About Establis

Earth receives enough sunlight in one hour to satisfy all human needs in a year. Using solar energy will reduce harmful CO2 emissions and resolve the forthcoming energy deficit. The market for stable, mass-produced Organic Solar Cells is estimated at one billion Euros by 2016.

More about Establis

Researchers social network

ESTABLIS will train a team of 11 PhDs and 4 Postdocs to become the scientific leaders in industry and academia. ESTABLIS Fellows will excel.

Research on organic solar cells

Complementarity is at the heart of Establis. To develop Organic Solar Cells requires a concerted combination of physical, synthetic and modelling capabilities. Establis members are working together–across preconceived scientific boundaries–to accelerate the production of Organic Solar Cells.

Partnerships & collaborations

Our Industrial Partners and Associate Partners ensure that the training and technology is economically feasible.

EU support

The EEC is constructively investing more than 3.9 M€ in Establis to train, research and collaborate at the highest international level and ensure our energy platform for the 21st century.

Paper for the 15th Conference of Doctoral Students ELITECH ’13:

Inverted geometry organic solar cells (IG OSC) were investigated in order to get more information about the process of degradation. The IG OSC devices were degraded by exposing in an ambient atmosphere and illuminated under the sunsimulator (AM1.5G) for different degradation times in the range of up to 2 hours. The AFM roughness values of PEDOT : PSS surfaces do not show any essential change during 2 hours of degradation. The TOF-SIMS depth profiles of the different characteristic fragment ions of the used organic materials also showed no essential change after 2 hours degradation. These features points out that the 2 hours degradation process does not lead to the real chemical changes of the investigated PEDOT : PSS layers.
