Abstract

The present invention presents apparatus and methods for processing substrates (150) of a screen printing chamber (102) whereby repeatable and accurate screen printing patterns are delivered on one or more processed substrates. In one embodiment, the screen printing chamber is used to perform a screen printing process for a production line of partially crystalline silicon solar cells, wherein the substrate is patterned with a predetermined material. In one embodiment, the screen printing chamber is a processing chamber located within a rotary line tool or a Softline™ tool from Baccini S.p.A., Applied Materials, Inc., Santa Clara, CA.

Description

technical field [0001] The present invention relates to a system for depositing a patterned layer onto a substrate surface, such as a screen printing process. Background technique [0002] Solar cells are photovoltaic (PV) devices that convert sunlight directly into electrical energy. PV devices typically have one or more p-n junctions. Each joint includes two distinct regions within the semiconductor material, one side being a p-type region and the other side being an n-type region. After the p-n junction surface of the PV cell is exposed to sunlight (composed of photon energy), the sunlight is directly converted into electrical energy through the action of PV. PV solar cells generate a specified amount of electrical energy, and the cells are laid out in a module size to deliver a predetermined amount of system power. PV modules are combined into panels with special frames and connectors. Solar cells are typically formed on silicon substrates, which can be monocrystalli...
