Performance of CoTiO3 as an oxide perovskite material for the light scattering layer of dye-sensitized solar cells

摘要: Light scattering layers can play an essential role in the transport characteristics of charge carriers and photovoltaic performance dye-sensitized solar cells (DSSCs). Perovskite oxide materials have recently attracted considerable attention as light due to their optical structural properties. Herein, we synthesized TiO2–CoTiO3 composites with a facile room temperature sol–gel procedure for use layer photoanode DSSC devices. were applied monolayer photoanodes bilayered films on nano-TiO2 photoactive layer. Microstructural investigations composite showed bimodal texture consisting CoTiO3 coarse TiO2 fine particles. containing exhibited higher property lower dye adsorption amount compared control pristine electrode. Photovoltaic metrics fabricated devices different contents mono- configurations recorded under simulated AM 1.5 sunlight, suggesting that improved presence Interestingly, no difference operation was achieved (i.e., photoconversion efficiency (PCE) 7.46% 7.67% devices, respectively). However, PCEs are about 80% than device without
