University of Ljubljana (UL) - Laboratory of Photovoltaics and Opto-electronics

The Laboratory of Photovoltaics and Optoelectronics at the Faculty of Electrical Engineering, University of Ljubljana is the central research group for photovoltaics in Slovenia. Numerical modelling and simulations along with characterization of materials and devices for photovoltaics are the focus of their research activities. Current research interests are on one hand devoted to optical modeling and simulations of thin film structures incorporating smooth and textured interfaces for profound analysis of light trapping schemes in the new thin film solar cell devices. On the other hand they work intensively in the field of three-dimensional electrical modeling of solar cells and modules and analysis of electrical losses there in.

The group counts 18 members and it is headed by Dr. Marko Topic, Full Professor of Elec. Eng., who is a very active member of European Photovoltaic Technology Platform (, where he acts as a member of the Steering Committee and of the WG3 “Science, Technology and Applications”, as well as the Slovenian representative in “National Programme Mirror Group” and also a member of the Steering Committee. He is also the chairman of Slovenian Photovoltaic Technology Platform.
