This paper reports the application of the \(R{u^{2 + }}, C{u^ + }, and F{e^{2 + }}\) complexes in form of RuL2(SCN)2, CuL2(SCN)2 for dye-sensitized solar cell (DSSC) development. The calculation results, given by quantum chemistry, demonstrated that the complex containing copper is more suitable than the one containing iron. The modification of Cu(I) complex by using various numbers of ligands enhanced photon absorption capacity as well as the absorption range. |
