Researchers at the University of Queensland have achieved a new efficiency record for tin halide perovskite (THP) solar cells, reaching a certified conversion efficiency of 16.65%. This advancement surpasses the previous record by nearly one percentage point, marking a significant milestone in the development of cost-effective and environmentally friendly solar technologies.
THP solar cells utilize tin instead of lead, addressing environmental concerns associated with traditional perovskite cells. The use of tin not only reduces toxicity but also offers the potential for faster and more economical production processes. Professor Lianzhou Wang, who led the research team, emphasized the importance of this achievement in advancing sustainable energy solutions.

Context & Background
Perovskite solar cells have been a focal point in photovoltaic research due to their high efficiency and low production costs. Traditional perovskite cells often incorporate lead, raising environmental and health concerns. The development of tin-based perovskite cells offers a promising alternative, mitigating these issues while maintaining competitive performance levels.
In recent years, Australian institutions have been at the forefront of solar energy research. For instance, in 2021, an Australian start-up achieved a world record by creating the most efficient commercial-sized solar cell using copper instead of silver, enhancing both efficiency and cost-effectiveness. Additionally, in early 2025, the University of New South Wales set a world record with a 13.2% efficiency for kesterite solar cells, highlighting the nation’s commitment to advancing solar technologies.
