One embodiment includes a photoabsorbing surface and a plurality of three-dimensional contacts formed on the photoabsorbing surface. The plurality of three-dimensional contacts are spaced apart so that radiation is incident on a portion of the photoabsorbing surface. In addition, the three-dimensional contacts include at least one surface that redirects radiation incident on the three-dimensional contacts onto the photoabsorbing surface. Processes for manufacturing solar cells in accordance with many embodiments of the invention include: fabricating prototype three-dimensional contacts; forming a master structure for use in a gravure printing process using the prototype three-dimensional contacts; and forming three-dimensional contacts using a printing material formed on a substrate material using the master structure in a gravure printing process.

    Abstract: The principles of the present invention are used to reduce the conduction band offset between chalcogenide emitter and pnictide absorber films. Alternatively stated, the present invention provides strategies to more closely match the electron affinity characteristics between the absorber and emitter components. The resultant photovoltaic devices have the potential to have higher efficiency and higher open circuit voltage. The resistance of the resultant junctions would be lower with reduced current leakage. In illustrative modes of practice, the present invention incorporates one or more tuning agents into the emitter layer in order to adjust the electron affinity characteristics, thereby reducing the conduction band offset between the emitter and the absorber. In the case of an n-type emitter such as ZnS or a tertiary compound such as zinc sulfide selenide (optionally doped with Al) or the like, an exemplary tuning agent is Mg when the absorber is a p-type pnictide material such as zinc phosphide or an alloy of zinc phosphide incorporating at least one additional metal in addition to Zn and optionally at least one non-metal in addition to phosphorus. Consequently, photovolotaic devices incorporating such films would demonstrate improved electronic performance.

    Abstract: The present invention uses a treatment that involves an etching treatment that forms a pnictogen-rich region on the surface of a pnictide semiconductor film The region is very thin in many modes of practice, often being on the order of only 2 to 3 nm thick in many embodiments. Previous investigators have left the region in place without appreciating the fact of its presence and/or that its presence, if known, can compromise electronic performance of resultant devices. The present invention appreciates that the formation and removal of the region advantageously renders the pnictide film surface highly smooth with reduced electronic defects. The surface is well-prepared for further device fabrication.
