In this study, five new pyrazolyazo pyrazole dyestuff syntheses are reported. For this purpose, 5‐amino‐4‐arylazo‐3‐methyl‐1H‐pyrazoles were diazotised and coupled with 3‐amino‐5‐hydroxy‐1H‐pyrazole. Fourier Transform–infrared, ultraviolet‐visible and proton nuclear magnetic resonance spectroscopy were used to investigate the properties of aminopyrazole‐based dyes obtained in this study. The maximum absorption wavelengths of these dyes in various solvents were determined. The theoretical calculations of the molecules in the ground state were performed with the density functional theory/Becke 3‐parameter and Lee–Yang–Parr/6‐311G(d,p) method by using the Gaussian 0.9 W program. The results were compared with the corresponding experimental data. Acid‐base and substituent effects on the absorption spectra of dyes were also examined and reported.

“…Finally, reference [58] reports the development of a DSSC with difunctionalized dyes, which are based on isophthalic acid or 4-tert-butylcalixarene as a framework and N-Ndialkylaniline as electro donator connected to thiophene as π-spacer. For this research, three cases are presented to study (AT-L, Cx-2-AT-L, and Ft-2-AT-L), and after performing the corresponding tests, it is concluded that the Cx-2-AT-L case is the one that shows the highest efficiency with 5.20%.…”

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.
