Special Issue Information

Dear Colleagues,

In the past few decades, progress has been made in terms of perovskites and their remarkable performance in photovoltaic devices. Perovskite solar cells could become commercial in the near future. Device stability in perovskite solar cells is the most important aspect in order to realize this commercialization. Interface engineering, interface materials and device capsulation are the key solutions that can be used to improve device stability.

The topic of this Special Issue includes all aspects of research related to perovskite solar cells and their applications, including experimental, theoretical, application-oriented, and review articles.

We encourage you to submit manuscripts containing scientific findings within the broad field of perovskite solar research. In particular, the topics of interest include but are not limited to:

  • Strategies to improve device performance and stability;
  • Advanced materials for charge-transporting layers;
  • Novel absorber materials;
  • Flexible perovskite solar cells;
  • Encapsulation methods for improved long-term stability.

To exploit high-performance and stable sensing materials with a room working temperature is pivotal for portable and mobile sensor devices. However, the common sensors based on metal oxide semiconductors usually need a higher working temperature (usually above 300 °C) to achieve a good response toward gas detection. Currently, metal halide perovskites have begun to rise as a promising candidate for gas monitoring at room temperature but suffer phase instability. Herein, we construct 1D/3D PyPbI3/FA0.83Cs0.17PbI3 (denoted by PyPbI3/FACs) bilayer perovskite by post-processing spin-coating Pyrrolidinium hydroiodide (PyI) salt on top of 3D FACs film. Benefitting from the 1D PyPbI3 coating layer, the phase stability of 1D/3D PyPbI3/FACs significantly improves. Simultaneously, the gas sensor based on the 1D/3D PyPbI3/FACs bilayer perovskite presents a superior selectivity and sensitivity toward NO2 detection at room temperature, with a low detection limit of 220 ppb. Exposed to a 50 ± 3% relative humidity (RH) level environment for a consecutive six days, the 1D/3D PyPbI3/FACs perovskite-based sensor toward 10 ppm NO2 can still maintain a rapid response with a slight attenuation. Gas sensors based on hybrid 1D/3D-structured perovskite in this work may provide a new pathway for highly sensitive and stable gas sensors in room working temperature, accelerating its practical application and portable device.
