Revolutionizing Solar Energy: Key to Efficient Organic Cells

• Professor Philip C.Y. Chow and team revolutionize solar energy with Y6 molecule, boosting efficiency and stability in organic photovoltaics. A game-changer for sustainable energy solutions.

A team of researchers led by Professor Philip C.Y. Chow from the University of Hong Kong has made a breakthrough in organic photovoltaics, paving the way for more sustainable solar energy solutions. Their research, published in Nature Communications, focused on a new electron-accepting molecule called Y6, which showed promise in creating efficient and stable solar cells. By controlling the aggregation of polymerized Y6 acceptors, the team improved electricity generation and device stability.

The researchers found that Y6-PAs have higher miscibility with donor polymers, forming a nanoscale percolation network that enhances charge generation efficiency and improves device stability over time. This discovery could lead to the development of efficient and stable polymer-based solar panels for various applications, including buildings, vehicles, and electronic products. Collaborating with teams from North Carolina State University, the Chinese Academy of Science, and the City University of Hong Kong, the interdisciplinary research integrated expertise in optical spectroscopy, quantum chemical modeling, X-ray scattering, and solar cell manufacturing.
