VTT Finland: EL/PL/DLIT Characterization of various PV materials with LumiSolarCell


At VTT Technical Research Centre of Finland Ltd., one of their visions is to develop novel energy harvesting solutions with the help of flexible, lightweight organic or perovskite photovoltaics (PV). Then integrate these PV materials with other components, such as energy storage systems, sensors with Bluetooth, or near-field communication features.

The easy processing of these materials enables the design of your choice and several coating methods, using less energy than the production of conventional silicon solar cells. VTT offers material testing in the laboratory up to preparation of pilot-scale printed/coated photovoltaic devices and systems (including encapsulation) in a roll-to-roll fashion. They have several characterization methods to test solar cells, e.g. I-V curve testing in air or nitrogen, accelerated ageing, and optical quality control.
With the newly acquired LumiSolarCell system from greateyes, VTT is able to offer its partners multiple optical characterization solutions for the quality control of solar cells and modules. This is not only useful for roll-to-roll printed PVs but it can also be used with other PV technologies and various printed components. The LumiSolarCell system at VTT Oulu offers photoluminescence (PL), electroluminescence (EL), infrared (IR) imaging, and dark lock-in thermography (DLIT). For example, with printed free-form OPVs these tools provide valuable insight into the quality of the printed layers through non-destructive imaging techniques. The greateyes software platform provides a user-friendly approach for multiple modes of data acquisition.

About VTT Printed Intelligence:

VTT Printed Intelligence, a research division at VTT Technical Research Centre of Finland Ltd., makes it possible to create products that have never been seen before. For example, with the use of flexible, lightweight organic solar cells, illuminating surfaces, sensors integrated directly on skin and communicating labels for packaging. VTT Printed Intelligence offers roll-to-roll printed and hybrid manufacturing technology solutions for flexible electronics through its pilot factory with 20 years of experience and over 100 experts.
VTT Printed Intelligence offers unique in-house competence from material formulation and process development of pilot-scale roll-to-roll production to multi-technological knowledge of applications and systems. They also have a world-class, award-winning roll-to-roll (R2R) capable pilot factory (under one roof in Oulu, Finland) for R2R printing, R2R component assembly, R2R post processing, and R2R quality control. One of the many roll-to-roll fabricated components are solar cells.
