    摘要: In an annealing process, a Kesterite film is provided on a substrate. The Kesterite film and the substrate are generally planar, have an interface, and have a substrate exterior side and a Kesterite exterior side. An additional step includes locating the cap adjacent the Kesterite exterior side. A further step includes applying sufficient heat to the Kesterite film and the substrate for a sufficient time to anneal the Kesterite film. The annealing is carried out with the cap adjacent the Kesterite exterior side. In another aspect, the film is not limited to Kesterite, and the cap is employed without any precursor layer thereon. Solar cell manufacturing techniques employing the annealing techniques are also disclosed.

    摘要: Electrical contact to the front side of a photovoltaic cell is provided by an array of conductive through-substrate vias, and optionally, an array of conductive blocks located on the front side of the photovoltaic cell. A dielectric liner provides electrical isolation of each conductive through-substrate via from the semiconductor material of the photovoltaic cell. A dielectric layer on the backside of the photovoltaic cell is patterned to cover a contiguous region including all of the conductive through-substrate vias, while exposing a portion of the backside of the photovoltaic cell. A conductive material layer is deposited on the back surface of the photovoltaic cell, and is patterned to form a first conductive wiring structure that electrically connects the conductive through-substrate vias and a second conductive wiring structure that provides electrical connection to the backside of the photovoltaic cell.
