| 摘 要： | 开发新型无机空穴传输层材料是钙钛矿电池实现商业应用的重要挑战之一。本文开展了二硫化钨纳米片制备及其钙钛矿太阳能电池空穴传输层应用研究。采用液相超声剥离法成功制备了WS 2纳米片,并将其引入钙钛矿太阳能电池中用作空穴传输层。结果表明,当WS 2纳米片溶液浓度为1 mg/mL时,制备的WS 2纳米片空穴传输层具有较合适的厚度,并且后续在其上生长的钙钛矿活性层成膜质量高、结晶性能好,电池取得6.3%的光电转换效率。结果证实WS 2纳米片可作为新型无机空穴传输层材料用于钙钛矿太阳能电池。

| Abstract: | Developing novel inorganic hole transport layer materials is one of the major challenges for the commercialization application of the perovskite solar cells.The preparation of WS 2 nanosheets and their application for hole transport layer in perovskite solar cells are investigated in this work.WS 2 nanosheets were prepared by liquid phase supersonic exfoliation method.Then by using solution spin-coating method the WS 2 nanosheets thin films were introduced as the hole transport layer(HTL)material in the planar heterojunction perovskite solar cells.The results indicate when the concentration of WS 2 nanosheet solution is 1 mg/mL,the thickness of the WS 2 nanosheet thin films is suitable for the application to the hole transport layer,and the perovskite active layers grown on them have high film quality and good crystallinity.Finally a photoelectric conversion efficiency of 6.3%is obtained.In this study,we demonstrate an effective new use of WS 2 nanosheets HTL in the perovskite solar cells. |
