摘要

采用一步涂层法制备TiO₂/PbS异质结且带有不同浓度PbS量子点光吸收层的太阳电池器件。测试结果表明,用浓度为200 mg/mL的PbS量子点制备的太阳电池在AM1.5模拟光照下获得的能量转换效率（PCE）为9.08%,其开路电压（V_OC）为0.570 V、短路电流（J_SC）为29.6 mA/cm²、填充因子（FF）为0.539。研究证实了一步法的可行性与可靠性。与传统的层层旋涂法相比,一步涂层法具有操作过程简单、材料消耗少、制备薄膜质量好等优点,可用于大批量制备高效率量子点太阳电池。

Abstract

To fabricate high efficiency quantum dot solar cells, the absorbing p-type PbS quantum dots was prepared on n-type TiO₂ by simplified single-step spin coating method. In order to confirm the effectiveness of the single-step method and obtain high efficiency devices, QDSCs with two different concentrations of PbS QDs are prepared and their performance is investigated. It is demonstrated that the device with lower QD loading achieved higher power conversion efficiency （PCE） of 9.08%, with open-circuit voltage （V_OC） of 0.570 V, short-circuit current density （J_SC） of 29.6 mA/cm², fill factor （FF） of 0.539, under simulated AM1.5 solar illuminations. The experiment results verify feasibility and reliability of the single-step method. Compared with traditional layer-by-layer （LBL） method, the single-step method demonstates merits of simpler process, less material consumption, and higher surface quality. Consequently, it is potential to apply single-step for quantum dot solar cell mass production.
