Purpose: The aim of the paper is to fabricate the dye-sensitized solar cells DSSC with carbon nanotube. Design/methodology/approach: The main aim this work was to improve the technological conditions of conventional dye solar cells by the application of nanostructured materials (MWCNTs) as one of the electrodes of the cell and to prove that the use of this type of nanomaterials increases the efficiency of dye solar cell electrodes. Findings: Carbon materials can be used as a counter electrode in dye-sensitized photovoltaic cells by replacing a costly platinum. Research limitations/implications: It has been found that due to the technology of developed conventional DSSC and cells with the carbon nanotubes, it is possible to lowering a production costs. It is advisable to take into account in the further experiments application of variables of different kinds of materials in the selected process parameters, and research for the use them in DSSC cells production. Practical implications: Presented in this paper results showed possibilities of modifying DSSC cells in terms of architecture, which should be correlated with the parameters of current-voltage and optical. DSSC cells are an interesting alternative to silicon solar cells. The stage of scientific research conducted around the world suggests that in the near future DSSC are fully commercially available. Originality/value: It was shown that the DSSC cells can be used as promising materials used in building-integrated photovoltaic.

W pracy przedstawiono wyniki badań struktury oraz składu chemicznego i fazowego wybranych powłok PVD naniesionych metodą reaktywnego rozpylania magnetonowego. Stwierdzono, że struktura powłok PVD wytworzonych metodą reaktywnego rozpylania magnetronowego jest złożona z dorbnych krystalitów. W większości przypadków występuje tekstura podwójna powłok (111) i (100) lub (110) i (311).

The paper presents investigation results of the structure, as well as of the chemical and phase compositions of the selected PVD coatings deposited by reactive magnetron sputtering method. It was found out that the structure of the PVD coatings deposited by reactive magnetron sputtering method is composed of fine crystallites. The duplex coating texture (111) and (100) or (110) and (311) occurs in most cases.
