Dye- sensitized solar cell （DSC） is considered as the third generation photovoltaic cell. To commercialize DSCs successfully, it is necessary to further improve the efficiency. One of the effective methods is improving the utilization ratio of the solar light and broadening the absorption spectra of the cell. Tandem dye - sensitized solar ceils （TDSC） have attracted much attention due to their novel structure and particular characteristics. In this review, the research background and the recent progress of TD- SC at home and abroad are summarized. The traditional TDSC, N -P type TDSC, hybrid DSC and the tandem cells based on the other type solar cell and DSC are introduced in detail. The recent progress and the existent problems are discussed. Furthermore, the structures, characteristics and efficieneies of every type tandem solar cells are analyzed. At last, the development tendency and promising prospects of TDSC are presented.
