摘要
In this paper, AgBiS2 was prepared on a TiO2 nanorod array via sequential spin-coating 5 mM AgNO3 in DMF, 5 mM Bi(NO3)3 in DMF and 10 mM Na2S in methanol/water (v/v, 95/5) by successive ionic layer absorption and reaction (SILAR) at room temperature. The effect of SILAR cycle times, C11H23COOH surface modification, and spiro-OMeTAD:P3HT application on the photovoltaic performance of the AgBiS2 sensitized solar cell was systematically investigated. The optimal SILAR cycle time for preparing the AgBiS2 sensitized TiO2 nanorod array was 20. The AgBiS2 sensitized solar cell exhibited a power conversion efficiency (PCE) of 0.56% with a 20 cycle time, 0.70% with C11H23COOH surface modification and 0.91% with spiro-OMeTAD:P3HT. AgBiS2 sensitized TiO2 nanorod array was successfully prepared using spin-coating assisted SILAR with AgNO3 in DMF, Bi(NO3)3 in DMF and Na2S in methanol/water at room temperature. The effect of SILAR cycle time, C11H23COOH and spiro-OMeTAD:P3HT application on the photovoltaic performance of the AgBiS2 sensitized solar cell was systematically investigated and the corresponding solar cell achieved the PCE of 0.91%.
