Five-junction III-V solar cell with 35.1% efficiency

Scientists from the Chinese Academy of Sciences (CAS) have developed a high-performance five-junction (5J) solar cell using an inverted metamorphic (IMM) design. The cell incorporates subcells made of various materials with specific bandgap energies. The research team achieved a notable power conversion efficiency of 35.1% by addressing stress-related issues and employing advanced coating techniques.
