TCO coated Glass On-line hard coating for Solar and Refrigerator Door

TCO glass (Transparent Conducting Oxide) is a special type of glass with a thin film of transparent conductive oxide (such as indium, tin, or zinc oxide) deposited on its surface using physical or chemical methods. It possesses excellent light transmittance and conductivity, and is widely used in thin-film solar cells, flat panel displays, touchscreens, and LEDs.

Its core advantage is balancing the two contradictory properties of "high transparency" and "high conductivity". Without adding additional structures, it can simultaneously undertake the functions of light transmission and electrical conduction. It is a core supporting material for thin-film photovoltaic cells (such as cadmium telluride and perovskite cells) and BIPV glass, especially suitable for scenarios with dual requirements for appearance and performance, such as BIPV curtain walls and skylights. It is also an indispensable basic material in the optoelectronic and new energy fields.

Available Thicknesses of TCO Conductive Glass

The thickness of TCO conductive glass is mainly customized according to its application scenarios (especially the structural requirements of BIPV glass), load-bearing requirements and processing technology. The mainstream thickness ranges from 0.7mm to 8mm, among which the common thicknesses suitable for BIPV scenarios are concentrated in 3.2mm~4mm, which can be specifically divided into the following categories:

• Ultra-thin Type (0.7mm~2.2mm): It is mainly used for scientific research experiments, small photovoltaic modules or special BIPV scenarios with extreme requirements for weight and thickness (such as curved curtain walls and lightweight skylights). Common specifications are 0.7mm, 1.1mm, 1.6mm and 2.2mm. It has the characteristics of light weight and good flexibility, and can adapt to complex shapes, but its load-bearing and impact resistance are relatively weak, and it needs to be used with composite structures to improve stability.
• Regular Type (3.2mm~4mm): It is the most mainstream thickness specification, suitable for most BIPV scenarios (such as curtain walls, skylights and photovoltaic sunshade panels), and is also the core specification of current industrial mass production. Among them, 3.2mm and 4mm are the most commonly used, which are perfectly compatible with the lamination and insulation structures of BIPV glass. They can not only meet the load-bearing and impact resistance requirements of the building structure, but also ensure the balance between light transmittance and conductive performance. It is the standard thickness choice for the outer glass of BIPV in the cadmium telluride route, and some manufacturers can provide customized products within this thickness range.

• Thick Type (5mm~8mm): It is mainly used for BIPV scenarios with high requirements for structural strength (such as large public building curtain walls, outdoor photovoltaic canopies and buildings in high wind pressure areas). Common specifications are 5mm, 6mm and 8mm. The substrate is mostly thickened tempered glass, which has stronger impact resistance and wind pressure resistance, and can adapt to complex outdoor environments. It can be customized according to the design requirements of the building structure, but its weight is relatively large, so the building load-bearing design needs to be considered.
