TL;DR: In this article, a review of recent developments in the use of ZnO nanostructures for dye-sensitized solar cell (DSC) applications is presented.

TL;DR: The limitations and challenges of nanostructured materials while being used for solar cells, lithium ion batteries, supercapacitors, and hydrogen storage systems have also been addressed in this review.

TL;DR: H hierarchically structured ZnO films are reported as the photoelectrodes in DSSCs for the enhancement of energy conversion efficiency and coupling a photonic crystal layer to conventional TiO2 nanocrystalline films as the light scatterer succeeded in enhancing the light-harvesting capability of solar-cell photoelectROdes.

TL;DR: In this article, the authors classify the nanostructures into (1) nanoparticles, which offer large surface area to photo-electrode film for dye-adsorption, (2) core-shell structures, which are derived from the nanoparticles however with a consideration to reduce charge recombination by forming a coating layer, (3) one-dimensional nanstructures such as nanowires and nanotubes, which provide direct pathways for electron transport much faster than in the nanoparticle films, and (4) three-dimensional nanoparticles such as Nan

TL;DR: In this paper, zinc oxide (ZnO) has been explored as an alternative material in dye-sensitized solar cells with great potential, and the main reasons for this increase in research surrounding ZnO material include: 1) zinc oxide having a band gap similar to that for TiO2 at 3.2 eV, and 2) Znoxide having a much higher electron mobility ~ 115-155 cm2/Vs.
