Solar cell efficiencies of tandem devices using these materials reached 34.6%[1], making this the fastest-advancing solar technology to date. From its side, CEA achieved 30.8%[2] efficiency with relatively large device (9 cm2). Nevertheless, stability challenges appear as the most important bottlenecks regarding the emergence of this technology on the market.

The LCT lab is leading the TACOS project which involves CEA/LITEN/LCT and LVME laboratories and is dedicated to the improvement of the intrinsic stability issues. In order to inhibit the defects and the related degradation mechanisms, numerous passivation approaches are used. Among them, the use of Metal Organic Frameworks (MOFs) is little explored and promises specific advantages due to their unique properties.

The aim of TACOS is to integrate MOFs from LVME and other sources into the LCT's Si/PVK tandems, to study materials (XRD, SEM, Photoluminescence, etc…) and to make aging studies of full devices following last recommended standards ISOS-L2 (light plus temperature) and ISOS-LC (light cycling).
