Abstract: High-efficiency Inverted Metamorphic (IMM) multi-junction solar cells are being developed at Spectrolab for use in space and near-space applications. Recently, large-area (26-cm 2) IMM3J cells achieved a 1-sun, AM0 conversion efficiency of 32% with an open-circuit-voltage of 3.04 V, a short-circuit current-density of 16.7 mA/cm 2, and a fill factor of 0.84.
We are developing flexible and lightweight III-V multijunction solar cells for space applications fulfilling different power density requirements. High efficiency designs such as the 3J inverted metamorphic can achieve power densities of 3 kW/kg. Lower cost designs based on GaInP/Ga(In)As/Ge 3J lattice matched solar cells can achieve 1 kW/kg and are interesting for

Introduction Starting from the 1953 - year when the semiconductor solar cell (SC) was invented, - SCs were mainly applied in the space satellite energy systems. Up to 1990 the solar cells were created on the base of single crystal, poly-crystal and amorphous Si.
Using the energy bandgap of semiconductors as a design parameter is critically important for achieving the highest efficiency multijunction solar cells. The bandgaps of lattice-matched semiconductors that are most convenient to use are rarely those which would result in the highest theoretical efficiency. For both the space and terrestrial solar spectra, the efficiency of 3
