DESCRIPTION:Dr. Jens Ohlmann\, Fraunhofer-Institut für Solare Energiesyst
 eme ISE\nAbstract: Multi-junction solar cells dominate the efficiency tabl
 es of solar cells for a long time. The III-V semiconductors with their bro
 ad range of available bandgaps\, high absorption coefficients and high mat
 erial quality are ideal candidates for these devices. Today\, their applic
 ations range from space solar cells over concentrating photovoltaics to so
 lar-to-hydrogen production. This talk will cover the basics of III-V multi
 -junctions from the concept to production. Their various applications will
  be presented with a focus on the solar-to-hydrogen-production.\n\nBiograp
 hy: Jens Ohlmann is the head of the team III-V epitaxy processes at the Fr
 aunhofer ISE in Freiburg with a research focus on the epitaxy and characte
 rization of III-V semiconductors for multi-junction solar cell application
 s. He graduated at the University of Auckland (New Zealand) with a post-gr
 aduated Diploma in Science. Thereafter\, he finished his Diploma and PhD i
 n Physics at the Philipps-University-Marburg (Germany) on the epitaxy and 
 characterization of III-V tandem solar cells on Si-substrates.
