N719 dye as a sensitizer for dye‐sensitized solar cells (DSSCs): A review of its functions and certain rudimentary principles

Abstract

AbstractNew 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.
