In this lecture we will review basic principles of primary events in natural photosynthesis occurring in plants and bacteria. We will put the claims about remarkable efficiency of photosynthetic light-harvesting in the context of efficiencies of man (and woman) made photovoltaic materials, and in the context of organism’s struggle for survival. This will reveal as naïve the assumption that three billion years of evolutionary optimization delivered a perfect natural photosynthetic machinery to be just copied by modern nanotechnology. We will suggest which principles and components of natural...

Abstract: The availability of ultrashort laser pulses enabled the development of techniques for coherent generation and detection of broadband terahertz pulses. These can be efficiently applied for spectroscopic measurements including terahertz transmission and emission spectroscopy and pump-probe experiments. The high probing frequency enables investigation of charge transport on nanoscale distances. This makes terahertz spectroscopy suitable for studies of nanostructured materials.
In this talk, an overview of basic experimental techniques utilizing time-domain...
