Abstract: The aim of project is research on creating of organic solar cells (OSC) to be carried out for the first time in Bulgaria. Modeling and studying of OSC of various construction is being targeted and investigations on the technological methods for their production are being considered as well. In the formation of model constructions will be implemented: (i) dry» method where the component layers and the electrodes are formed by deposition in single vacuum cycle; and (ii) «wet» method - the active layers are formed by spin coating. The model constructions will be optimized by experimental and computational matrix methods. The dependence of the surface morphology on the composition, method of the layer production, type of substrate and electrodes and their influence on the formation processes and transport of the carriers will be investigated by SEM, TEM, NMR, Vis and NIR spectroscopy. In order to improve the conversion efficiency, processes and parameters of the models will be assessed by standard electrovoltaic measurements.
