AI Article Synopsis

  • A bi-layer photoanode for dye-sensitized solar cells (DSSCs) was created using TiO hollow spheres (THSs) as a light-scattering layer and P25/multi-walled carbon nanotubes (MWNTs) as an underlying layer.
  • The THSs were made using a specific method that enhances light scattering, while MWNTs combined with P25 aimed to boost the electron transport efficiency.
  • This design improved the power conversion efficiency of the DSSC to 5.13%, which is a 14.25% increase compared to DSSCs made with only P25.

Article Abstract

Abstract: A bi-layer photoanode for dye-sensitized solar cell (DSSC) was fabricated, in which TiO hollow spheres (THSs) were designed as a scattering layer and P25/multi-walled carbon nanotubes (MWNTs) as an under-layer. The THSs were synthesized by a sacrifice template method and showed good light scattering ability as an over-layer of the photoanode. MWNTs were mixed with P25 to form an under-layer of the photoanode to improve the electron transmission ability of the photoanode. The power conversion efficiency of this kind of DSSC with bi-layer was enhanced to 5.13 %, which is 14.25 % higher than that of pure P25 DSSC.

Graphical Abstract: A bi-layer composite photoanode based on P25/MWNTs-THSs with improved light scattering and electron transmission, which will provide a new insight into fabrication and structure design of highly efficient dye-sensitized solar cells.

Dye-sensitization is a promising strategy to improve the light absorption and photoactivity abilities of wide-bandgap semiconductors, like TiO. For effective water-splitting photoanodes with no sacrificial agents, the electrochemical potential of the dye must exceed the thermodynamic threshold needed for the oxygen evolution reaction. This study investigates two promising organic cyanoacrylic dyes, designed to meet that criterion by means of theoretical calculations.

Hydrogen-substituted graphdiyne (HsGDY) is a two-dimensional material with an sp-sp carbon skeleton featuring a band gap and a porous structure that enhances ion diffusion. In previous reports, HsGDY growth was limited to metal substrates such as Cu, which then required transfer. Here, we developed a sandwich method that allows HsGDY to be grown directly on the target substrate.

Background: The demand for sustainable energy solutions has increased interest in natural microalgal dyes as photosensitizers in dye-sensitized solar cells (DSSCs). This study addresses the critical issue of maximizing dye integrity and yield during extraction, particularly the degradation that occurs at temperatures above 60 °C. Our investigation of dye extraction from Asterarcys quadricellulare and Scenedesmus sp.

The efficient functioning of dye-sensitized solar cells (DSSCs) is governed by the interplay of three essential components: the semiconductor, the dye, and the electrolyte. While the impact of the electrolyte composition on the device's performance has been extensively studied in n-type DSSCs, much less is known about p-type-based devices. Here, we investigate the effect of potential-determining ions on the energetics and stability of dye-sensitized NiO surfaces by using electrochemical, ab initio molecular dynamics simulations, and ab initio electronic structure calculations.
