Review effect of various types of dyes and structures in supporting performance of dye‐sensitized solar cell TiO ₂ ‐based nanocomposites

Abstract

The energy demand for supporting the activity of human life is increasing where fossil fuels decreasing sharply every year and have an impact on increasing CO 2 emissions in the environment. An alternative solution for providing practical energy needs is using renewable energy such as solar cells. For environmentally friendly, economical, and efficient concepts, dye-sensitized solar cell (DSSC) is a promising alternative for the photovoltaic field. The performance of a DSSC depends on many factors, such as electron collection at the photoanode, photoanode light-harvesting efficiency, and others. In this review article, we observe the influence of synthetic and natural dye materials on light-harvesting efficiency at photoanodes. The chemical structure of dyes plays an essential role in increasing photon absorption, thereby increasing electron injection and conversion efficiency. In addition to dyes, we also reviewed the influence of the shape of the DSSC structure, namely the sandwich, monolithic, and honeycomb structures, on the performance of DSSCs.This approach helps develop a narrative about the potential and relationship of dyes and structure in increasing efficiency as a guide for synthesizing new materials in the future.

Theoretical study on dye-sensitized solar cells using graphene quantum dot and curcumin, pahthalocyanine dyes

“…Hence, the efficiency of DSSC is low. Consequently, the GQD/Pc and 2GQD/Pc are the promising nanocomposites to be used as a sensitizer for DSSC [33].…”

Efficiency and stability improvement of natural dye‐sensitized solar cells using the electrospun composite of TiO 2 nanofibres doped by the bio‐Ca nanoparticles

“…Although synthetic dyes as sensitizers in DSSCs provide higher performance and durability than natural dyes, they suffer from several limitations, including adverse effects on the environment, the high cost of noble metals, and a complex synthesis process. Hence, extensive studies have been performed on natural dyes as viable alternatives to synthetic dyes because of their availability, environmentally friendly, cost‐effective, and easy preparation techniques 6,7 . On the other hand, the structure and morphology of semiconductor nanocrystals play a decisive role in the DSSCs performance 8,9 .…”

Designing of potential materials for solar‐hydro electricity generation: Preparation of novel nano‐structured films via thermodiffusion and polymerization methods

“…9 Usually, a DSSC contains a nanostructured titanium dioxide (TiO 2 ) electrode that was modified by a dye invented on a transparent conducting oxide (TCO), platinum wire as counter electrode, and a solution as electrolyte with a dissolved iodide ion/triiodide ion redox couple that is placed between the electrodes. 10 In a DSSC one of the approaches to facilitate electron recombination is the presence of nanocrystalline TiO 2 coating. 11 In a DSSC, positive properties of oxide films on a TiO 2 electrode have been investigated for various compounds such as Al 2 O 3 , SiO 2 , ZrO 2 , etc.…”
