Tuning TiO2 Porosity of Multilayered Photoanode Towards Enhanced Performance of Dye Sensitized Solar Cell

In this paper, we prepared Titanium Dioxide (TiO2) based dye sensitized solar cells (DSSC). Downscaling of commercial TiO2 powder have been achieved by systematic ball milling carried out using home-made device. Thin films were and samples characterized XRD, SEM, UV-Vis I-V. The main objective work is to prepare (DSSC) N3 study the effect grain size inside photoanode layer on efficiency cell. UV-vis nanometer sized particles showed that energy gab has shifted towards lower wavelength in electromagnetic spectrum (blue shift), then optical band gap an indirect allowed transition. Energy calculations related quantum confinement effect. A sophisticated strategy for consisting tailoring monolayer, bilayer trilayer mixed multisized nanoparticles adopted investigated as DSSC electrodes. Our results can be substantially altered due designs particle distributions photoelectrode. maximum 0.5% was reached photoelectrode designed a with wide distribution from about 12 340 nm middle layer. approach light scattering submicrometer‐sized aggregates order interpret enhancement our over extending length transported wave hence promote acquiring thin film. relatively larger sizes afford both better packing increased capability incident wave, improves efficiency.
