Influence of carbon nanotubes on properties of dye-sensitised solar cells

摘要

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.
