Amit Kessel and a collaborative team from Monash and UNSW have demonstrated semi-opaque perovskite solar cells (SO-PSCs) that combine high efficiency, excellent colour-neutrality, and the clarity required for real building windows. In 2025, researchers at Monash University and UNSW , supported by the Australian Centre for Advanced Photovoltaics (ACAP), achieved a major step forward in the development of next-generation photovoltaic windows.
