A new review article on Low‐Dimensional‐Networked Perovskites

Stable, low‐dimensional‐network perovskite materials with tailored molecular dimensionality are promising materials for optoelectronic devices including solar cells, light emitting diodes, luminescent solar concentrators, and photodetectors with enhanced performance and stability. This review summarizes the research progress and challenges in this area, providing insights into the […]

The effect of ethylene-amine ligands enhancing performance and stability of perovskite solar cells

The effect of ethylene-amine ligands enhancing performance and stability of perovskite solar cells

We develop an approach that combines molecular dimensionality control and interfacial passivation of perovskite layers using a novel post-device treatment (PDT) with the vapour of ethylene-amine salts of different carbon chain lengths to improve both efficiency and stability of the PSCs. The effect of a […]

1D Pyrrolidinium Lead Iodide for Efficient and Stable Perovskite Solar Cells

1D Pyrrolidinium Lead Iodide for Efficient and Stable Perovskite Solar Cells

A method to form 1D pyrrolidinium lead iodide (PyPbI3) in situ atop photoactive 3D methylammonium lead iodide (MAPbI3) using pyrrolidine posttreatment is reported. As compared with 3D MAPbI3, 1D PyPbI3 has a wider bandgap and is more environmentally stable, and it serves as a tunneling contact to mitigate charge carrier recombination and as a robust barrier against environmental degradation when incorporated into organometal halide solar cells.

A new review article on Energy & Environmental Science journal by Prof. Hongxia Wang

The article “Kinetic and material properties of interfaces governing slow response and long timescale phenomena in perovskite solar cells” reviews the most recent advancement on understanding the interfaces in PSCs, in particular the interfaces of perovskite/electron transport layer (ETL) and perovskite /hole transport layer. Furthermore, It provides a guidance in the immense complexity of dynamic behaviours of the PSCs, particularly concerning the slowest time scale measurement that have a maximum impact in the actual operation of the solar cell and address the separation of phenomena such as ion migration, interfacial charge accumulation, and surface electrochemical reactions.

Professor Hongxia Wang is granted the ARC Discovery Projects Funding 2019, the funding for world-leading research.

The Approved Proposal:

Green synthesis of organometal perovskite solar cells. This project aims to understand the mechanism that governs the formation and crystallisation process of organic-inorganic lead halide perovskite films from non-toxic, environmentally friendly, protic ionic liquids. The project will develop new ionic liquid solvent systems that deliver appropriate morphology, and electrical and optical properties to fabricate high performance perovskite solar cells using environmentally friendly, low-toxicity processes. Successful achievement of the outcomes will enable environmentally-friendly, industrial scale processing of perovskite materials, placing Australia at the forefront of organometallic perovskite materials processing with applications in renewable energy and other electro-optical applications.
