摘　　要：In dye-sensitized solar cells （DSSCs）, the TiO2 underlayer can block the electron recombination at the FTO （fluorine doped SnO2） glass/electrolyte interface. This underlayer was traditionally prepared by spray-pyrolysis or spin coating. In this study, we develop an alternative method based on screen-printing. The quality of the screen-printed underlayers is characterized by SEM, XPS and the photoelectrochemistry measurements. The prepared underlayers are smooth and effective. The screen-printing technique is cheap and easy to handle and can produce films with different patterns. These advantages will facilitate applications of the screen-printed underlayer.In dye-sensitized solar cells （DSSCs）, the TiO2 underlayer can block the electron recombination at the FTO （fluorine doped SnO2） glass/electrolyte interface.
