New technologies need environmental and economic cooperation. Energy consumption is fundamental to human survival, making sustainable development imperative. When discussing energy production, renewable resources such as solar and wind energy are chosen to satisfy future demands. Solar energy is frequently used owing to its availability and several benefits. Though more efficient, silicon solar cells are poisonous and expensive. In comparison to other PV cells, the dye‐sensitized solar cells (DSSCs) have several benefits, such as easily accessible materials, low‐cost production processes, simple processing and exceptional diffuse light performance. DSSCs are more reliable alternative to many photovoltaic systems, including hybrid solar cells, inorganic, and organic. DSSCs technology characteristically be influenced by on photosensitizer, electrolyte, and the metal oxide semiconductor. Significant enhancement in cell efficiency has been ranges reach to 12%, using Ru (II) dyes by enhancing substantial besides essential characterization. The dye, that is acting as a source of photoexcited electrons, is the most significant component of a DSSC. This brief review highlights and discusses a summary of the ongoing research made to assist optimization under using N719 dye for DSSC devices.

“…The molecular engineering of metal‐free organic dyes can be achieved through some well‐established synthetic methods (Suzuki, Stille, Sonogashira cross coupling etc.). [ 132 , 133 ] They afford broad and strong absorption in the visible region and have suitable HOMO and LUMO values, resulting in enhanced photovoltaic properties of dyes. Numerous approaches have been adopted to achieve high‐efficiency DSSC devices, such as by testing various novel dyes.…”

Dye‐sensitized solar cells (DSSCs) are a feasible alternative to traditional silicon‐based solar cells because of their low cost, eco‐friendliness, flexibility, and acceptable device efficiency. In recent years, solid‐state DSSCs (ss‐DSSCs) have garnered much interest as they can overcome the leakage and evaporation issues of liquid electrolyte systems. However, the poor morphology of solid electrolytes and their interface with photoanodes can minimize the device performance. The photosensitizer/dye is a critical component of ss‐DSSCs and plays a vital role in the device‘s overall performance. In this review, we summarize recent developments and performance of photosensitizers, including mono‐ and co‐sensitization of ruthenium, porphyrin, and metal‐free organic dyes under 1 sun and ambient/artificial light conditions. We also discuss the various requirements that efficient photosensitizers should satisfy and provide an overview of their historical development over the years.

“…Investigation of the optical properties of push-pull dyes is notably justified by the number of applications requiring push-pull dyes. Thus, push-pull dyes have been extensively used in photopolymerization [ 37 , 38 , 39 , 40 , 41 , 42 , 43 ], non-linear optics [ 4 , 5 , 44 , 45 , 46 , 47 , 48 , 49 ], light-to-energy conversion [ 6 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 ], biological labelling [ 58 , 59 , 60 , 61 , 62 , 63 , 64 ], light-emitting diodes [ 65 , 66 , 67 ] or cell nucleus staining [ 68 , 69 ]. Among electron donors that have only been scarcely used for the design of push-pull dyes, pyrene is one example.…”

Fifteen push-pull dyes comprising the tetracyclic polyaromatic pyrene have been designed and synthesized. The optical properties of the fifteen dyes have been examined in twenty-two solvents of different polarities. Surprisingly, contrarily to what is classically observed for push-pull dyes of D-π-A structures, a negative solvatochromism could be found for numerous dyes. The photoluminescence and thermal properties of the dyes were also examined. Theoretical calculations were carried out to support the experimental results.
