Abstract
A photovoltaic structure includes: a hole-selective contact comprising an anodized aluminum layer overlaying a different electrode metal and a plurality of contact vias that extend through the anodized aluminum layer to the different electrode metal, wherein locations of the plurality of contact vias define an ordered array; an absorber comprising a chalcopyrite (Ag,Cu)(Ga, In)S,Se:Alk, where Alk represents at least one alkali element, the absorber comprising at least a residual of a contiguous nucleation template over the anodized aluminum layer; an electron-selective contact; and a plurality of nanorods located in the plurality of contact vias, the plurality of nanorods providing ohmic contacts between the hole-selective contact and the different electrode metal at their interface at a bottom of each contact via, and comprising at least a residual of at least one surfactant and at least a residual of at least one minority alloy constituent.
