Abstract: 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.

Abstract: 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.
