“…The synthesizing of single-phase CZTS thin films by sol-gel is difficult because of the formation of secondary phases such as Cu x S, ZnS, and SnS, along with non-uniformity of the grains. However, alternative approaches such as microwave-assisted synthesis have been reported to help overcome some of these challenges [106][107][108].…”

The importance and breadth of applications of the family of quaternary chalcogenides with the formula Cu2ZnSnSxSe(4−x) (CZTS/Se) where x = 0–4 are steadily expanding due to the tunable optoelectronic properties of these compounds and the Earth abundance of the elements in their composition. These p-type semiconductors are viewed as a viable alternative to Si, gallium arsenide, CdTe, and CIGS solar cells due to their cost effectiveness, Earth’s crust abundance, and non-toxic elements. Additionally, CZTS/Se compounds have demonstrated notable capabilities beyond solar cells, such as photoelectrochemical CO2 reduction, solar water splitting, solar seawater desalination, hydrogen production, and use as an antibacterial agent. Various routes have been explored for synthesizing pure CZTS/Se nanomaterials and significant efforts have been dedicated to reducing the occurrence of secondary phases. This review focuses on synthetic approaches for CZTS/Se nanomaterials, with emphasis on controlling the size and morphology of the nanoparticles and their recent application in solar energy harvesting and beyond, highlighting challenges in achieving the desired purity required in all these applications.

“…Thus, All CNT/P 3 HT samples with different ratios of P 3 HT show improved adsorption efficiency. In addition, it is expected to improve electrical conductivity, thereby enhancing the performance of photovoltaic applications [30,41]. But in the case of nanocomposites reinforced with silver nanoparticles (CNT/P 3 HT@Ag), as seen in Figure 6-B, a favorable boost in the maximum absorption intensity was observed for all prepared nanocomposite samples compared to pure P 3 HT polymer.…”

“…As a result, CNT/P 3 HT@Ag (0.5 P 3 HT) and CNT/P 3 HT@Ag (0.1 and then 0.3 P 3 HT) quench the PL intensity even more, reducing electron-hole recombination as a result of charge transfer between donor-acceptor materials. With these CNT/P 3 HT (0.5 of P 3 HT) and CNT/P 3 HT@Ag (0.1 of P 3 HT) samples, there is a high possibility of charge separation in the photoactive layer due to its strong PL quenching effect [30].…”

This research focuses on the synthesis of carbon nanotube (CNT) and Poly(3-hexylthiophene) (P3HT) (pristine polymer) with Ag doped (CNT/ P3HT@Ag) nanocomposite thin films to be utilised in various practical applications. First, four samples of CNT solution and different ratios of the polymer (P3HT) [0.1, 0.3, 0.5, and 0.7 wt.%] are prepared to form thin layer of P3HT@CNT nanocomposites by dip-coating method of Ag. To investigate the absorption and conductivity properties for use in various practical applications, structure, morphology, optical, and photoluminescence properties of CNT/P3HT @Ag nanocomposite are systematically evaluated in this study. In this regard, the UV/Vis/NIR spectrophotometer in the wavelength range of 350 to 700 nm is used to investigate the absorption, transmission spectrum, extinction coefficient (k) and refractive index of the samples prepared at room temperature. The XRD results indicate a slight increase in the crystallite size of the synthesized (CNT/ P3HT@Ag) nanocomposite compared to CNT/P3HT nanocomposite, which can be attributed to the better dispersion of the P3HT and its favorable wrapping around the carbon nanotube structures. FESEM results show that the Ag nanoparticles are acting as a bridge between the CNT and P3HT, creating a strong bond between the two materials that is strong enough to form thicker tubular structures. An appreciable increase in absorbance intensity (approximately 552 nm) is obtained by adding silver nanoparticles to the CNT/P3HT matrix at 0.5% of P3HT. Additionally, the prepared CNT/P3HT@Ag thin films show greater transmittance – more than 42%, 45%, 49%, and 48% for P3HT concentrations of 1%, 3%, 5%, and 7%, respectively. The preparation of the samples' extinction coefficient (k) and refractive index data show that the inclusion of silver nanoparticles to the CNT/P3HT nanocomposite matrix has a significant improvement over the previous samples (CNT/P3HT composite).
