“…In the last few years, alternative energy sources to fossil fuels have been one of the most studied fields in scientific research. In this regard, researchers embarked on the design of new technologies able to harvest energy, where solar cells were pivotal for the success of this area [ 216 , 217 ]. Among solar cells, a particular kind has received growing attention, due to its cost-effectiveness and resource-unlimited characteristics: dye-sensitized solar cells (DSSCs).…”

Anthocyanins are widespread and biologically active water-soluble phenolic pigments responsible for a wide range of vivid colours, from red (acidic conditions) to purplish blue (basic conditions), present in fruits, vegetables, and coloured grains. The pigments’ stability and colours are influenced mainly by pH but also by structure, temperature, and light. The colour-stabilizing mechanisms of plants are determined by inter- and intramolecular co-pigmentation and metal complexation, driven by van der Waals, π–π stacking, hydrogen bonding, and metal-ligand interactions. This group of flavonoids is well-known to have potent anti-inflammatory and antioxidant effects, which explains the biological effects associated with them. Therefore, this review provides an overview of the role of anthocyanins as natural colorants, showing they are less harmful than conventional colorants, with several technological potential applications in different industrial fields, namely in the textile and food industries, as well as in the development of photosensitizers for dye-sensitized solar cells, as new photosensitizers in photodynamic therapy, pharmaceuticals, and in the cosmetic industry, mainly on the formulation of skin care formulations, sunscreen filters, nail colorants, skin & hair cleansing products, amongst others. In addition, we will unveil some of the latest studies about the health benefits of anthocyanins, mainly focusing on the protection against the most prevalent human diseases mediated by oxidative stress, namely cardiovascular and neurodegenerative diseases, cancer, and diabetes. The contribution of anthocyanins to visual health is also very relevant and will be briefly explored.

“…This trait provides a signi cant advantage over sensible heat storage materials, which require large temperature variations and substantial storage volumes [7,8]. PCMs can e ciently store and release energy within smaller temperature ranges, making them highly effective for applications requiring precise thermal regulation and compact storage solutions [9,10]. Their superior thermal e ciency and compactness are crucial for enhancing the performance and feasibility of TES systems in various applications, from building climate control to industrial heat management [11].…”

Phase change materials (PCMs) have emerged as an intriguing option for the storage of thermal energy because of their remarkable capacity to store latent heat. However, the practical application of these materials is hindered by their low thermal conductivity and limited photo-absorbance. For this investigation, graphene nanoplatelets (GNP) and multiwall carbon nanotubes (MWCNT) hybrid nanoparticles were disseminated in RT-54HC organic PCMs at different weight fractions. The nanoparticles were incorporated into the base PCMs using a melt blending technique. Based on the findings, one combination of GNP to MWCNT in a 0.25:0.75 ratio has shown the highest thermal conductivity, with an increase of 30 % (0.28 Wm-1K-1) compared to other hybrid combinations. This breakthrough could potentially open new avenues in the field of thermal energy storage. The chemical stability of the hybrid nanoparticle dispersed composites was assessed through FTIR analysis. In addition, the composites exhibited excellent thermal stability, maintaining their structural integrity even at temperatures as high as 300℃. The melting temperature of the composites also showed minimal variation. Based on the evaluation of latent heat enthalpy, the organic PCM known as base RT-54HC demonstrated a heat storage capacity of 180 J/g. However, the composites exhibited a slight decrease in latent heat with increasing nanoparticle weight fraction. In addition, the composite with added hybrid nanoparticles demonstrated an increase in optical absorbance, accompanied by a decrease in transmissibility. Therefore, the hybrid nano-enhanced composites have demonstrated enhanced thermo-physical properties, making them not only suitable but also highly promising for use in applications with mid-range melting temperatures.

“…However, flexible DSSC technology suffers from having low conversion efficiency stemming from issues such as poor interparticle connectivity and limited charge transfer in the photoanode [4]. This was due to the sintering temperature in manufacturing flexible DSSC being low (120 -150 °C), to accommodate the plastic substrate that has low thermal stability [5]. Therefore, various effort has been made to address the issue plaguing the flexible low temperature DSSC and enhance the conversion efficiency to be higher than the current highest of around 8% [3].…”

Flexible dye sensitized solar cells (DSSCs) possess multiple advantages with wide application and good commercialisation potential. However, the low conversion efficiency of the technology from poor charge transfer and interparticle contact has limited their utilisation. Thus, the research aims to enhance the performance of flexible plastic-based titanium dioxide (TiO2) film via the formation of TiO2-bismuth (Bi) ink for screen-printing of DSSC photoanode film. The implementation of Bi nanoparticles as sintering aid has managed to improve the interparticle contact in the photoanode film with neck formation at the TiO2-Bi interface. This phenomenon has also led to the lowering of resistance values by 57 - 65% with charge transfer resistance of 11.72 kΩ.cm2 and series resistance of 38.28 kΩ.cm2 for the TiO2-Bi photoanode. The recombination reactions were also reduced with longer electron lifetime of 0.0036 ms and enhanced charge transfer. The research has managed to prepare TiO2-Bi ink that would be suitable for the fabrication of flexible DSSC photoanode film via screen printing. Hence, the outcome of the research could potentially lead to the development of highly efficient flexible low temperature DSSC and enhance their commercialisation potential.
