摘要：

We have identified the IMM structure as the best vehicle to achieve increased AM0 solar cell efficiency beyond the conventional 3-junction lattice matched GaInP/GaAs/Ge architecture. Building on our efforts to develop a 3J-IMM III-V based cell presented at the 33(rd) PVSC [1], we have developed a 4J-IMM AM0 solar cell. The top three sub-cells are identical to that incorporated in our 3J-IMM cell. The fourth sub-cell is composed of 0.70eV GaInAs. This cell structure required an extension of the transparent metamorphic ( MM) buffer layer to accommodate an additional 2% mismatch, a metamorphic tunnel diode, and the fourth ( MM) sub-cell.. The processing steps to fabricate this cell are very similar to those previously discussed with regard to the 3J-IMM cell. At 28 degrees C, our best CICed ( cover-glass interconnected cell) 4J-IMM 2x2 cm(2) cell achieved a 33.9% AM0 ( 135.3 mW/cm(2)) efficiency.
