The invention discloses a preparation method of dye-sensitized
solar cell platinum loaded
silicon carbide counter electrodes. The preparation method comprises the steps of (1) preparing Pt-SiC composite counter
electrode materials: respectively preparing the H2PtCl6 solution and the SiC alcoholic solution, conducting ultrasonic mixing on the H2PtCl6 solution and the SiC alcoholic solution, adjusting the pH value, conducting
microwave heating after
ultrasonic dispersion is carried out, conducting washing, filtering and
drying, conducting heat treatment in the
inert atmosphere, and obtaining the Pt-SiC composite counter
electrode materials, and (2) building a Pt-SiC counter
electrode thin film: washing and
drying FTO conducting glass, adding the Pt-SiC composite counter electrode materials into a dispersing agent, conducting dispersing
processing to obtain a counter electrode catalytic material
sizing agent,
coating the conducting glass with the counter electrode catalytic material
sizing agent to form the Pt-SiC counter electrode thin film, and conducting heat treatment in the
inert atmosphere to obtain the
platinum loaded
silicon carbide counter electrodes. The preparation method is low in building cost, simple in operation process, low in
energy consumption,
environmentally friendly and high in compatibility with the photo-
anode preparation technology. The
precious metal Pt electrodes can be replaced by the Pt loaded
silicon carbide counter electrodes, and the Pt loaded
silicon carbide counter electrodes can be applied to dye-sensitized
solar cell devices.
