“…DSSCs represent a new class of solar cells, which are developed by the imitation of the photosynthesis process, by using low-price abundant materials, such as TiO 2 , sensitizers and simple manufacturing technology [234,235]. Since Gratzel and co-workers [234], many researchers have used the self-assembly approach for the design of many new nanostructured dyes and new sensitization methods for the development of DSSCs [236][237][238][239][240]. These approaches employ a series of new self-assembly strategies that eliminate expensive synthesis steps and realize a high yield [241][242][243][244][245].…”

In this paper, we survey recent advances in the self-assembly processes of novel functional platforms for nanomaterials and biomaterials applications. We provide an organized overview, by analyzing the main factors that influence the formation of organic nanostructured systems, while putting into evidence the main challenges, limitations and emerging approaches in the various fields of nanotechology and biotechnology. We outline how the building blocks properties, the mutual and cooperative interactions, as well as the initial spatial configuration (and environment conditions) play a fundamental role in the construction of efficient nanostructured materials with desired functional properties. The insertion of functional endgroups (such as polymers, peptides or DNA) within the nanostructured units has enormously increased the complexity of morphologies and functions that can be designed in the fabrication of bio-inspired materials capable of mimicking biological activity. However, unwanted or uncontrollable effects originating from unexpected thermodynamic perturbations or complex cooperative interactions interfere at the molecular level with the designed assembly process. Correction and harmonization of unwanted processes is one of the major challenges of the next decades and requires a deeper knowledge and understanding of the key factors that drive the formation of nanomaterials. Self-assembly of nanomaterials still remains a central topic of current research located at the interface between material science and engineering, biotechnology and nanomedicine, and it will continue to stimulate the renewed interest of biologist, physicists and materials engineers by combining the principles of molecular self-assembly with the concept of supramolecular chemistry.

“…Using non-fossil fuel sources, such as solar energy, provides an economically viable solution to combat climate change. The sun delivers approximately 13.6 TW of carbon-free energy to the Earth every hour, which exceeds the annual energy consumption of the entire human population, estimated at around 13 TW h. 1 Harvesting just a tiny fraction of this enormous energy amount could be sufficient to satisfy the entire global energy demand. 2 In this context, renewable solar photovoltaics (PV), as one model to convert solar energy directly into electricity, will play a key role in decarbonizing our energy production in the coming decades.…”

“…The function of the photo-anode is very important to convert light energy into electrical energy and is deposited in the conductive glass. Photo-anode is composed of a working electrode that had been coated with semiconductor materials [4] [5]. The photo-anode has a large surface area for the dye attached and good electron transport capability to achieve high energy conversion efficiency performance.…”

Natural dye is one of the important materials of DSSC which absorbs photons from the sun's rays and transmits the photoelectron. One of the natural dyes is dragon fruit dye. The characterization of the optical and electrical properties of a sensitizer DSSC used a UV-Vis spectrometer, FTIR spectrometer, and solar power meter. The absorption spectra of dragon fruit dye extracted were obtained by UV-Vis spectrophotometer, Fourier Transforms Infra-Red (FT-IR) was used to characterize the dye's components, and measure the radiated and transmitted sunlight by solar power meters. Result of UV-Vis absorbance, dragon fruit dye has the highest absorbance rate with a peak of 530 nm and bandgap of 2.09 eV, while the ZnO sensitized by dragon fruit dye has the highest absorbance rate with a peak of 535 nm and bandgap of 2.56 eV. From FT-IR spectrometer result shows that dye extracted from dragon fruit, and ZnO sensitized by dragon fruit dye contained C=O stretching vibrations at the peak of 1716 cm -1 , and the peak at 3423 cm -1 , and 3448 cm -1 shows the O-H stretching vibration. The C-O-C which corresponds to the esters group for dragon fruit's dye is observed. It is a part of anthocyanin and chlorophyll. Zinc oxide (ZnO) paste is coated on the Indium Tin Oxide (ITO) as the thin film is dipped in the dragon fruit dye extracted for 30 hours. A thin film is prepared as the working electrode and counter electrode. The characteristic of current and voltage (I-V) as electrical properties are measured by the solar power meter. The best efficiency of dragon fruit dye extracted is 0.03%, and it can absorb the light from the sun. The performances of the dye absorption spectrum on the surface area are important aspects to determine the efficiency of the solar cell. The dragon fruit dye extracted coated ZnO thin film could be used as a sensitizer since it will increase the correlation between the ZnO thin film and dye. And the last, it will improve the quality of solar cells as well. The dragon fruit dye has the potential a natural sensitizer in DSSC.
