摘要

SrSnO₃ nanoparticles were synthesized and employed for the first time as electrode materials in dye-sensitized solar cells. By optimizing the film thickness, an initial efficiency of 1.02%was obtained. The performance of the dye-sensitized SrSnO₃ solar cells was then improved by using chemical bath deposition (CBD). Electrochemical measurements demonstrated that the CBD treatment not only prohibited interfacial charge recombination but also prolonged the electron lifetimes, resulting in a significantly enhanced efficiency of 1.90%under the illumination of one sun (AM1.5, 100 mW cm^鈭?).
