Automated flexible solar cell fabrication and interconnection utilizing rolls expanded metallic mesh

摘要

A method for forming photovoltaic cells comprises providing a first roll of a photovoltaic material and a second roll of an expanded metallic mesh. The photovoltaic material comprises a photoactive material adjacent to a flexible substrate, and the expanded metallic mesh comprises a plurality of openings. Next, an electrically insulating material is provided adjacent to an edge portion of the photovoltaic material. The photovoltaic material from the first roll can then be brought in proximity to the expanded mesh from the second roll to form a nascent photovoltaic cell. The electrically insulating material can be disposed between the expanded metallic mesh and the photovoltaic material. Next, the nascent photovoltaic cell is cut into individual sections to form a plurality of photovoltaic cells.

1. A method for forming photovoltaic cells, comprising:
(a) providing a first roll of a photovoltaic material and a second roll of an expanded metallic mesh, wherein the photovoltaic material comprises a photoactive material adjacent to a flexible substrate, and wherein the expanded metallic mesh comprises a plurality of openings; (b) providing an electrically insulating material adjacent to an edge portion of the photovoltaic material; (c) directing the photovoltaic material from the first roll and the expanded metallic mesh from the second roll into a vacuum drum and pressing the photovoltaic material against the expanded metallic mesh to form a nascent photovoltaic cell, wherein the electrically insulating material is disposed between the expanded metallic mesh and the photovoltaic material; and (d) cutting the nascent photovoltaic cell into individual sections to form a plurality of photovoltaic cells.
