Prof.dr. Tom Gregorkiewicz (Van der Waals-Zeeman Instituut, UvA): “Opportunities and challenges of (nano)photovoltaics”
abstract: In the first part of my talk I will presents basic concepts related to photovoltaic conversion and the underlying physics. I will discuss fundamental efficiency limits of solar cells and their origin. Subsequently, I will focus on use of silicon in photovoltaics and present the current state-of-the-art.
Following the more general part, I will move to opportunities which nanotechnology offers for overcoming the conversion limits. Then I will briefly present some interesting results on photon managements by Si nanocrystals, obtained recently in my group.
