▎ 摘　　要

A novel concept based on the use of solutions containing already qualified crystalline antimony-doped tin oxide SnO2:Sb (ATO) nanoparticles has been developed. ATO nanoparticles are decorated by reduced graphene oxide (rGO) through a hydrothermal synthesis method. The electrical and optical properties of the graphene oxide films are investigated systematically. The sheet resistance (R square) of the ATO-rGO films decreases with the increase in the rGO content in the precursor solution. The R square can be decreased after the ATO-rGO films annealing in the air for 1 h and can be further decreased by depositing Au on the surface of the films. The optimum property of the ATO-rGO film shows that the R square is 80 Omega/square and the transmittance is about 70 %. The ATO-rGO films are used as the anode of the organic solar cells. The anode film impact on the performance of the devices is studied. Finally, the power conversion efficiency (PCE) of the device based on the poly-(3-hexylthiophene): [6, 6]-phenyl C61-butyric acid methyl ester (PCBM) blended is 1.85 %, and the PCE of the device based on the poly-benzo[1,2-b:4,5-b'] dithiophene thieno[3,4-b] thiophene:PCBM blended is 3.4 %.
