采用化学浴沉积工艺成功制备了涂有 CdS 量子点 (QD) 的 ZnO 纳米线 (NW) 阵列。扫描电子显微镜 (SEM)、透射电子显微镜 (TEM) 和 X 射线衍射 (XRD) 已用于表征样品。我们通过表面光电压（SPV）和瞬态光电压（TPV）测量研究了可见光区域光生电荷的分离和重组过程。通过控制 CdS QD 的附着量，我们发现表面光电压特性发生显着变化。以液体电解质作为空穴传输介质，量子点敏化纳米线太阳能电池（QDSSC）在100 mW cm−2的光强照射下表现出0.8至2.6 mA cm−2的短路电流和0.35–0.44 V的开路电压。还讨论了 QDSSC 的性能与其光电压特性之间的关系。
ZnO nanowire (NWs) arrays coated with CdS quantum dots (QDs) were successfully fabricated with a chemical bath deposition process. Scanning electron microscopy (SEM), transmission electron microscopy (TEM) and x-ray diffraction (XRD) have been utilized to characterize the samples. We have studied the processes of separation and recombination of the photo-generated charges in the visible region by surface photovoltage (SPV) and transient photovoltage (TPV) measurements. By controlling the amount of attached CdS QDs we found that the surface photovoltage characteristics change significantly. With a liquid electrolyte as the hole transport medium, the quantum dot sensitized nanowire solar cells (QDSSCs) exhibited short-circuit currents ranging from 0.8 to 2.6 mA cm−2 and open-circuit voltages of 0.35–0.44 V when illuminated with light intensity 100 mW cm−2. The relation between the performance of QDSSCs and their photovoltage characterization was also discussed.
