University of Queensland researchers have achieved a new global efficiency benchmark for solar cells using eco-friendly perovskite technology. Led by Professor Lianzhou Wang, the team developed a tin halide perovskite (THP) solar cell, achieving a certified record efficiency of 16.65% in converting sunlight to electricity. This surpasses the previous best for THP solar cells by nearly 1%, representing a significant advancement in the field. The reading aligns with many silicon-based solar cells, offering the potential for cheaper and faster production.
Perovskite solar technology presents several benefits, including low-cost potential, defect tolerance, and high efficiency. The THP solar cells utilize more sustainable tin, avoiding the toxic lead commonly found in other perovskite cells, making them safer for residential use. Beyond solar panels, this technology could be applied to devices like lasers, photodetectors, and transistors. The researchers envision THPs powering electric aircraft, highlighting their versatility and potential for future engineering challenges.
