This dissertation will scrutinize various photovoltaic technologies used in the world in connection with architecture. It will define most known, but also experimental materials and technologies. Additionally will try to explain how solar tracking can furthermore improve power harvesting potential and if it is economically justified. This report also investigates an idea of media façades and its possible connection with photovoltaics cells in building integrated PV technologies. The conclusion tries to answer the question what is the most efficient combination of active solar cells system for buildings façades as well as what determines the efficient use of photovoltaics from the point of view of architectural design.
