Facile interfacial engineering of mesoporous TiO2 for flexible perovskite solar cells |
| 초록 |
The mesoporous TiO2 nanoparticle-based scaffold structure is the best electron transport layer (ETL) for perovskite solar cells (PSCs) and is still used in most of PSCs having optimal photovoltaic characteristics. However, the high sintering temperature of TiO2 nanoparticles, required to remove binders from the TiO2 paste, limits the PSC application to flexible electronics. In this study, a simple interface modification process involving ethanol rinsing is developed to enhance the photovoltaic characteristics of low-temperature processed PSCs. This easy and fast technique could allow remarkable performance by significantly increasing the fill factor and current density, leading to a power conversion efficiency more than four times that of untreated solar cells. |
