Abstract Sb2S3 is a promising sensitizer material for solar cell devices. Growth and morphological characteristics of Sb2S3 nanoparticles made by chemical bath deposition on anatase TiO2 with various morphological attributes including mesoporous P25 nanoparticles, microsphere and its composite, anodized nanotubes, and nanorods are shown to widely differ. Sb2S3 coated on P25 photoanode for different time duration (45 min to 4 h) show that the deposition for 2 h is sufficient to obtain uniform coating with good crystallinity. Sb2S3 growth on TiO2 nanotube, nanorod and microspheres lead to conformal coverage, whereas, it hardly grows on glass/FTO. Photoconversion ability is studied using photoconductivity and photovoltaic measurements. Optimally sensitized Sb2S3 solar cells fabricated using I−/I3− liquid electrolyte exhibit photoconversion efficiency up to 0.35 % for cell area of 0.25 cm2. High photoconductivity found in Sb2S3 sensitized TiO2 microsphere-composite and nanorod compared to the P25-TiO2 photoanode is attributed to good connectivity between particles and effective electron transport.

Sb2S3 半导体薄膜在不同形貌 TiO2 纳米结构上的生长

摘要 Sb2S3 是一种很有前途的太阳能电池器件敏化材料。通过化学浴沉积在锐钛矿 TiO2 上制备的 Sb2S3 纳米粒子的生长和形态特征具有各种形态属性，包括介孔 P25 纳米粒子、微球及其复合材料、阳极氧化纳米管和纳米棒。Sb2S3 涂覆在 P25 光阳极上不同的持续时间（45 分钟到 4 小时）表明，2 小时的沉积足以获得具有良好结晶度的均匀涂层。Sb2S3 在 TiO2 纳米管、纳米棒和微球上的生长导致保形覆盖，而在玻璃/FTO 上几乎不生长。使用光电导率和光伏测量来研究光转换能力。使用 I-/I3- 液体电解质制造的最佳敏化 Sb2S3 太阳能电池在电池面积为 0.25 cm2 时表现出高达 0.35% 的光转换效率。与 P25-TiO2 光阳极相比，在 Sb2S3 敏化的 TiO2 微球复合材料和纳米棒中发现的高光电导性归因于粒子之间的良好连接性和有效的电子传输。
