Transmitting solar energy generated in space back to Earth has long been the subject of science fiction, first appearing in Isaac Asimov’s 1941 short story, Reason, where solar energy is converted to microwaves by a space station, and beamed back to nearby planets.

As countries around the world strive to curb climate change, it becomes increasingly clear that radical innovative energy solutions are needed if we are to stand any chance of achieving net zero emissions. A team of engineers at the University of Queensland may have provided one such solution in the field of quantum dot solar cell technology, achieving a near 25% improvement, and a world record, for the conversion of solar energy into electricity using quantum dots. Inventor, and Australian Research Council laureate, Lianzhou Wang, explains that the improvement “is effectively the difference between quantum dot solar cell technology being an exciting prospect and being commercially viable”.
A new study led by the Australian National University could lead to cheaper and more efficient solar technology. According to the study, the current photovoltaic (PV) cell market is dominated by silicon based technology, which is nearing its theoretical efficiency limit.
