Purpose: The aim of this work is studying surface topography and optical properties of organic thin films of TiOPc and PTCDA blends deposited by thermal vacuum evaporation. Design/methodology/approach: Thin films of blends of organic materials are provided as donor/acceptor couples in bulk heterojunction based organic solar cells. Thin films of TiOPc - PTCDA mixture have been deposited by thermal vacuum evaporation from one source with various ratios of blends components and deposition rates used. Both the chemical composition and technological parameters of the deposition process have appeared to influence on optical properties, UV-Vis absorption spectra in particular, and surface morphology of the as-prepared thin films. The paper reveals the methodology of deposition thin films of TiPc-PTCDA donor/ acceptor blends and the influence of deposition parameters on their properties. Findings: Thin films of such blends can be used for the research on the planar heterojunction solar cells based on donor-acceptor couple active layers. Results of these investigations suggest that blends of TiOPc and PTCDA can be suitable materials for preparing organic photovoltaic devices. Research limitations/implications: Deposition parameters and proportions of the blend components used determine the properties of TiOPc/PTCDA thin films. Originality/value: The goal of this paper is also to define relations connecting the surface morphology and optical properties of thin films of TiOPc-PTCDA blend prepared with their composition and parameters of the evaporation process.
