Applications of bile acids (BAs) and bile salts (BSs) in the nanotechnology of functional materials are described. The exceptionally strong solubilization and dispersion power of BAs/BSs is a key factor for the solubilization of dyes, drugs, and polymers for electronic, optical, and biomedical devices, fabrication of composites, based on carbon nanotubes, graphene, diamonds, quantum dots, and polymers for applications in energy storage devices, coatings for corrosion protection of metals, sensors and electronic devices. BAs/BSs have attracted attention for synthesis, design, and surface modification of advanced materials. BAs/BSs are used as reducing, capping, chelating and dispersing agents for the synthesis of nanoparticles of metals and alloys, and low temperature synthesis of stoichiometric nanostructured complex oxides. BAs/BSs exhibit unique selfassembly properties, which are successfully used for the template synthesis of functional nanoparticles of controlled shapes. Particularly important are applications of BAs/BSs in the fabrication of dye sensitized solar cells with enhanced efficiency. Electrochemical strategies are discovered for the deposition of BA films and composites. Of particular interest are the unique gel-forming properties of BAs/BSs, which provide a basis for the synthesis of nanoparticles of controlled size and fabrication of novel materials with advanced functionality.

“…3 Dye-sensitized solar cell (DSSC) is one of the latest innovations of photovoltaics that are economical, efficient, and environmentally friendly. [5][6][7] In general, DSSC consists of photoanode, sensitizer, the counter electrode (CE), and electrolyte pair (I À =I À 3 ). 5,8,9 The working principle is based on light absorption by a dye and then injecting electrons into the semiconductor's conduction band.…”

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.

Three D‐A’‐π‐A type of metal‐free organic sensitizers, which are based on naphtho [2,3‐d] [1‐3] triazole entity as auxiliary acceptor and several dithienoheterocycles (cyclopentadithiophene, dithieno[3,2‐b:2’,3’‐d]silole, dithieno[3,2‐b:2’,3’‐d]pyrrole) as π‐conjugated bridge, are investigated using density functional theory (DFT)/time‐dependent DFT methods. First, the influence of different π‐bridges on the photovoltaic properties in three dyes is analyzed by mainly studying geometry structures, spectral characteristics, electron injection, dye regeneration, and charge difference density to explain highest performance of HJL‐3. Second, molecular design of introducing graphene quantum dots (GQDs) is carried out, and the results find that HJL‐3@GQDs display better photoelectric performance because GQDs have a positive impact on some parameters (such as light‐harvesting efficiency, electron injection amounts, dipole moment, and so on) upon introducing GQDs. This work provides a reasonable explanation for the experiment and a way to regulate performance of dye‐sensitized solar cells.
