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 photovoltaic material to form a second grid portion; curing the first conductive material, at a temperature sufficiently low to avoid significant deformation of the laminate sheet, prior to laminating the photovoltaic material and the laminate sheet together; drying the second conductive material prior to laminating the photovoltaic material and the laminate sheet together; after the steps of curing and drying, press-fitting the laminate sheet to the photovoltaic material prior to laminating the photovoltaic material and the laminate sheet together; and laminating the photovoltaic material and the laminate sheet together.
