摘要
采用两步水热法在导电玻璃(FTO)上制备TiO2分枝纳米棒(B-NR)阵列。利用低温化学浴沉积法(CBD)在TiO2分枝纳米棒阵列(B-NRA)基底上沉积Sb2S3纳米粒子(NPs)。接着分别旋涂P3HT和Spiro-OMeTAD组装成TiO2(B-NRA)/Sb2S3/P3HT/Spiro-OMeTAD为光活性层的杂化太阳电池。通过对杂化太阳电池的光电性能测试,结果表明,TiO2分枝纳米棒阵列具有高的吸光强度,较大的比表面积和多级电荷传输通道,由TiO2(B-NRA)/Sb2S3/P3HT/Spiro-OMeTAD复合膜结构组装的杂化太阳电池的能量转换效率(PCE)是4.67%。
Branched TiO2 nanorod(B-NR)array were prepared on conducting glass(FTO)by two-step hydrothermal method.Sb2S3 nanoparticles(NPs)were deposited on branched TiO2 nanorod array(B-NRA)substrates by low temperature chemical bath deposition(CBD).The P3 HT and Spiro-OMeTAD were spin-coated on the TiO2/Sb2S3 composite membrane structure successively to form hybrid solar cell with TiO2(B-NRA)/Sb2S3/P3 HT/Spiro-OMeTAD as photoactive layer.Through the photoelectric performance test of hybrid solar cell,the results show that branched TiO2 nanorod array had high light absorption intensity,large specific surface area and multi-stage charge transport channels.The photoelectric conversion efficiency(PCE)of the hybrid solar cell assembled with the TiO2(B-NRA)/Sb2S3/P3 HT/Spiro-OMeTAD composite membrane structure was 4.67%.
