The performance of silicon solar cells is limited by the inefficient utilisation of high-energy sunlight. Photons in the ultraviolet and blue region often lose excess energy as heat rather than contributing to useful electrical power. In addition, ultraviolet radiation can gradually degrade modern high-efficiency silicon solar cells, reducing their long-term stability. Addressing these challenges is an important direction in the development of next-generation photovoltaic technologies.
This project aims to explore luminescent down-conversion coatings that can be applied to the surface of silicon solar cells. These materials can convert high-energy photons into wavelengths that are more efficiently absorbed by silicon, potentially improving photocurrent generation while also reducing the impact of harmful UV radiation.
The student will work closely with a senior researcher and join a small research group comprising postgraduate students and early-career researchers. The project will involve literature review, discussion of research ideas within the group, and participation in basic experimental or data analysis activities. Through this experience, the student will gain insight into how advanced materials can contribute to improving the efficiency and stability of future solar energy technologies.

The project will be conducted in a materials science and photovoltaic research laboratory equipped for nanomaterials synthesis and optical characterization.
The research environment will include:
- A wet-chemistry laboratory for nanocrystal synthesis
- Optical spectroscopy facilities for UV-Vis and photoluminescence measurements
- Electrical characterization for performance evaluation of down-conversion layer incorporated silicon solar cells
- Students will work under the supervision of a research mentor (PhD student or postdoctoral researcher) and gain experience in laboratory safety, experimental design, and scientific data interpretation.
Regular meetings and discussions will support the students progress and introduce them to the broader field of nanomaterials for renewable energy technologies.
By the end of the project, the student is expected to:
- Develop foundational skills including literature review, experimental planning, data analysis and scientific reporting
- Gain laboratory knowledge, basic nanomaterials synthesis techniques and optical-electrical characterization methods
- Understand key concepts in PV materials
- Produce a short research report or presentation, summarizing research background, methodology, key findings and future research directions
