BLEND OF P3HT AND Spiro-OMeTAD AS PHOTOACTIVE LAYER AND HOLE TRANSPORT LAYER IN HYBRID SOLAR CELL

摘要: 将P3HT与Spiro-OMeTAD共混后的混合物作为光活性层和空穴传输层,将其旋涂在由不同锑源和硫源比例（Sb/S）制备的Sb₂S₃纳米粒子敏化的TiO₂纳米棒(TiO₂（NR）/Sb₂S₃)复合膜上,制备成杂化太阳电池。对所得杂化太阳电池的微观结构和光电转换特性进行研究,在锑源和硫源比例（Sb/S）为1/1,P3HT与Spiro-OMeTAD共混物比例为15 mg∶1 mL时得到的结构为FTO/TiO₂（NR）/Sb₂S₃（1∶1）/P3HT:Spiro-OMeTAD（15 mg∶1 mL）/Ag的杂化太阳电池的能量转换效率达到4.57%

Abstract: A blend P3HT and Spiro-OMeTAD is used as photoactive layer and hole-transport material which is coated on TiO₂nanorod/Sb₂S₃nanoparticles composite film to prepare the hybrid solar cell.In the composite film,Sb₂S₃nanoparticles are prepared with different ratios of antimony source and sulfide source（Sb/S）.The microstructure and photovoltaic performance of the hybrid solar cell are studied.The power conversion efficiency of the hybrid solar cell is 4.57%when FTO/TiO2/Sb₂S₃is 1/1,and P3HT/Spiro-OMeTAD is15 mg/1 mL,with the structure of FTO/TiO₂（NR）/Sb₂S₃（1/1）/P3HT:Spiro-OMeTAD（15 mg∶1 mL）/Ag.
