Perovskite solar cells have attained tremendous interest due to their skyrocketing power conversion efficiency to 25.2% recently, becoming comparable to commercial silicon photovoltaics. However, there are still stability issues to be overcome for commercializing perovskite solar cells. Nanocrystal engineering can be one of the most effective strategies to improve not only photovoltaic performance but also the stability of perovskite devices. In particular, inorganic perovskite nanocrystals (NCs) have shown good potential as an emerging semiconducting building block owing to their excellent optoelectronic properties. In this work, we report a facile method for production of multi-dimensional perovskite nanomaterials. We employ the structure-tailored nanomaterials in optoelectronic devices such as solar cells and photodetectors, which facilitates the device performance and eventually, device operational stability. We believe our work would provide a widely utilizable method and an enormous promise for perovskite-based optoelectronic applications. |
