Transparent conductive oxide (TCO) coatings are a functional component of thin film photovoltaic (PV) modules. PV module manufacturers require cost effective, high quality TCO coatings, which will survive the PV manufacturing process and have a working life of over 20 years. TCO coatings are generally manufactured on glass using two different avenues: either directly on the glass production line by atmospheric pressure chemical vapor deposition (APCVD) or by an off line batch process such as CVD or sputter-deposition. With the PV industry continuously improving its competitive position, low cost materials and processes are now crucial. This paper compares the economics, performance and durability for both the on-line and off-line methods. It reviews results from the literature and testing of two types of TCO: on-line SnO2:F (FTO) and off-line ZnO:Al (AZO).
