Abstract

Experimental study of the band structure at the heterojunction interfaces of GalnP solar cells was performed by admittance spectroscopy. Admittance measurements were analyzed using numerical simulations. A good agreement between simulation and experiment was obtained. A potential barrier of about 0.6 eV at the p-GaAs/p-AlInP interface formed due to the high valence band offset was observed by the experiment. This high barrier creates fundamental limitation for the usage of this interface in p-n GaInP solar cells. A way to reduce the effective barrier height to 0.25 ± 0.02 eV using a double layer p-AlGaAs/p-AlGaInP window avoiding deterioration of I-V curves was demonstrated.

<fC01 i1="01" l="ENG"><s0>Experimental study of the band structure at the heterojunction interfaces of GalnP solar cells was performed by admittance spectroscopy. Admittance measurements were analyzed using numerical simulations. A good agreement between simulation and experiment was obtained. A potential barrier of about 0.6 eV at the p-GaAs/p-AlInP interface formed due to the high valence band offset was observed by the experiment. This high barrier creates fundamental limitation for the usage of this interface in p-n GaInP solar cells. A way to reduce the effective barrier height to 0.25 ± 0.02 eV using a double layer p-AlGaAs/p-AlGaInP window avoiding deterioration of I-V curves was demonstrated.</s0>
