Very recently, organic–inorganic halide perovskites attracted tremendous attention because of their unique optoelectronic properties (e.g., large absorption, long diffusion length and high mobility). In addition, organic–inorganic halide perovskites can be prepared by versatile fabrication methods, such as spin-coating, spray, co-evaporation, chemical vapor deposition, etc. Perovskite solar cells (PSCs) thus hold great potential for utilizing solar energy at low cost. With only six years of intensive research, power conversion efficiencies of PSCs have rapidly increased to over 22%, i.e., a level that is nearly on par with traditional silicon solar cells. To further improve the performance of PSCs and lower the fabrication cost, further efforts on the fundamental aspects (such as understanding the structural and opto-electronic properties, role of defects, energy level alignment at interfaces, recombination properties, hysteresis phenomenon, instability, etc) and the reproducible scale-up fabrication methods are urgently needed.

The most suitable metal cation for highly efficient PSCs is lead (Pb2+), which gives rise to environmental problem if it is not disposed or recycled properly after usage. Thus, effort on exploring non-lead perovskites is also very important for the development of perovskite-based solar cells. The extensive researches mentioned above will give insight to understand the nature of organic–inorganic halide perovskites and speed up the commercialization of PSCs.

In this Research Topic, we welcome submissions regarding

• new preparation methods of perovskite thin film/single crystal with high reproducibility
• perovskite/device structure optimization
• flexible/semi-transparent perovskites
• energetic aspects at interfaces
• charge transport/injection properties
• defect properties
• photo-physics such as emission and recombination,
• unusual phenomena such as hysteresis and ion migration
• theoretical calculation/simulation
• scale-up production methods for industrialization

We also welcome contributions regarding environment assessment of PSCs, exploration of lead-free perovskites, degradation issues, methods for expending life span of PSCs, etc.
The format of submissions can be original research articles and reviews.
