Developing AMCoT in Solar Industry by Utilizing Industry 4 1 Technologies

Abstract

A massive uptake of renewable energy can hopefully replace fossil fuels and solve global warming problem However the cost of renewable energy is not comparable with traditional energy The product quality and production efficiency need to be optimized in order to reduce the manufacturing cost In solar cell manufacturing the transformation efficiency of solar cell is a critical factor for price competition and it is also the top priority of cost improvement To fulfill the requirements stated above the author proposes an advanced manufacturing cloud of things (AMCoT) by utilizing industry 4 1 technologies The automatic virtual metrology (AVM) system provides total inspection to achieve the goal of zero defects production; then tube-to-tube (T2T) control with reliance index (RI) and global similarity index (GSI) help to improve the process capability; finally factory-wide intelligent predictive maintenance (IPM) system increases the tool availability Anti-Reflection Coating (ARC) the most critical process of solar cell manufacturing will be used as illustrative example
