Christophe Ballif (head of Photovoltaics and thin film electronics laboratory at EPFL-IMT, and director of CSEM PV-Center in Neuchâtel, Switzerland.)

In the thin film silicon solar cell technology, remarkable improvements and novel device design should allow for low production costs of solar modules with efficiency 10-11% in the range of 0.35-0.4€/Wp. The advantage of low cost and abundant materials has to be leveraged by clever solar park designs to compete with technologies with higher efficiency. Challenges to reach efficiencies of devices over 16% will be discussed.

Pavel Novák

Calculation of the crystal field parameters (CFP) of the rare-earth (RE) ions in solids is a formidable problem and until recently no robust ab-initio method to calculate them was available. The main problem is that in most approaches the 4f electrons of RE are allowed to interact with the nonspherical electron density they create themselves and this false selfinteraction completely distorts the crystal field. The second problem is that no ab-initio method is capable to determine correctly hybridization of the 4f levels with ligand electron states.

Cedric Rocha Leao (Federal University of ABC, Santo André, Brazil)

Functioning in a similar way to photovoltaics, semiconductors have been shown to work effectively as radiation detectors, capable of accuracy that allows even the identification of the isotope source of the radiation. The materials most suitable for that purpose, however, require high costs of fabrication or operation, severely limiting their large scale application for ends that go from medical to national security.
