Hydrothermal Synthesis of CdS Nanoparticle-Decorated TiO<SUB>2</SUB> Nanobelts for Solar Cell

Abstract

We fabricated a solar cell using a hybrid film consisting of CdS nanoparticle-decorated TiO2 nanobelts, which were synthesized via a modified alkaline hydrothermal method. The hybrid film is flexible and contains homogeneous CdS nanoparticle light absorbers. Furthermore, the type II heterostructure of CdS/TiO2 facilitates charge separation in the CdS nanoparticle-decorated TiO2 nanobelts. The solar cell demonstrated a light-electricity power conversion efficiency of 2.52%. Next, we deposited the CdS nanoparticle-decorated TiO2 nanobelts onto a ZnO nanowire array forming an antireflective hybrid structure. The power conversion efficiency of the cell with the hybrid photoanode reached 2.84%.

Facile Hydrothermally Synthesized a Novel CdS Nanoflower/Rutile-TiO2 Nanorod Heterojunction Photoanode Used for Photoelectrocatalytic Hydrogen Generation

“…Besides these methods and achievements, the hydrothermal method is another suitable method that has been employed to continuously amend the fabrication of one-dimensional (1-D), two-dimensional (2-D), or three-dimensional (3-D) nanostructures for the enhancement of the physicochemical properties of photocatalysts; accordingly, many reports on hydrothermally deposited CdS/TiO 2 heterojunctions are available. − However, to the authors’ knowledge, a study has not yet been conducted on the grafted of hydrothermally synthesized CdS nanoflowers (NFs) onto rutile (R)-TiO 2 nanorods (NRs) for which ethylenediamine (EDA) was used as both the template agent and the co-ordination agent. Furthermore, this grafting process is use to convert a crystal into an NF in the presence of the hydrothermal process.…”

Mechanistic aspects of biogenic synthesis of CdS nanoparticles using Bacillus licheniformis

“…In recent years, the biosynthesis of semiconducting nanoparticles such as cadmium sulfide (CdS) nanoparticles have acquired considerable interest due to their potential application in the field of solar cells, biosensors and fluorescent probe for medical purposes [1][2][3][4]. As physiochemical and optoelectronics properties of nanomaterials are size dependent, so researchers have adapted many different methods for synthesis of semiconductor nanoparticles of different sizes by means of microwave irradiation, chemical methods, hydrothermal micro-emulsion, sol-gel and photoetching, which mainly involve the use of large setup and huge cost [5][6][7][8][9][10].…”

Synthesis and characterization of ternary nanocomposites of TiO2/rGO/CdS as an efficient catalyst for photo‐degradation of methyl orange

“…[5][6][7] Recently, incorporation of TiO₂ with low-bandgap semiconductor CdS has become one of the most important chalcogenide materials with a bandgap lying in the visible region ($2.42 eV) at room temperature, which is used in many applications such as solar cells, light emitted diodes, optoelectronic devices, and photocatalysts. [8][9][10][11] Various researchers have already proposed that composites based on CdS and TiO₂ could improve photocatalytic performance because of low recombination rates. [12,13] Although these types of composites showed enhanced photodegradation performance.…”
