Abstract
A dye for dye-sensitized solar cells includes an organometallic complex represented by M(L)X:(Z). In the organometallic complex, M is a Group 8 through Group 10 metallic element, L is a bidentate ligand, X is a co-ligand, and Z is a counter-ion. The ratio of the bidentate ligand (L) to the counter-ion (Z) is about 1.1 to about 1.4. A method of preparing an exemplary dye includes mixing the organometallic complex with tetrabutylammonium thiocyanate and tetrabutylammonium hydroxide to prepare a solution, and purifying the solution at a pH of about 3.8 to about 4.1. A dye-sensitized solar cell includes a first electrode with a light absorbing layer, a second electrode and an electrolyte between the first and second electrodes. The light absorbing layer includes the dye.
