摘要

Ap+-Al0.36Ga0.64As+-In0.5Ga0.5P heterojunction tunnel diode with bandgap Eg=1.9 eV was fabricated. Doping levels of1×1020 cm-3 and 5×1019 cm-3 were achieved in the p and n side of the diode usingcarbon and selenium respectively, resulting in a peak current, Jp=80 A/cm2. This diode is used to interconnect the highand low band gap cells in a cascade solar cell structure. For a forwardcurrent of 20 A/cm2, the expected current density at 1000Suns operation, there is only a 20 mV drop across this tunnel junction
