Abstract

Tunnel junctions are key for developing multijunction solar cells (MJSC) for ultra-high concentration applications. We have developed a highly conductive, high bandgap p⁺⁺-AlGaAs/n⁺⁺-GaInP tunnel junction with a peak tunneling current density for as-grown and thermal annealed devices of 996 A/cm² and 235 A/cm², respectively. The J-V characteristics of the tunnel junction after thermal annealing, together with its behavior at MJSCs typical operation temperatures, indicate that this tunnel junction is a suitable candidate for ultra-high concentrator MJSC designs. The benefits of the optical transparency are also assessed for a lattice-matched GaInP/GaInAs/Ge triple junction solar cell, yielding a current density increase in the middle cell of 0.506 mA/cm² with respect to previous designs.
