“…That is, the dark currents of the DSC-2 and DSC-3 are larger than that of DSC-1. 9 However, TiO 2 scattering layer can improve the J sc from 14.99 (DSC-1) to 16.91 (DSC-2) and 18:55 mA Á cm À2 (DSC-3), which could be attributed to the increased dye adsorption and photo-induced electron. Both of the dye adsorption increase and light scattering enhancement could result in higher J sc .…”

“…1,2 In order to improve the photovoltaic performance of DSSCs, many fundamental and experimental researches have been proposed to optimize solar cell materials, including photosensitizers, [3][4][5] photoanode, [6][7][8][9][10][11] redox electrolyte 12 and counter electrode. 13 Among these methods, an e®ective way to improve the photoelectric conversion e±ciency was applied in the photoanode¯lm with the superior light scattering performance in DSSCs.…”

The sub-microspheres play multiple roles in enhancing dye adsorption and light-scattering to improve the performance of dye-sensitized solar cells (DSSCs). In this work, the well-de¯ned TiO 2 sub-microspheres with anatase granular-like nanocrystals are prepared in high yield by combining hydrolytic process with solvothermal treatment. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) results indicated that plenty of rhombic nanoparticles with $ 18 nm diameter having mutual contacts to neighboring nanoparticles were densely selfassembled into sub-microspheres, and abundant mesopores existed in the whole sub-microspheres with superior light scattering ability. The appropriate pore diameter and relatively high speci¯c surface area of the as-obtained sub-microsphere result in a higher dye adsorption. As expected, by using the sub-microspheres as a scattering layer, a higher photovoltaic conversion e±ciency of 10.15% is obtained for DSSCs.

“…400 nm anatase particles) on top of the dye-sensitized layer to reflect the unabsorbed photons back into the absorbing film [106] and thus increase the optical path length within the cell. These include mesoporous TiO 2 beads, [109] hierarchical TiO 2 spheres, [110][111][112] hexagonal TiO 2 microplates, [113] mesoporous TiO 2 aggregates, [114] mesoporous fibers, [90,103,115,116] and TiO 2 hollow spheres. The light scattered from a scattering layer made of these particles back into the cell acquires a tapered Lambertian diffuse-reflectivity profile.…”

The knowledge of dye-sensitized solar cells (DSCs) has expanded considerably in recent years. They are multiparameter and complex systems that work only if various parameters are tuned simultaneously. This makes it difficult to target to a single parameter to improve the efficiency. There is a wealth of knowledge concerning different DSC structures and characteristics. In this review, the present knowledge and recent achievements are surveyed with emphasis on the more promising cell materials and designs.
