Solar photovoltaic (PV) devices, e.g., those based on the Copper Indium Selenide (CIS) family of absorbers, including CuIn(1-x)Ga(x)Se2 (CIGS) absorber thin-film PV devices, are provided. Embodiments provide PV devices comprising an alkali metal-containing polymeric film (ACPF), which is a film formed from a composite comprising an alkali metal-containing material and a polymer. Embodiments of this disclosure also provide PV devices comprising a thermally stable polymer film that does not contain an alkali metal (TSP). Included within the embodiments of this disclosure are flexible PV devices comprising a flexible base substrate onto which one or more ACPFs and / or TSPs is / are provided, as well as flexible PV devices wherein an ACPF or TSP itself constitutes the base substrate in the form of a stand alone film. Processes for making such flexible PV devices include roll-to-roll processes. PV devices disclosed herein will provide improved energy conversion efficiencies as a result of the delivery of sodium dopant into the absorber layer. Also disclosed are combinations of such PV devices and batteries that may store energy generated from the PV absorber. This disclosure also relates to shunt circuits for connecting the PV absorber to a battery in a combination PV / battery device and to array connectors for connecting such PV devices, either with or without batteries.

A fender for absorbing forces generated from an impact includes a depending attachment flange which comprises a vertically aligned section depending from an exterior portion of the fender and a horizontally aligned section depending from the vertically aligned section adapted for mounting to a vehicle wherein the vertically aligned section includes vertically aligned section including a plurality of reinforcing sections for increasing the stiffness of the vertically aligned section and a plurality of openings for reducing the stiffness of said vertically aligned section wherein each of said openings is positioned adjacent a respective reinforcing.

A system for installing carpet including a sheet which essentially includes a non-woven or flexible plastic backing with adhesive on both the top and bottom sides of the backing is disclosed. Release paper is placed on the adhesive on at least one side of the backing. When the carpet is ready to be installed the release paper from the side of the backing is removed so that the backing may be applied to a subfloor which may be a floor or pre-existing carpet. A carpet tile or carpet is placed on the top side of the backing. Thus, the present system provides dimensional stability to carpet tiles or carpet and to the existing floor.

A tyre for off-road motorcycles has a tread band provided with blocks, a carcass structure with crossed plies and at least one zero degree belt layer with limited angular extension, i.e., a zero degree belt layer which does not extend up to the axially outer edges of the tread band.

A non-pneumatic wheel having a thermoplastic wheel hub includes a center hub for attachment to a wheel bearing of a vehicle. The center hub has a central shaft aperture extending axially therethough and a plurality of lug apertures spaced radially from and circumferentially about the central shaft aperture. The thermoplastic wheel hub also includes a plurality of ribs extending radially outwardly from the center hub. The thermoplastic wheel hub further includes a cylindrical tire mount connected to the ribs and extending axially in substantially a cylinder for mounting a non-pneumatic tire thereon.

Provided is a method for improving the dimensional stability of wood and wood products. The method comprises impregnation of wood with fluorocompounds. In one embodiment, the method comprises the impregnation of wood or wood products with a composition comprising fluoro-polymer emulsions and / or dispersions.
