    Abstract: A photovoltaic device includes an electron blocking layer (EBL) and an absorber layer. The EBL is positioned between the absorber layer and a back contact layer. A material of the EBL is a cadmium zinc telluride Cd (1-y) Zn (y) Te, and a material of the absorber layer is a cadmium telluride selenide CdTe (1-x) Se (x) producing a lattice mismatch between the materials of the EBL and between the materials of the absorber of less than about two tenths of a percent when x ~ y and has a value less than about 0.4.

    Abstract: A photovoltaic device includes a substrate, a semiconductor stack and a transparent tunnel junction. The semiconductor stack includes an n-type layer selected from a first transparent conductive oxide layer, or a window layer, or both; and a p-type absorber layer disposed on the n-type layer, wherein the absorber layer consists essentially of CdSexTe(1-x), wherein x is from 1 to about 40 at. %. The transparent tunnel junction comprises a transparent interface layer of Cd y Zn (1-y) Te doped to be p+type, and a transparent contact layer doped to be n+type, and the interface layer is disposed between the p-type absorber layer and the transparent contact layer. In bifacial embodiments, the tunnel junction forms a transparent back contact and electrode; and in multi-junction embodiments, the tunnel junction forms a diode-like connector between top and bottom cells. The transparent contact layer may comprise tin oxide or zinc oxide doped with aluminum, fluorine or indium. The photovoltaic device may also include an electron reflector layer and/or an optical reflector layer.

    Abstract: A bearing inner race for a solar panel tracker positioning system includes a semi-circular shaped body having a first upper land and an oppositely facing second upper land. A first elongated aperture is positioned proximate to the first upper land and a second elongated aperture is positioned proximate to the second upper land. A first alignment ring is centered within the first elongated through aperture and a second alignment ring is centered within the second elongated through aperture. The bearing inner race also includes a ground stud integrally connected to the body in an as-cast condition of the body.
