OVERVIEW
——

Kovar alloy, also known as iron nickel cobalt alloy, is a special metal alloy widely used in fields such as electronics, aerospace, precision instruments, and medical equipment. Its unique physical and chemical properties make Kovar alloy play an indispensable role in situations where high-precision matching of thermal expansion coefficients is required.

We offer Kovar Alloy Foil for Space solar string, each specifically designed for missions to LEO, MEO, GEO or interplanetary applications.

Application

——

With the rapid development of space technology and complex space missions, the demand for space solar cells continues to grow. Space solar cells are facing more severe challenges than ever before: higher conversion efficiency and better radiation resistance. As the main power source for spacecraft, III-V multi junction solar cells have become the main focus of space applications today due to their high efficiency and strong radiation resistance. The key to obtaining high-quality crystals and improving cell efficiency in multi junction solar cell structures is to meet lattice matching and bandgap matching conditions. In recent years, new materials and structures for high-efficiency multi junction solar cell structures have emerged, which have the characteristics of low cost, lightweight, flexibility, and high power to quality ratio. In addition to efficiency and other characteristics, radiation resistance is another unique criterion for space solar cells. Therefore, in the past few decades, the radiation effects and radiation damage mechanisms of solar cells have been widely studied.
