摘　　要：Tandem structured dye-sensitized solar cells （DSSCs） can take full advantage of sunlight, effectively broadening the absorption spectrum of the cell, resulting in a higher open circuit voltage or short circuit current than that of the conventional DSSC with single light absorber. The theoretical maximum efficiency is therefore suggested to be over the Schottky-Queisser limit of 33%. Accord- ingly, tandem design of DSSC is thought to be a promising way to break the performance bottleneck of DSSC. Besides, the tandem designs also broaden the application diversity of DSSC technology, which will accelerate its scale-up industrial application. In this paper, we have reviewed the recent progress on photo-electrochemical applications associated with kinds of tandem designs of DSSCs, in general, which are divided into three kinds： ＂n- type DSSC ＋ n-type DSSC,＂ ＂n-type DSSC ＋ p-type DSSC＂ and ＂n-type DSSC ＋other solar conversion devices.＂ The working principles, advantages and chal- lenges of these tandem structured DSSCs have been discussed. Some possible solutions for further studies have been also pointed out together.Tandem structured dye-sensitized solar cells （DSSCs） can take full advantage of sunlight, effectively broadening the absorption spectrum of the cell, resulting in a higher open circuit voltage or short circuit current than that of the conventional DSSC with single light absorber.
