Purpose: The purpose of the work is to examine the influence of carbon nanotubes on the properties of dye-sensitised solar cells. Design/methodology/approach: The research material consisted of samples of glass plates with a conductive layer of FTO onto which layers were subsequently deposited of TiO2 titanium dioxide and titanium dioxide with an absorbed dye, a high conductivity PEDOT:PSS polymer with multi-walled carbon nanotubes, carbon black and graphite. Findings: The application of carbon nanotubes as one of electrodes in a dye-sensitised solar cell is significantly improving the effectiveness of the dye-sensitised solar cell being manufactured. Research limitations/implications: Carbon nanotubes are a good potential material for optoelectronics and photovoltaics. Practical implications: Carbon nanotube electrodes feature high conductivity and high visible light transmission. Originality/value: It is possible to change a structure of a dye-sensitised solar cell by replacing the commonly used platinum in a counter electrode with another electrode permeable for visible light made of a high conductivity PEDOT:PSS polymer with multi-walled carbon nanotubes.

Six polymethine dyes potentially suitable to use for dye sensitised solar cells and photocatalysts were studied. Electrochemical and spectral data have shown that LUMo levels of the dyes will provide high driving forces for electron injection ranging from 0.55 to 1.0 eV and only three dyes could be used with triiodide/iodide redox system applied for oxidised dye regeneration. The calculation method was explained in detail.

Zbadano sześć barwników polimetinowych potencjalnie nadających się do użycia do baterii słonecznych i fotokataliza torów sensybilizowanych barwnikami. Dane elektrochemiczne i spektralne wykazały, że poziomy LUMO barwników zapewnią wysokie siły napędowe dla przeniesienia elektronu, ale tylko trzy barwniki można użyć z systemem trijodek/jodek stosowanym do regeneracji barwnika. Metodę obliczeniową szczegółowo objaśniono.
