(author)KF and NaF treatments were done for single-stage co-evaporated CuIn0.7Ga0.3Se2. The absorber layers were grown on a substrate with an alkali barrier layer and NaF was either added before or after absorber layer growth. No differences were found on the device performance amongst the procedures to add Na. This is expected if the single-stage...article 2019

Gaucher, E. (author), Schoenball, M. (author), Heidbach, O. (author), Zang, A. (author), Fokker, P.A. (author), van Wees, J.D. (author), Kohl, T. (author)In order to reach Europes 2020 and 2050 targets in terms of greenhouse gas emissions, geothermal resources will have to contribute substantially to meeting carbon-free energy needs. However, public opinion may prevent future large-scale application of deep geothermal power plants, because induced seismicity is often perceived as an unsolicited...article 2015

(author)The GEISER (Geothermal Engineering Integrating Mitigation of Induced SEismicity in Reservoirs) project is co-funded by the European Commission to address the mitigation and understanding of induced seismicity (IS) in geothermal engineering. The aim of the project is to contribute to the improvement of the concept of EGS by investigating the role...conference paper 2011
