BEC is a consulting and engineering company in the field of Photovoltaics with a focus on troubleshooting PV-modules and PV power plants. 

This card was created to inform about hidden flaws inside of photovoltaic modules. These flaws are invisible to the human eye and need electroluminescence imaging technique to be detected. 

It took some weeks to find a printer who was courageous enough to print on so called 'spy mirror film'. When holding the the foil against a source of light, it reveals a compilation of electroluminescence images of broken cells. This then can be used to indicate a range of various damages which can be hidden underneath a module's flawless surface.
