“…On the other hand, a previous study reported that the Au core surrounded by SiO 2 and TiO 2 can boost efficiency to 5.52% [18], better than pure TiO 2 only. However, the efficiency obtained was small [10]. Other studies incorporating the core/multishell SiO 2 @Au@TiO 2 with SiO 2 synthesized from tetraethyl orthosilicate indicated the positive contribution of the multishell particles in the TiO 2 photoanode in increasing the efficiency to almost twice, compared to solely the TiO 2 photoanode [19][20][21].…”

“…However, nanomaterials with a size of less than H"50 nm, such as those used in the mesoporous layer of the DSSCs, cannot adequately either scatter or reflect sunlight [3]. Efforts have been concentrated on synthesizing materials based on SiO 2 as a scattering material either in the form of a core/shell [4] or as a microsheet [5] and SiO 2 extracted from Sidoarjo mud that can scatter the incoming light as these materials are incorporated into the mesoporous layer, such as simple core/shell materials [6,7], core/multishell materials [8][9][10], and silica microsheet [11,12]. These light-scattering materials usually have a low surface area, and thus, they can reduce light harvesting in the light-sensitized coating of the mesoporous layer.…”

A SYNERGISTIC ABSORPTION AND PLASMONIC EFFECT OF SiO2@Au@TiO2 IN A TiO2 PHOTOANODE FOR DYE-SENSITIZED SOLAR CELLS. A method for increasing the visible-light harvesting of a TiO2 anatase photoanode in dye-sensitized solar cells by incorporating plasmonic nanostructures was developed. Sidoarjo mud as the SiO2 source was used to successfully synthesized core/multishell SiO2@Au@TiO2, with varying amounts of Au (60, 90, and 120 mL). In addition, the core/multishell fractions in TiO2 paste were varied, i.e., 0.5%, 1%, and 5%. The UV–Vis spectrum shows that a more ripple spectrum at higher wavelengths is obtained with increasing Au content, as suggested by the presence of large Au nanoparticles; however, a similar value of efficiency is observed for all sample variations studied compared to a pure TiO2 photoanode. The incident photon-to-current efficiency reveals that all photoanodes containing the core/multishell SiO2@Au@TiO2 studied show somewhat broader and enhanced spectra for all studied wavelengths compared to the pure TiO2 photoanode, resulting from the synergistic effect between plasmonic nanostructures and the presence of silica that boost the absorption to higher wavelengths.

“…The photoanode is crafted from semiconductor nanostructures such as nanorods, nanowires, nanotubes, nanocones, and nanosheets. These are synthesized on conductive glass, which can be either transparent or opaque, to form the backbone of the cell [170]. The unique properties of these nanostructures, including their increased surface area, facilitate enhanced light absorption and electron transport, crucial for the cell's efficiency [171].…”

This review explores the extensive applications of plants in areas of biomimetics and bioinspiration, highlighting their role in developing sustainable solutions across various fields such as medicine, materials science, and environmental technology. Plants not only serve essential ecological functions but also provide a rich source of inspiration for innovations in green nanotechnology, biomedicine, and architecture. In the past decade, the focus has shifted towards utilizing plant-based and vegetal waste materials in creating eco-friendly and cost-effective materials with remarkable properties. These materials are employed in making advancements in drug delivery, environmental remediation, and the production of renewable energy. Specifically, the review discusses the use of (nano)bionic plants capable of detecting explosives and environmental contaminants, underscoring their potential in improving quality of life and even in lifesaving applications. The work also refers to the architectural inspirations drawn from the plant world to develop novel design concepts that are both functional and aesthetic. It elaborates on how engineered plants and vegetal waste have been transformed into value-added materials through innovative applications, especially highlighting their roles in wastewater treatment and as electronic components. Moreover, the integration of plants in the synthesis of biocompatible materials for medical applications such as tissue engineering scaffolds and artificial muscles demonstrates their versatility and capacity to replace more traditional synthetic materials, aligning with global sustainability goals. This paper provides a comprehensive overview of the current and potential uses of living plants in technological advancements, advocating for a deeper exploration of vegetal materials to address pressing environmental and technological challenges.

Human beings are attempting to take advantage of renewable natural resources by using solar cells. These devices take the sun’s radiation and convert it into electrical energy. The issue with traditional silicon-based solar cells is their manufacturing costs and environmental problems. For this reason, alternatives have been developed within the solar cell field. One of these alternatives is the dye-sensitized solar cell (DSSC), also known as Grätzel solar cells. DSSCs are a type of solar cell that mimics photosynthesis. They have a photoanode, which is formed by a semiconductor film sensitized with a dye. Some of their advantages include low-cost manufacturing, eco-friendly materials use, and suitability for most environments. This review discusses four important aspects, with two related to the dye, which can be natural or synthetic. Herein, only natural dyes and their extraction methods were selected. On the other hand, this paper discusses the nanostructures used for DSSCs, the TiO2 nanostructure being the most reported; it recently reached an efficiency level of 10.3%. Finally, a review on the novelties in DSSCs technology is presented, where it is observed that the use of Catrin protein (cow brain) shows 1.45% of efficiency, which is significantly lower if compared to Ag nanoparticles doped with graphene that report 9.9% efficiency.
