Abstract: A method including singulating a solar cell to form a plurality of strips, the singulation exposes unpassivated portions of the solar cell. The method further includes sorting the strips to ensure that similar shaped strips are grouped together, and re-passivating the plurality of strips, wherein the re-passivation eliminates active recombination centers. The method further includes aligning the re-passivated strips in an overlapping pattern, depositing electrically conductive adhesive (ECA) between the overlapped portions of the re-passivated strips, wherein the ECA adheres adjacent re-passivated strips to one another and electrically connects the re-passivated strips to form a string, electrically connecting a plurality of strings in parallel to form a string set, electrically connecting at least two string sets in series, and encapsulating the electrically connected string sets.

Abstract: The present invention discloses a method for preparing a simultaneous nitrogen and phosphorus removal lightweight material and the use thereof, and belongs to the technical field of environmental functional materials and sewage treatment. In the present invention, sulfur and an iron-based component are thoroughly melted and dispersed to obtain a molten mixture, where the iron-based component is a mixture of iron sulfides with carbonates of calcium and magnesium; and the above molten mixture is subjected to a foaming treatment to form the simultaneous nitrogen and phosphorus removal lightweight material. The simultaneous nitrogen and phosphorus removal lightweight material of the present invention has characteristics of high porosity, a large specific surface area, a light weight, and a high reaction activity.
