Abstract
Official abstract text for this publication.
Methods for improving the performance and lifetime of irradiated photovoltaic cells are disclosed, whereby Group-V elements, and preferably nitrogen, are used to dope semiconductor GaAs-based subcell alloys.
First claim
Opening claim text (preview).
We claim: 1. A method for repairing radiation-induced damage to photovoltaic cells comprising the steps of: providing a photovoltaic cell made by sequentially growing semiconductor alloys that are lattice-matched to a Ge substrate; providing at least one subcell layer comprising a GaAs-based material having a lattice and a first current and voltage retention; providing at least one subcell layer material comprising an amount of group-V element, said group-V element subcell lay…
