Description
Summary:•Zn2SnO4 nanoparticles are synthesized by simple solvothermal route.•Mesoporous Zn2SnO4 electrodes are prepared introducing a suitable paste formulation.•Zn2SnO4 based photoanodes display superior transmittance.•Semi-transparent dye sensitized solar cells are fabricated using Zn2SnO4 photoanodes. Zinc Stannate (Zn2SnO4) nanoparticles are synthesized using solvothermal method. As synthesized nanoparticles are found to be in face centered cubic spinel structure confirmed by X-ray diffraction studies. Transmission electron microscopy images reveal that as synthesized Zn2SnO4 nanoparticle are of about 20 nm size. A paste containing as synthesized Zn2SnO4 nanoparticles is developed to prepare photoanodes to utilize in semi-transparent dye sensitized solar cells. As fabricated semi-transparent dye sensitized solar cells with dye adsorbed Zn2SnO4 based photoanodes demonstrate a photoconversion efficiency of 0.86%.
