Overview

Solar cells using organic-inorganic lead halide perovskite as light-absorbing materials are considered one of the most important breakthroughs as this discovery will enable cost-effective solar electricity in the future.

Perovskite solar cells (PSCs) have demonstrated energy conversion efficiency of 23.7% achieved with chemical solution processing method, which is comparable to silicon, but at a much lower cost.

Nevertheless, key issues, such as device stability and inconsistent energy conversion efficiency of the device, restrict the commercialisation of PSCs.

Our research group has been focus on addressing these issues through innovative material design and synthesis, device interfacial engineering and deep understanding of the physical mechanism of the device and chemical reactions involved in materials and between materials during the device operation.

Our target is to develop high-performance perovskite solar cells which not only offer high energy conversion efficiency, but also a long lifetime.

Research activities

You will be working with our team to explore new ways to solve scientific and/or practical issue related with perovskite solar cells.

You can contribute to this exciting area by:

  • synthesis and engineering the properties of perovskite nanocrystals and/or thin films
  • development of new electron transport semiconductor such as tin oxide with tailored properties
  • hole transport materials such as nickel oxides with optimized properties
  • characterization of the device under controlled condition to understand its operational mechanism.

Outcomes

The ultimate goal of the project is to make high performance, cost-effective solar cells.

The expected outcomes include but are not limited to:

  • new materials or device design
  • new approach to make the materials enable improved device performance
  • new knowledge of device working mechanism.

The outcomes will be reflected by publications in high quality scientific journals, presentations at prestigious conferences and patents.

Skills and experience

You should have a sound background in chemistry, physics and/or materials science and engineering. We also want you to be interested in semiconductor materials and devices.

While not mandatory, related research experience in the area is preferred.

Scholarships

You may be able to apply for a research scholarship in our annual scholarship round.
