Influence of the preparation conditions of TiO2 electrodes on the performance of solid-state dye-sensitized solar cells with Cul as a hole collector

Solid-state dye-sensitized solar cells (DSSCs) were fabricated in which the thin p-Cul film acts as a hole collector. Influences of the different preparation methods, composition, aging time of the ... pastes and sensitizing time on the performance of the cells were investigated. Different preparation routes for the ... paste do not obviously affect the performance of the cells. The volume of water, acetic acid and 2-propanol contained in the ... pastes and the amount of the ... powder were determined. The efficiency of the cells remains nearly stable when the aging period of the ... pastes is within one week. The favorable dying time is above 2 h. The cells having a favorable performance deliver a mean short-circuit photocurrent of ...10.8 mA ... and mean open-circuit voltage of 0.61 Vat 100 mW ... (1.5 AM). The mean fill factor and the mean efficiency of these cells are ...0.55% and 3.7%, respectively. The short-circuit photocurrent rapidly decays after 3 h, and at the same time, the open-circuit voltage slowly decreases when the time increases, and then remains nearly stable after 24 h.
