    摘要: A photovoltaic cell structure for manufacturing a photovoltaic device. The photovoltaic cell structure includes a substrate including a surface region. A first conductor layer overlies the surface region. The photovoltaic cell structure includes a lower cell structure. The lower cell structure includes a first P type absorber layer using a first semiconductor metal chalcogenide material and/or other semiconductor material overlying the first conductor layer. The first P type absorber material is characterized by a first bandgap ranging from about 0.5 eV to about 1.0 eV, a first optical absorption coefficient greater than about 104 cm−1. The lower cell structure includes a first N+ type window layer comprising at least a second metal chalcogenide material and/or other semiconductor material overlying the first P absorber layer. The photovoltaic cell structure includes an upper cell structure. The upper cell structure includes a second P type absorber layer using a third semiconductor metal chalcogenide material. The second P type absorber layer is characterized by a second bandgap ranging from about 1.0 eV to 2.2 eV and a second optical absorption coefficient greater than about 104 cm−1. A second N+ type window layer comprising a fourth metal chalcogenide material overlies the second P absorber layer. A tunneling junction layer is provided between the upper cell structure and the lower cell structure.

    摘要: A thin film material structure for solar cell devices. The thin film material structure includes a thickness of material comprises a plurality of single crystal structures. In a specific embodiment, each of the single crystal structure is configured in a column like shape. The column like shape has a dimension of about 0.01 micron to about 10 microns characterizes a first end and a second end. An optical absorption coefficient of greater than 104 cm−1 for light in a wavelength range comprising about 400 cm−1 to about 700 cm−1 characterizes the thickness of material.

    摘要: A tandem photovoltaic cell. The tandem photovoltaic cell includes a bifacial top cell and a bottom cell. The top bifacial cell includes a top first transparent conductive oxide material. A top window material underlies the top first transparent conductive oxide material. A first interface region is disposed between the top window material and the top first transparent conductive oxide material. The first interface region is substantially free from one or more entities from the top first transparent conductive oxide material diffused into the top window material. A top absorber material comprising a copper species, an indium species, and a sulfur species underlies the top window material. A top second transparent conductive oxide material underlies the top absorber material. A second interface region is disposed between the top second transparent conductive oxide material and the top absorber material. The bottom cell includes a bottom first transparent conductive oxide material. A bottom window material underlies the first bottom transparent conductive oxide material. A bottom absorber material underlies the bottom window material. A bottom electrode material underlies the bottom absorber material. The tandem photovoltaic cell further includes a coupling material free from a parasitic junction between the top cell and the bottom cell.
