“…The commercial TiO 2 nanopowders (P-25, Degussa AG Company, Germany, with 80% anatase, 20% rutile) exhibited a surface area of 50 m 2 g −1 [32]. In this study, the surface area of the anantase nanoflower was superior to various types of TiO 2 nanostructures such as the anatase nanoparticles (82 m 2 g −1 ) [33], anatase nanorods (∼200 m 2 g −1 ) [26], anantase nanotubes (125-135 m 2 g −1 ) [34], brookite nanoflowers (81.7 m 2 g −1 ) [15], and mesoporous anantase beads (108 m 2 g −1 ) [35].…”

In the field of photovoltaic energy conversion, hybrid inorganic/organic devices represent promising alternatives to standard photovoltaic systems in terms of exploiting the specific features of both organic semiconductors and inorganic nanomaterials. Two main categories of hybrid solar cells coexist today, both of which make much use of metal oxide nanostructures based on titanium dioxide (TiO 2 ) and zinc oxide (ZnO) as electron transporters. These metal oxides are cheap to synthesise, are non-toxic, are biocompatible and have suitable charge transport properties, all these features being necessary to demonstrate highly efficient solar cells at low cost. Historically, the first hybrid approach developed was the dye-sensitized solar cell (DSSC) concept based on a nanostructured porous metal oxide electrode sensitized by a molecular dye. In particular, solid-state hybrid DSSCs, which reduce the complexity of cell assembly, demonstrate very promising performance today. The second hybrid approach exploits the bulk heterojunction (BHJ) concept, where conjugated polymer/metal oxide interfaces are used to generate photocurrent. In this context, we review the recent progress and new concepts in the field of hybrid solid-state DSSC and BHJ solar cells based on TiO 2 and ZnO nanostructures, incorporating dyes and conjugated polymers. We point out the specificities in common hybrid device structures and give an overview on new concepts, which couple and exploit the main advantages of both DSSC and BHJ approaches. In particular, we show that there is a trend of convergence between both DSSC and BHJ approaches into mixed concepts at the borderline which may allow in the near future the development of hybrid devices for competitive photovoltaic energy conversion.

“…[19] A very low conversion efficiency has been reported for nano-brookite solid-state DSSCs. [20] To the best of our knowledge, the only report on brookite-based classical DSSC was from Yanagida et al [21] who obtained an efficiency of 4.1 %. However, these authors did not use pure brookite, but a commercial mixture of 75 % brookite and 25 % anatase.…”

Brookite TiO(2) nanoparticles have been synthesized at low temperature by a soft solution growth method and have been used as building blocks to prepare pure brookite nanoparticle porous films. The film brookite structure was confirmed by XRD and Raman spectroscopy. By spectrophotometry, it was shown that the films had a direct band gap of 3.4 eV. After sensitization by the N719 dye, efficient cells have been produced. A best overall conversion efficiency of 5.97%, without a scattering layer, was found for the larger TiO(2) starting nanoparticles. The cell open-circuit voltage was improved compared with that of anatase cells and a lower electron diffusion coefficient was found in the photoanodes made of smaller brookite particles. Lanthanum-doped brookite nanoparticle films were also studied. They showed a marked decreased in the amount of dye loading, and hence, the solar cells had a reduced current density that was not compensated for by the increased open-circuit voltage of the cells.
