“…17,18 Vertically aligned ZnO nanorods, formed by electrodeposition on a transparent conducting oxide, 24,25 as those shown in Fig. 2, have also attracted much attention for applications in solar cells 20,[26][27][28] and optoelectronic devices such as light emitting and laser diodes. 24,29,30 An important step of nanostructuring is an additional treatment of colloidal nanoparticles or nanorods for governing the electronic properties at the surface.…”

“…24,25 At any interface in a solar cell, physical and electrical phenomena largely influence the overall performance of the device at hand and, herein, the donorÀacceptor interface is the most critical one. As excitons are split close to that interface, the local morphology of the dye or polymer in the vicinity of the metal oxide is crucial for the device properties and, when optimized, can drastically increase the efficiency.…”

This paper focuses on the characterization of the ZnO/poly(3hexylthiophene) (P3HT) interfaces in nanostructured hybrid solar cells, aiming to elucidate the relationship between thermal treatment, local morphology, and device performance. An equivalent impedimetric model for the device is proposed, allowing us to extract information about the ZnO/P3HT interface morphology and its impact on the photovoltaic properties by comparing devices with and without nanopatterning. It is found that the influence of thermal treatment on performance lies solely in the interface, resulting from a different interfacial morphology of P3HT depending on which crystal direction of ZnO is present.

“…In DSSC, the electrons which are created at LUMO level of dye by absorption of photons from solar energy transfer to conduction band of wide band gap of TiO 2 and finally to the FTO electrode (Grätzel, 2004). Another similar semiconducting material which is extensively studying to utilize in the preparation of DSSC is Zinc Oxide because of its properties such as nearly equal to band gap as that of TiO 2 , great transparency and easy to fabricate with different nanostructured films (Baxter & Aydil, 2006). Recently, ZnO with various nanostructures: nanowires, nanorods, nanoflowers, or nanosheets have garnered attention due to excellent optical, electrical and structural properties (Kanmani et al, 2012;Plank et al, 2009).…”

Preparation and Characterization of Zinc Oxide Based Photoanode for Dye-sensitized Solar Cell using Delonix Regia Natural Dye Extract

As of late, research on the fabrication of natural dye-sensitized solar cells has been growing tremendously, largely due to its low cost and environmentally friendly nature. We have fabricated Zinc Oxide (ZnO) based Dye-sensitized Solar Cell (DSSC) using Delonix Regia, locally known as the Gulmohar flower natural dye extract. Zinc Oxide nanostructure films were allowed to grow on Fluorine-doped Tin Oxide (FTO) substrates via hydrothermal process. The seed layer for this was prepared by the spin coating method. The ZnO film's structure, topology, and optical properties were then studied using X-ray Diffraction (XRD), an Atomic Force Microscope (AFM) and an Ultraviolet Visible (UV-Vis) Spectrophotometer respectively. The X-ray results showed the hexagonal system structure of ZnO oriented along (101) planes. The effect of ethylene glycol on the structural property of ZnO film was also studied. The current voltage curve of DSSC showed the open circuit voltage and short circuit current of 360 mV and 80 µA respectively.
