We have completed the production of an automated inspection system to automatically analyse thin film photovoltaic modules. The system integrates an optical head, which delivers light onto the module, gathers its optical response, and guides the light into different spectroscopic modules for analysis. By means of advanced data processing techniques, this spectral information can be used to assess the quality and efficiency of thin film materials, during the manufacturing process. The early detection of manufacturing defects is of paramount importance to (1) identify manufacturing errors and implement early actions; (2) maximise production yield; (3) ensure the quality and reliability of the modules; and (4) minimise manufacturing waste.
The sensing probe has been attached to automatically XY scanning system, which allows automatically inspecting the properties of the modules across its surface.
