摘要: We integrate mesostructured titania arrays into dye-sensitized solar cells by replicating ordered, oriented one-dimensional (1D) columnar and three-dimensional (3D) bicontinuous gyroid block copolymer phases. The cell performance, charge transport, recombination are investigated. observe faster transport in 1D “wires” than through 3D arrays. However, owing to their structural instability, the surface area of wire is low, inhibiting performance. morphology, on other hand, outperforms current state-of-the-art mesoporous nanoparticle films.
