Triple-junction solar cells
We are running GaInP/GaAs/Ge triple-junction cells fabricated by a MOCVD technique and made of high-quality III-V compounds materials that deliver significantly high efficiency.Compared with conventional solar cells, multi-junction solar cells are more efficient but also more expensive to manufacture. Triple-junction cells are [...]
