6 FAQs about [Nature Communications Chemistry Solar Cells]
Can organic solar cells help us transition to a fossil-free energy supply?
Efficient and environmentally friendly solar cells are required for a transition to a fossil-free energy supply. Researchers at Linköping University have mapped how energy flows in organic solar cells, something that previously had been unknown. The results, which can contribute to more efficient solar cells, are published in Nature Communications.
Are translucent color organic solar cells based on nonfullerene acceptors?
Nature Communications 16, Article number: 597 (2025) Cite this article The artistic and scientific perspectives of the translucent color organic solar cells (OSCs), made with the emerging narrowband nonfullerene acceptors are explored.
Are organic solar cells sustainable?
Solar cells that are cheap and environmentally friendly to manufacture are needed to be successful. In addition, they need to be efficient at absorbing a large proportion of the sun's rays and converting to electrical energy. Organic solar cells based on organic semiconductors are increasingly emerging as a sustainable option.
What is the difference between organic and non-fullerene solar cells?
Footnote: The organic solar cells in the study are of a type where the electron acceptor is made of a material other than fullerene (a form of carbon), which previously was the most common material used. Non-fullerene-based organic cells become more stable and are capable of absorbing a greater proportion of the sun's rays for conversion to energy.
Are non-fullerene-based organic solar cells thermally stable?
Non-fullerene-based organic solar cells generally suffer from poor thermal stability and especially in case of devices with thick active layers. Here, the authors report hexanary blends based on multi-component acceptor mixtures with a device efficiency of 17.6% and thermally stability for 23 days at 130 °C.
Are organic solar cells better than solution-based solar cells?
In comparison, organic solar cells (OSCs) that use solution-based processing technologies are simpler and less expensive to make. The flexibility, color and semi-transparency features also add a decorative and esthetic dimension to the OSCs that can be blended seamlessly into the overall BIPV design.
