Two ruthenium complexes with carboxyl and sulfonyl groups have been synthesized, [Ru-II(L1)(2)(NCS)(2)] Ru(II)bis(4,7-diphenyl-1,10-phenanthroline-disulfonic acid disodium salt)-di(thiocyanate) 110131, [Ru-II(L1)(2)(dcbpy)] Ru-II bis(4,7-dipheny1-1,10-phenanthroline-disulfonic acid disodium salt)(4,4'dicarboxy-2,2'-bipyridyl)  as photosensitizers. UV vis, fluorescence emissjon, AFM and CV measurements are also supplied for ruthenium complexes. Photovoltaic properties of dye sensitized nanocrystalline semiconductor solar cells based on Ruthenium complexes which bear carboxyl and sunfonyl groups have been tested under standard AM 1.5 sunlight. Under the standard global AM 1.5 solar conditions, 1(314 and 1(K313-sensitized solar cells demonstrate short circuit photocurrent densities of 14.92 mA/cm(2) and 11.23 mA/cm(2) and overall conversion efficiencies of 5.09% and 4.02%, respectively.
