Boosting Thermal Stability of Perovskite Solar Cells by Introducing New HTL |
| 초록 |
We investigated the effect of new hole-transporting layer (HTL) on thermal stability of perovskite solar cells (PSCs). To fabricate PSCs, we introduced different concentrations of interlayers between perovskite layers and HTLs. Then we measured the power conversion efficiency (PCE) of each device and tested the device stability at 85°C and 85% RH. The champion device with Spiro-OMeTAD HTL had short-circuit current JSC = 22.7 mA/cm2, open-circuit voltage VOC = 1.19 V, fill factor FF = 77.6% and yielded the PCE of 20.9% with high stability. In addition, we fabricated dopant-free PSCs that used an asy-PBTBDT HTL and achieved high efficiency ＞ 19%. This study provides insights that will help guide the development of highly-efficient and thermally-stable PSCs. |
