ABSTRACT
In the context of environmental concerns, solar energy systems offer more advantages in that they are clean and emit no pollutants into the atmosphere. An ever-increasing interest has been directed toward photoelectrochemical processes as applied for solar energy to electric energy conversion. Dye-sensitized solar cells (DSSCs) are assured as next-generation solar cells due to their potentially high conversion efficiency. However, the liquid electrolyte in DSSCs creates low stability, due to easy evaporation of solvent and sublimation of iodine. The organic compound carbazole dendrimer based BODIPY was used as a photosensitizer in dye-sensitized solar cells with a good efficiency of 2.7%. In the photoelectrochemical field, particularly dye-sensitized solar cells, the organic molecule plays a vital role. In dye-sensitized solar cells, the dendrimer-based BODIPY molecule reports good solar to electric energy conversion efficiency.
