Sb2S3 nanoparticles through solution chemistry on mesoporous TiO2 for solar cell application

A facile room temperature (27 °C) chemical route, namely successive ionic layer adsorption and reaction (SILAR) method is used to deposit antimony trisulphide (Sb2S3) nanoparticles on mesoporous titanium dioxide (TiO2). The method facilitates linker free approach to deposit the size tuned nanoparticles. The synthesized TiO2/Sb2S3 structure on a FTO (fluorine doped tin oxide coated glass substrate) was used as a photoanode with polysulphide as liquid electrolyte and platinum coated FTO as back contact to construct the photovoltaic device. The photovoltaic performances have been tested under light illumination with standard solar simulator condition (AM 1.5G, 10 mW/cm2) and photovoltaic parameters are discussed.
