 Panagiotis E. Keivanidis was born in Pireas, Greece in 1976. In the period of 1995 – 2000 he studied Chemistry at the Chemistry Department of University of Crete in Heraklion, Greece. In 1998 he completed his practical work in the industrial sector (SaniCot SA, Piraeus) and in 2000 he completed his Diploma Thesis in the Luminescence Group of Prof. A. Meijerink, at the University of Utrecht, the Netherlands. In 2001 he worked as a lab assistant in the Sol-Gel Lab of the Institute of Materials Science, at the National Centre for Scientific Research ‘Demokritos’ in Athens, Greece. In 2005 he received his PhD (magna cum laude) in Natural Sciences (doctor rerum naturalium) from Johannes Gutenberg University of Mainz in Germany for his studies on the electronic energy transfer processes in π-conjugated polymers, in the Solid State Chemistry Group of Prof. G. Wegner at the Max Planck Institute for Polymer Research (MPI-P). In the period of 2005 – 2008 he was a Research Associate in the Optoelectronics Group of Prof. Sir R. H. Friend in the Cavendish Laboratory at Cambridge, UK where he performed research on the development of low dark-current solution-processed organic photodetectors and on the study of perylene diimide derivatives as functional n-type materials in organic photodiodes and solar cells. In the period of 2008 – 2010 he was a Research Associate in the Group of Experimental Solid State Physics in the Blackett Laboratory at Imperial College London working with Prof. J. Nelson and Prof. D. D. C. Bradley. During his staying in London he performed transient absorption and delayed luminescence spectroscopic experiments (in the μs-ms time range), for correlating the efficiency of charge photogeneration and recombination in organic photovoltaic composites with their layer microstructure. He has been active in the attraction of funds for research (Laser Lab Europe, Royal Society) and for the establishment of research networks between Imperial College and external collaborators. He was a visiting scientist in the Chemical Physics Group, at the Chemical Centre of University of Lund, Sweden and in the Organic Optoelectronics Group at MPI-P. He is the author and co-author of more than 40 peer-reviewed articles appeared in international scientific Journals and he is the co-inventor in one international patent with SONY International (Europe), US Patent 7,683,363 (2010), EP1484379, AU 2004/202413, JP 2005/049824.

 In 2010 he established and lead the Device Technology & Chemical Physics Group at the CNST@PoliMi. During 2010-2014 he supervised four PhD students, two post-doctoral research associates, two Master students and two 3rd Year undergraduate students. Formally, he is a co-supervisor in a Marie Curie Initial Training Network (project DESTINY).

 In the period 05/2012 - 05/2014 he held an Intra European Marie Curie Fellowship (project DELUMOPV) and he served as a Marie Curie Ambassador for the dissemination of European scientific activities on the field of Organic Electronics in high schools of southern European countries (Spain, Greece, Portugal).

 In December 2013 Panos accepted an Assistant Professor position offered by the Department of Mechanical Engineering and Materials Science and Engineering of the Cyprus University of Technology, in Limassol, Cyprus (official starting date 01/09/2014, current e-mail:

 The Keivanidis research group is active in the electro-optical characterization of organic nanostructured materials to be used in organic photovoltaic (OPV) and photonic applications and it pays special attention on the elucidation of the structure-property-function relationships that dictate the performance of these systems. Emphasis is given on the development of experimental tools and fabrication protocols that can uncork the existing bottlenecks to the protection, the optimization and the sensitization of organic electronic devices (the prot.o.s. concept). Within this context, research projects are currently ongoing on:

i) the development of fullerene-free organic solar cells based on low-cost perylene diimide electron acceptors,

ii) the optimization of solid-state organic photon up-converters,

iii) the application of phosphorimetric spectroscopy techniques for the study of solution-processed barrier materials that aim to protect Organic Electonics,

iv) the correlation of delayed (in the μs time-scale) charge transfer luminescence in OPV composites with charge transport properties of the composites,

v) the identification of the limiting factors in power-generating and light-sensing devices with the use of transient photocurrent and transient photovoltage characterization measurements,

vi) the use of sol-gel protocols for the development of metal oxides to be used as charge extraction layers in power-generating and photo-detecting devices.
