in Citizen Watch's quartz devices to bond dissimilar materials with high precision and strength. 【Application Scenarios】 - Manufacturing of solar cell modules - Bonding of solar cell components using dissimilar materials - Solar cells used in harsh environments 【Benefits of Implementation】 - Improved long-term reliability due to high chemical and water resistance - Stable sealing performance under high vacuum conditions - Extended product lifespan
basic information
【Features】 - Strong chemical and water resistance (e.g., sodium hypochlorite) - Capable of handling low to high vacuum ranges - Possible to join dissimilar materials (glass, metal, ceramics, silicon) 【Our Strengths】 Citizen Fine Devices leverages the technology cultivated over many years in the field of functional components that require compact precision, high accuracy, and high resolution to provide high-value-added microdevice products. Based on the metal processing technology developed in watch manufacturing, we have developed a consistent production line from process design to processing, assembly, and functional testing, along with our own processing machines. We also possess mass production technology for brittle materials.

The area where Citizen Fine Devices demonstrates its strength is in the realm of functional components that require small size, precision, high accuracy, and high detail. We believe that our mission is to continue providing high-value-added microdevice products by leveraging the unique technologies we have developed over many years. Utilizing metal processing technology rooted in watch manufacturing, we have consistently supplied small, high-precision components to our customers for many years through a fully integrated production line that encompasses process design, machining, assembly, and functional testing, along with the unique development of our own processing machines. Additionally, mass-producing components with high precision and efficiency using brittle materials is also one of our core technologies. By integrating material technology with ultra-precision machining, thin-film technology, and bonding technology, we produce not only high-precision components such as ceramics and quartz but also high-quality functional device products like liquid crystal devices and sensing devices. Continuing to provide high-value-added products to the market is a significant dream for our employees. We will contribute to the creation of new value through manufacturing driven by the challenge spirit of each individual, working towards the realization of that dream.
