lead-free perovskites

Scientists in China examined some of the key achievements in the development of perovskite solar cells in 2020 and 2021. The group finds that translating laboratory achievements onto larger, manufacturable devices, is the biggest challenge, and sees continuing collaboration between the industry and academic researchers as the key to overcoming this challenge.

As a focus of research at leading institutes the world over, new developments in the perovskite field come thick and fast almost every week. From x-ray observations on a nanoscale to financing and plans for mass production, pv magazine is bringing together some of the most exciting developments of recent weeks.

Scientists at the Massachusetts Institute of Technology have developed an accelerated process for screening new perovskite compounds as they search for those with the potential to be used in high efficiency solar cells. According to MIT, the process speeds up the synthesis and analysis of new compounds by a factor of ten and has already highlighted two sets of materials worthy of further study.

Researchers at the University of California, San Diego – with the help of the university’s Comet supercomputer – modelled thousands of halide compounds to come up with a shortlist of 13 materials that could be candidates for the efficient solar cell materials of the future.

Scientists at Oxford University say two lead-free perovskites investigated for their potential to raise the efficiency of solar modules – when used in tandem with high efficiency silicon cells – may also offer a leap forward in solar storage technology. In a paper published in Applied Physics Letters, Feliciano Giustino and George Volonakis, suggest halide […]
