Screen‐Printing of ZnO Nanostructures from Sol–Gel Solutions for Their Application in Dye‐Sensitized Solar Cells

Abstract: Diblock copolymers have been used in sol-gel synthesis to successfully tailor the nanoscale morphology of thin ZnO films. As the fabrication of several-micron-thick mesoporous films such as those required in dye-sensitized solar cells (DSSCs) was difficult with this approach, we exploited the benefits of diblock-copolymer-directed synthesis that made it compatible with screen printing. The simple conversion of the diblock copolymer ZnO precursor sol to a screen-printing paste was not possible as it resulted in… Show more

“…Sarkar et al investigated the use of diblock copolymers in ink formulation, in order to direct the shape and morphology of metal oxide nanostructures in thin films, where the sol-gel-based metal oxide formation was combined with the assembly of hydrophilic metal oxide precursor sols within the hydrophilic domain of self-assembled amphiphilic diblock copolymer mesophases [95]. They further investigated this approach in order to obtain several-micron-thick films containing tailored ZnO nanostructures required for dye-sensitized solar cell (DSSC) applications [96]. In their work, the sol-gel solution was first used to synthesize ZnO NPs of different sizes, which were then used to prepare the screen-printing paste containing poly(styrene-block-ethylene oxide) polymers.…”

“…A large part of research has been devoted to improve the materials through the incorporation of dopants and photosensitizers to harvest better the light and minimize electron-holes recom-bination [9][10][11][12][13][14] , but this form of hybrid nanostructure risks the formation of crystal defects which act as recombination centers and reduce an efficient charge transport. The electron transport through the nanostructure is crucial to achieve a good photon-toelectron quantum efficiency [15] .…”
