Synchrotron-based characterization of metal halide perovskites: advances and prospects from Brazilian Synchrotron Light Laboratory sources

Perovskite solar cells (PSCs) have received much attention in the past years due to their fast efficiency rise, low cost and easy preparation. However, several fundamental aspects still need better understanding before PSC is mature for the market. Here, we present a short review of the use of in situ grazing incidence wide-angle X-ray scattering and nano-Fourier-transform infrared spectroscopy (nano-FTIR) techniques for characterizing hybrid organic-inorganic perovskites. These techniques provide relevant information and allow a deeper understanding of the properties of PSC materials helping to improve their properties. Perspectives and challenges for the use of nano-scanning are also discussed. Perovskite solar cells (PSCs) represent a highly potential photovoltaic technology for future electricity generation. To enable a market breakthrough of PSC, improving the efficiency and durability of PSC will be important. To better understand the underlying materials and their properties, more sophisticated characterization tools are required such as synchrotron light sources. Here, we present the latest progress in this field obtained at the Brazilian Synchrotron Light Laboratory including future prospects. Graphical Abstract
