【Abstract】 The fundamental structure,working principle and characteristics of dye sensitized TiO₂ nanocrystalline photoelectrochemical cell（NPC） are introduced.Compared with the conventional solar cells based on silicon,sensitized NPC is a low-cost cell.It is similar to the photoelectrochemical cell（PEC） and its performance is more excellent than PEC due to the key technology different from PEC.The reasons and influence factors of high overall photo-electric conversion efficiency are discussed.The selection of organic or inorganic sensitizer for NPC, and the state-of-arts of overall photo-electric conversion efficiency,open-circuit voltage and short-circuit current are also reviewed.更多还原
