 âtel\nAbstract: In the first part of the presentation\, we will show how 
 photovoltaics (PV) is on its way to become the primary electricity source\
 , and possibly the primary energy source by 2050-2060\, based on improveme
 nts in terms of performance\, material usage and energy pay-back time\, an
 d of course market demand and decarbonisation needs. Then\, we’ll discus
 s further evolution of the silicon technology (95% of the market)\, in par
 ticular when using silicon cells with various types passivating contacts\,
  which allow for a significant voltage increase of the solar cells. We’l
 l illustrate the trend with some of the work performed by EPFL and CSEM in
  Neuchâtel\, part of it implemented now in new European solar cells and m
 odule production lines. We will comment on how the efficiency learning cur
 ve could be extended\, in particular with the approach of tandem perovskit
 e/silicon solar cells\, where EPFL and CSEM recently achieved a certified 
 laboratory cell efficiency of 31.3%. Finally\, we will present many exampl
 es showing how photovoltaics goes well beyond standard applications\, with
  the emergence of “transformative PV” for the building sector or of sp
 ecialty modules applied in mobility or stratospheric applications.\n\nBiog
 raphy: Prof. Christophe Ballif is director of the Photovoltaics and Thin-F
 ilm Electronics Laboratory @ EPFL and of the Sustainable Energy Center @CS
 EM and\, which specializes in research and technology transfer along the v
 alue chain of photovoltaics and energy systems. With his teams\, he has co
 ntributed to numerous innovations\, products and start-up in the field of 
 photovoltaics and energy (PV) and collaborates with close to 40 companies 
 in Switzerland and worldwide. His current research and industrialization i
 nterests include materials and manufacturing processes for PV\, high-effic
 iency crystalline and perovskite solar cells\, module technology and relia
 bility\, specialty PV products for building integration or mobility\, as w
 ell as all aspects linked to storage and management of energy systems. He 
 is (co-) author of more than 600 scientific papers and of numerous patents
 . In 2016\, he received the prestigious Becquerel award for his contributi
 on to the field of Photovoltaics and he is an elected member of the Swiss 
 Academy of Engineering Sciences.
