The four-terminal tandem device relies on FAPbI₃ nanoparticles and a spectral splitting design, combining a 24.4% wide-bandgap top cell and a 21.5% narrow-bandgap bottom cell to reach 30.2% efficiency ...

Silicon solar cells were supposed to be running out of headroom, yet a new device has pushed their performance to 27.81% efficiency and reset expectations for what a single-junction cell can do. That ...

As the U.S. solar PV sector prepares for significant investments into new manufacturing and materials supply facilities in the coming years, the question of technology-leadership for silicon-based ...

Photovoltaic technologies, which convert sunlight directly into electricity, are an important part of the drive towards a more sustainable energy supply. Metal-halide perovskites are an emerging ...

A new study published in Science led by researchers at UNC-Chapel Hill, with collaborators from the Renewable and Sustainable Energy Institute (RASEI), explains why perovskite solar cells—fast-rising ...
