Transmittance Map of Glass Plate Coated with TCO Film Measured

A solar cell is composed of various parts, including ptype and n-type semiconductors, anti-reflective film, TCO (transparent conductive oxide) film, and glass plate, etc.
Here, we report on the transmittance measurement of a glass plate coated with TCO film. TCO films are transparent as well as electrically conductive, and examination of the transmittance distribution is important for evaluating both the TCO film and glass substrate. Here we introduce the measurement of the transmittance distribution (map) in glass plate coated with TCO film using the SolidSpec-3700 UV-VIS-NIR spectrophotometer.


It is clear that variation on the order of several percent exists at both 600 nm and 1500 nm, depending on the points compared in this sample.
These results indicate that such automatic measurement using the automatic X-Y stage is effective for evaluation of transmittance distribution in glass plates and other solar cell materials.
