Dye-sensitized solar cells based on anatase- and brookite-TiO: enhancing performance through optimization of phase composition, morphology and device architecture.

Herein, we demonstrate an optimization of dye-sensitized solar cells (DSSCs) through the development of single-layer and double-layer configurations. Focusing on the incorporation of brookite and anatase phases in varying ratios, the study aims to determine the optimal composition for enhanced photovoltaic performance. The active layer, composed of anatase- and brookite-TiOnanoparticles, is further modified with a scattering layer comprising a mixture of anatase nanoparticles and brookite-TiOin the form of nanocube or rice-like particles.
