DESCRIPTION:Abstract: The remarkable advances over the past few years in p
 erformance of photovoltaic cells\, including the advent of new absorber ma
 terials\, allow us to take stock of how well we understand PV and if we ca
 n at all predict future progress. Apart from Si and InP\, for all cell typ
 es the “best efficiencies” improved\, while crystalline Si modules sho
 wed major cost reduction.  New cell types\, such as "sustainable CIGS-like
 "\, “perovskite” and quantum dot ones\, appeared on the scene. Develop
 ments tested and nearly reached the Shockley-Queisser limit.  The order --
 > increased efficiency criterion gained credibility from results on organi
 c and esp. perovskite cells. On top of this we seem to be finding new (or 
 re-new-ed) science!\n\nDavid Cahen studied chemistry & physics at the Hebr
 ew Univ. of Jerusalem (HUJ)\, Materials Research and Phys. Chem. at Northw
 estern Univ\, and biophysics of photosynthesis (postdoc) at HUJ and the We
 izmann Institute of Science\, WIS. After joining the WIS faculty he focuss
 ed on alternative sustainable energy resources\, in particular various typ
 es of solar cells. In parallel he researches hybrid molecular/non-molecula
 r systems\, focusing on understanding and controlling electronic transport
  across (bio)molecules. He heads WIS' Alternative\, sustainable energy res
 earch initiative.\n\nLight refreshments will be available after the presen
 tation.\n
