ACAP researchers at ANU have tackled degradation in perovskite silicon tandem cells, by deliberately running tandem cells in a slightly mismatched mode, where the silicon layer limits the overall current – and dramatically suppresses the problematic voltage fluctuations in the perovskite layer.

As part of ACAP's expansion of outdoor PV testing facilties, CSIRO's PV Outdoor Test Facility has had a substantial upgrade and is now accessible to all ACAP researchers.

Dr Chris Fell outlined key challenges and opportunities in solar PV manufacturing and sustainability, and ACAP's highlights and progress at the ACAP Conference 2025.
