The OLEDSOLAR Collaborative Project

Marja Vilkman (VTT)

The OLEDSOLAR project is concerned with innovative manufacturing processes and in-line monitoring techniques for the OLED (Organic Light Emitting Diodes), thin film and organic photovoltaic industries (CIGS (Copper indium gallium selenide) and OPV (Organic Photovoltaic)). The project has been running for almost three years and is now in its final phase, in which the tools and processes developed will be implemented on pilot and production lines.

A multidisciplinary team of leading European RTOs and industries have collaborated their efforts in a joint 36 month effort to execute the related project activities.

The thin-film opto-electronic production technologies developed as part of this project will enable a wealth of new applications for solar cells, from installations on curved surfaces to building-integrated solar generation.

Organised as 8 closely interrelated and interacting work packages, this coordinated European action strives for maximum impact in R&D, product and business development as well as impact in our society.

 

Hyperspectral Imaging (HSI) for the quality control of organic electronics: Water vapour transmission rate (WVTR) and more

Wulf Grählert (Fraunhofer Institute for Material and Beam Technology IWS)

Hyperspectral imaging (HSI) allows spatial and spectral analysis of surfaces and layer systems and enables access to qualitative or quantitative sample properties. The presentation will show the potential of HSI for quality control in the field of organic electronics. In particular, the fast and non-destructive prediction of the water vapour transmission rate (WVTR) of barrier films by HSI in combination with machine learning will be-discussed. This inspection technology, developed within OLEDSOLAR, is ‘semi’ in-line capable and reduces the measurement time of WVTR from days/weeks to a few minutes.

 

Profile scanning using spectral reflectance on thin film application

Ioannis Kakogiannos (IRIS)

IRIS will present its development work on an optical gauge for non-contact thickness measurement of multilayer films. The system is based upon spectral reflectance and can be integrated in a scanning frame for in-line web measurements.

 

In-line thermography defect detection in solar panel production

Haitao Zheng (TWI)

TWI will deliver a presentation on its Dark Lock-in Thermography (DLIT) system for detecting defects in solar panels. The aim is to apply this new monitoring technique in the OLED and thin film photovoltaic industries (CIGS and OPV), to improve the quality and yield of the fabricated devices, as well as improving processing efficiency and sustainability.

 

Who should attend

Developers and users in the field of organic electronics, manufacturers of solar cells, thin films and modules and other continuous production processes, where 100% control of product quality is highly desirable.

 

This OLEDSOLAR project has received funding from the European Union's Horizon 2020 research and innovation programme under grant agreement No 820789.
