Gallium arsenide-based solar cells are typically favored over crystalline silicon in industry because they have a higher efficiency and degrade more slowly than silicon in the radiation present in space. The most efficient solar cells currently in production are multi-junction photovoltaic cells. CETC Solar Energy's multi-junction solar cells have contributed to thousands of satellites for over 10 countries in 30 years. CETC Solar Energy's latest generation solar cells and Coverglass Interconnected Cell (CIC) assemblies are the highest efficiency commercially available products in the industry.
A combination of several layers of gallium arsenide, indium gallium phosphide, and germanium is used to capture more energy from the solar spectrum. The CIC assemblies manufactured at CETC Solar Energy employ the most advanced interconnect welding techniques in the industry that offer the highest reliability under severe space radiation environment and thermal stress conditions. The latest weld process capability methodologies and statistical process control are in practice at CETC Solar Energy to ensure the most consistent and reliable assembly interconnections
