Abstract:
An array of photovoltaic cells comprising:a semi-insulating substrate comprising a Group III-V composite;at least 90 independent photovoltaic cells containing doped single crystal semiconductor materials at least one of which has a direct bandgap of at least 1, said cells attached to a surface of said semi-insulating substrate, said doped semiconductors of a first independent photovoltaic cell having an n side of an n-p junction or p-n junction interconnected to a p side of an n-p junction or p-n junction of a second independent photovoltaic cell; andan optically opaque reflective coating covering said surface of said semi-insulating substrate between said independent photovoltaic cells, andwherein said reflective coating comprises a metal reflective layer interconnecting said n side and said p side in said independent photovoltaic cells and an insulator material.
