    We present a fabrication method for high-efficiency GaInP/GaAs/GaInNAs triple junction solar cells, employing molecular beam epitaxy (MBE) and metal-organic chemical vapor deposition (MOCVD) processes. The method combines the advantages of both epitaxial techniques, the high quality of MBE-grown dilute nitrides and fast growth rate offered by MOCVD for standard III-V compounds. The GaInNAs bottom junction is first grown by MBE and then the rest of the structure is deposited by MOCVD. Triple-junction cells with conversion efficiency of ~29% at AM0 are demonstrated, opening a new perspective on cost-effective fabrication of high-efficiency multijunction solar cells for space and concentrated photovoltaic applications.
