Photovoltaic module cleaner

摘要

The present invention relates to methods for cleaning semiconductors used in photovoltaic cells and modules, and methods for manufacturing p-n junctions for photovoltaic cells and modules. More particularly, the method comprises providing at least one semiconductor layer of a photovoltaic module and scrubbing the surface of the least one semiconductor layer in the presence of a chemical solution.

主权项

1. A method for preparing a semiconductor for a photovoltaic module, comprising:
providing a semiconductor layer over a photovoltaic module substrate; applying a chemical solution to a surface of the semiconductor layer; scrubbing the surface of the semiconductor layer with a scrubber in the presence of the chemical solution; and providing a back contact adjacent to the scrubbed surface of the semiconductor layer.
