Emerging Perovskite Materials and Novel Applications Beyond Optoelectronics

About this Research Topic

Organic-inorganic lead halide perovskites have revolutionized the research into photovoltaics. The power conversion efficiency has surged beyond 25% in just 10 years after the pioneering work in the area, outperforming all other polycrystalline solar cells and catching up with silicon. Moreover, high performance perovskite solar cells are fabricated by low cost solution processes which are ready to be rolled up for scale-up fabrication. The success of perovskite solar cells intrigues researches of other perovskite optoelectronic devices, such as light emitting diodes, photodetectors, X-ray detectors which are all showing promising progress. The flexibility of the chemistry and structure of perovskite materials presents great opportunities to tune their functionality. Novel applications like ferroelectric, thermoelectric, and photocatalyst are also emerging.

Toxicity of Pb is one of the major obstacles hindering the commercialization of perovskite solar cells. Major efforts have been made to replace Pb with less toxic elements such as Sn, Bi, Sb, Ge, Cu, etc. However, Pb-substituted devices are still far from satisfactory due to either poor stability or low performance. The setbacks can be attributed to the lack of controls on film morphology, crystallinity, and orientation. Intrinsic and extrinsic defects in these emerging perovskite materials also need to be investigated because they directly link to the potential of a new material for optoelectronic application. Strategies of defect formation suppression and defect passivation are also urgently needed.

For applications beyond optoelectronic applications, great opportunities lie in the mostly uncharted territory of transitional metal-based halide and chalcoginide perovskite materials. Looking for perovskite materials with new chemistry and structure to meet the requirements for new applications may lead to the next unprecedented discovery in the field.

This Research Topic aims to investigate emerging perovskite materials for various applications. Subjects of interest include:

• Theory calculation, synthesis, and characterization of emerging perovskite materials, including but not limited to lead-free, transitional metal and chalcoginide perovskite materials.
• Device optimization of perovskite thin-film solar cells using emerging perovskite materials
• Emerging perovskite materials with novel morphologies or structures, particularly with lower dimensions.
• Emerging application of non-oxide perovskite materials, including but not limited to ferroelectric, thermoelectric, magnetic, spintronic, and catalytic applications.


Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
