Mark your agenda and register for the upcoming webinar by Australian National University (ANU) scientists Dr. Sieu Pheng Phang and Ms Jiali Wang.
Silicon photovoltaic solar energy stands at the forefront of the global transition towards renewable energy sources. ANU scientists have developed the use of inkjet printing for maskless localized doping of both n-type and p-type polysilicon passivating contacts (minimum feature sizes ≈ 60 µm), offering a pathway to economically produce advanced high-efficiency silicon solar cells. While micro-photoluminescence techniques have enabled us to confirm the effective surface passivation of the printed regions, Dynamic SIMS via the IMS 7f-Auto is uniquely capable of delivering high spatial resolution, depth profiling of the dopant atoms within the silicon solar cell passivating contacts. In particular, the chemical mapping of both boron and phosphorus with SIMS has been instrumental in detecting and quantifying any instances of cross-doping, where dopant atoms migrate or diffuse across unintended regions of the solar cell, which can have detrimental effects on cell performance.
About the presenters
Dr. Sieu Pheng Phang earned his PhD from the Australian National University in 2014. Since then, he has gained a wide expertise in the field of silicon photovoltaics. Among others, he has been engaged in the technology transfer of polysilicon passivating contacts, bridging the gap between laboratory innovation and industrial implementation. He presently focuses on R&D of fully passivating contact silicon solar cells. Dr. Phang's research interests encompass the characterization and simulation of high-efficiency silicon solar cells, the development of perovskite-silicon tandem solar cells, and the integration of high-transparency polysilicon passivating contacts into advanced solar cell technologies.
Ms Jiali Wang is currently a PhD candidate at the Australian National University, where her research focuses on the development and characterization of localized polysilicon passivating contacts achieved through the innovative application of inkjet printing technology. Driven by her enthusiasm for renewable energy, she has been studying photovoltaics materials since her Bachelor’s degree. Jiali has demonstrated n-type and p-type polysilicon passivating contacts using an inkjet material printer, achieving promising passivation quality. Her profound interest in advancing the application of inkjet printing in the realm of high-efficiency solar cells serves as the guiding force behind her current PhD research.
