Formation of Polymer Films in Organic Photovoltaic Systems

Abstract

The influence of elementary processes on the effectiveness of an organic semiconductor based photovol-taic cell designed for energy conversion is highly dependent on the active polymer layer structure. The most urgent task is, therefore, to develop experimental methods for forming films of organic semiconduct-ing polymers with various structures from thin (monolayer films) a few nanometers thick to multilayer ones up to a few micrometers thick. Research has indicated that the layer morphology of the films obtained (up to 350 nm thick) gives rea-son to postulate film structure and composition being dependent on the value of relative fluorescence vari-ation under the influence of a superimposed magnetic field. Moreover, the transmittance and absorption spectra of polymer films which in many ways define the architecture of a photovoltaic cell are highly de-pendent on the concentration of solutions in the 300-325 nm wavelength range.
