The compact cleaning module can be adapted to the respective web width and easily integrated into roll-to-roll production lines. (Photo credit: Research project team PV-CO2) The automated CO2 snow jet cleaning system reliably removes burrs in an industrial-compatible process. The cleaning effect is based on a combination of thermal, mechanical, solvent, and sublimation effects. (Image source: Research project team PV-CO2) The effects of deburring were demonstrated by measuring the IV curve of modules produced on substrates that were untreated (d), manually cleaned (e), and cleaned using the CO2 snow jet technology (f). b and c show the light and dark curves of the three differently-treated modules. In the DLIT images of the modules (d, e, f), the bright areas indicate hot, localized spots, which are particularly visible in the interconnection zones of the uncleaned modules.

It supports the upscaling of laboratory tests to small production series. (Photo credit: Sciprios GmbH)

quattroClean snow jet technology for cleaning electrodes after laser structuring

Automated cleaning process for printed photovoltaic modules manufactured using roll-to-roll technology

Roll-to-roll production lines enable printed photovoltaic modules to be produced particularly cost-effectively. To avoid short circuits, however, conductive burrs created when the front electrode is laser structured previously had to be removed manually in a way that was not compatible with the indu…
