Two-part screen printing for solar collection grid

摘要

Methods and apparatus relating to providing a collection grid suitable for use in PV modules. The disclosed collection grid may be at least partially applied to a protective laminate sheet in a manner that removes the high temperature requirements of conventional screen printed collection grids, to avoid unwanted heat-related deformation of the laminate sheet.

主权项

1. A method of providing a conductive collection grid to a photovoltaic cell, comprising:
applying a first conductive material to a substantially transparent, non-photovoltaic laminate sheet to form a first grid portion; applying a second conductive material to a light gathering surface of a photovoltaic material to form a second grid portion; after applying the second conductive material to the photovoltaic material, drying the second conductive material; and after drying the second conductive material, laminating the laminate sheet to the light gathering surface of the photovoltaic material.
