Abstract：In this paper， we used near-infrared absorbing dye SQ2 and visible absorbing hole-transporting material P3HT to make solid-state dye-sensitized cells， and treated the TiO2/SQ2 surface to adjust the photovoltaic performance of the device with lithium salt. The photoelectric performance of the devices was studied by simulating the sun test and monochromatic light quantum conversion efficiency (IPCE) test. Results show that after dealing with the lithium salt， the device exhibited increased short circuit current of (JSC)， fill factor (FF) and conversion efficiency. IPCE of the devices showed that after dealing with lithium salt， the quantum efficiency of devices did not change within the absorption scope of P3HT， while improved significantly within the absorption scope of SQ2. It is concluded that lithium treatment is able to improve the quantum conversion efficiency of photons absorbed by SQ2 instead of P3HT， elevating the efficiency of the solid-state dye-sensitized cells.
