The　ternary　oxide　zinc　stannate　(Zn2SnO4)　nanoparticles　are　first　used　as　the　electrode　materials　for　the　quantum　dot　sensitized　solar　cells.　CdS　quantum　dots　are　utilized　to　sensitize　Zn2SnO4　electrode　via　a　chemical　bath　deposition　technique.　The　covering　of　ZnS　layer,　the　kinds　of　conducting　substrates　and　the　thickness　of　film　are　optimized　to　improve　the　cell　performance.　The　optimal　film　thickness　is　found　to　be　6.4　mu　m,　and　the　electrode　prepared　at　sixth　CBD　cycle　exhibits　a　highest　efficiency　of　0.228%　under　the　illumination　of　1　sun　(AM1.5,　100　mW　cm(-2)).　(C)　2011　Elsevier　Ltd.　All　rights　reserved.
