Development of High-Efficiency Solar Cells Using Novel Laser Processes
Solar photovoltaics (PV) have emerged as a transformative technology in the clean energy transition, playing a pivotal role in combating climate change. The rapid advancements in solar cell efficiency over the past decades have made PV the most cost-effective form of new electricity generation across many regions globally. As a result, solar PV is projected to dominate global installed capacity, surpassing all other energy sources by the end of the current decade. This ongoing revolution in PV technology not only promises a substantial reduction in greenhouse gas emissions but also presents new economic opportunities, such as green hydrogen production, through even more efficient and affordable solar electricity.
The core focus of this PhD project is to contribute to the development of the next generation of high-efficiency solar cells by leveraging novel laser processes to fabricate interdigitated back contact solar cells. These cutting-edge solar cell designs have the potential to achieve significantly higher efficiency while maintaining a cost-effective production process. Your research will involve exploring and optimizing various deposition techniques to prepare dopant sources used in subsequent laser doping. Advanced characterization techniques will be utilized to investigate the electrical properties of these cells, ensuring their optimal performance.
As a part of the Silicon Solar Cells & Modules group at ANU, you will be part of a dynamic and collaborative team of over 25 researchers, working at the forefront of photovoltaic research. Your direct mentorship will be provided by leading experts in the field, offering valuable guidance and support throughout the project. The research activities within the group encompass a wide range of solar electricity technologies, from solar forecasting to fabricating high-efficiency photovoltaic cells and integrating renewables with storage capacity into the grid. Notably, the group excels in silicon photovoltaic device fabrication and characterization, developing advanced materials and cutting-edge technology for high-efficiency silicon solar cells and modules. Furthermore, their strong partnerships with industry and academic experts worldwide have led to the successful commercialization of numerous research outcomes.
The research will be conducted in state-of-the-art laboratories, well-equipped with advanced fabrication and characterization facilities. These cutting-edge facilities include various semiconductor fabrication processes like diffusion, ion implantation, chemical vapor deposition, and laser-based cutting and doping, among others. Additionally, you will have access to a brand new, state-of-the-art ALD system within the newly installed materials deposition cluster. The characterization facilities encompass state-of-the-art optical, electrical, and microscopy tools, enabling techniques such as luminescence spectroscopy and imaging, spectroscopic ellipsometry, Raman spectroscopy, photoemission yield spectroscopy, and solar simulators. Moreover, access to other materials characterization techniques, such as Fourier transform infrared spectroscopy, X-ray diffraction, atomic force microscopy, and electron microscopy, further enriches the resources available for your research.
Undertaking this PhD project will provide an excellent training environment, equipping you with the necessary skills and expertise to pursue a rewarding career in photovoltaics, semiconductors, or materials research in either industry or academia. Through your contributions to the advancement of high-efficiency solar cells, you will play an instrumental role in driving the clean energy transition and combating climate change on a global scale.
