Correlation between Photovoltaic Properties and Thickness of the Hole Transport Layer in Organic-Inorganic hybrid Solar Cells |
| 초록 |
We studied the effect of the hole transport layer (HTL) thickness on photovoltaic properties of organic-inorganic hybrid solar cells. We found that there is an interplay between photovoltaic performance and reproducibility. Thinner HTL (~180 nm) gives higher performing devices, but with lower reproducibility. Because it cannot fully cover the protruding organic-inorganic perovskite crystals, resulting in large leakage current. Therefore, it is necessary that the perovskite layer should be thicker than 150 nm, perfectly covering protruding perovskite crystals preventing direct contact between perovskite and electrode. Our study put emphasis on the importance of fabricating uniform HTL with carefully optimized thickness for obtaining maximum photovoltaic performance. |
