摘要:
Embodiments of the present invention are directed to a process for making solar cells. Particularly, embodiments of the invention provide simultaneously co-firing (e.g., thermally processing) metal layers disposed both on a first and a second surface of a solar cell substrate to complete the metallization process in one step. By doing so, both the metal layers formed on the first and the second surfaces of the solar cell substrate are co-fired (e.g., simultaneously thermally processed), thereby eliminating manufacturing complexity, cycle time and cost to produce the solar cell device. Embodiments of the invention may also provide a method and solar cell structure that requires a reduced amount of a metallization paste on a rear surface of the substrate to form a rear surface contact structure and, thus, reduce the cost of the formed solar cell device.

A common rail single fluid injection system including fuel injectors with the ability to produce multiple injection rate shapes. This is accomplished by including auxiliary filling orifices which selectively provide pressurized fluid to the check needle control chamber during injection events. In so doing, the speed and movement of the check needle is manipulated and differing injection rates may be achieved.

Embodiments of the present invention are directed to a process for making solar cells. In one embodiment, a method of manufacturing a solar cell device, includes providing a substrate having a first surface and a second surface, selectively disposing a first metal paste in a first pattern on the first surface of the substrate, forming a first dielectric layer over the first metal paste on the first surface of the substrate, forming a second metal paste in a second pattern over the first dielectric layer align with the first metal paste, and simultaneously heating the first and the second metal pastes disposed on the first surface of the substrate to form a first group of contacts on the first surface of the substrate, wherein at least a portion of the second metal paste forms the first group of contacts that each extend through the first dielectric layer to connect with the first metal paste to the first surface of the substrate.

A high voltage bushing assembly includes an insulator shell adapted to enclose an electrical conductor. An annular flange is slidably received over the insulator shell, the annular sleeve formed with a radially outwardly directed flange at an upper end and a radially inwardly directed flange at a lower end, with a sleeve portion extending axially therebetween. The insulator shell has an outside diameter and the sleeve portion has an inside diameter sized to create an annular, radial gap therebetween filled with a high thermal endurance fiberglass-reinforced epoxy resin.

Systems, devices, and techniques are disclosed relating to dispersion devices that include a slot waveguide coupled with another waveguide such as a strip waveguide. For example, one or more structural parameters can be obtained for a dispersion device, including a slot waveguide coupled to a strip waveguide, to cause the dispersion device to produce dispersion, having a dispersion profile, for an electromagnetic wave propagated through the dispersion device, the one or more structural parameters including one or more of a slot thickness for a slot of the slot waveguide or a spacing thickness between the slot waveguide and the other waveguide; and making the dispersion device, including the slot waveguide and the other waveguide, according to the structural parameters.

Clamshells for packaging produce, or other unit packaging, are labeled with unique codes. Harvest crates for transporting filled clamshells from the harvest, or other containers for transporting unit packaging, are also labeled with unique codes. A plurality of labeled un-filled clamshells are nested together and placed into each harvest crate before the harvest, and the codes from the clamshells and the harvest crate are stored in association. In some instances, clamshells are de-nested, labeled with pre-printed labels, and nested again before being placed into the harvest crates. At the harvest the clamshells are removed from the harvest crate, de-nested, filled with produce, packed back into the harvest crate, and moved into the distribution chain. The unique codes are further associated with other information such as harvest data.

Embodiments of the present invention generally provide apparatus and methods for altering the contour of a gas distribution plate within a process chamber without breaking vacuum conditions within the chamber. In one embodiment, a central support device adjusted to vary the height of a central region of a gas distribution plate with respect to the periphery of the gas distribution plate. In another embodiment, a plurality of central support devices is adjusted to vary the height of a central region of a gas distribution plate with respect to the periphery of the plate. In yet another embodiment, a plurality of central support devices and a plurality of mid-range support devices are adjusted to vary the height of certain regions of the gas distribution plate with respect to other regions of the gas distribution plate. In one embodiment, the contour of the gas distribution plate is altered based on changes detected within the process chamber.
