Scalable Approaches to Address Thermomechanical and Chemical Instabilities in Metal Halide Perovskites
We will discuss our group’s recent efforts to address the thermomechanical and chemical instabilities of metal halide perovskites through multiple approaches. These approaches cover several length scales and aim to provide better understanding of behavior in all stages of processing—i.e., precursor behavior in inks, growth behavior of films during printing, and resulting optoelectronic properties and robustness of perovskite films and devices. We will highlight our efforts toward scalable printing of high-quality perovskite using the method recently invented by our group restricted area printing by ink drawing (RAPID). Additionally, we will discuss how molecular additives in precursor inks can influence the stability of the inks and resultant films. Finally, we will also describe our recent progress in addressing the poor mechanical toughness of perovskite using multifunctional nanofiber reinforcements. Together, all of these concepts are complimentary and compatible with scalable printing of perovskites and a necessary step towards developing a viable technology with long operational lifetimes.
