organic solar cells

A novel technical textile integrating 150 organic photovoltaic solar PV devices was demonstrated in a pavilion installation at the Dutch Design Week 2025 in Eindhoven, Netherlands this month.

A research team based in China and the United States has developed electroactive polymer zwitterions to modify zinc oxide interlayers in organic solar cells. Their work was found to passivate defects in organic solar cells, helping to improve device performance and stability.

Scientists from the Korea Institute of Science and Technology (KIST) have used a dielectric additive in organic photovoltaic fabrication to produce uniform films in ambient humidity levels between 10% and 70%. The researchers said the approach improves process stability for organic solar cells.

Researchers in Japan have built a stretchable organic solar cell than can ensure high efficiency levels while preventing crack initiation and propagation. The cell was built with a hole transport layer based on PEDOT:PSS treated with a new additive type.

A team from the Southern University of Science and Technology in China has designed a small molecule donor to act as a third component in ternary organic cells. It helped to achieve a power conversion efficiency of 18.26% when fabricated with a PM6:BTP-eC9 organic solar cell.

A team of researchers in Germany has fabricated a non-fullerene acceptor-based organic photovoltaic cell featuring a bilayer solution-processed hole transporting layer. It recorded a power conversion efficiency of 17.1% and maintained 93% of its initial efficiency after 1,800 hours under continuous solar cell operation at 60 C.

A research team from two Chinese universities claims to have fabricated an organic solar cell with the highest power per weight ratio to date. The device has a thickness of less than 1.5 micrometers.

German organic PV manufacturer Heliatek has announced a new series of lightweight modules. The Heliasol 436-2000-CFE-45-600V panels are IEC 61215 and IEC 61730 certified and have a 20-year lifetime warranty.

An international research team developed an organic solar cell based on a novel non-monotonic intermediated state manipulation strategy. The device reportedly showed non-radiative recombination losses while exhibiting remarkable power conversion efficiency.

Researchers from Japan’s Riken Center for Emergent Matter Science have fabricated an organic solar cell that has achieved waterproofness without reducing flexibility. At 3 micrometers thick, it is thought to be the first cell of its kind to survive a washing machine cycle and retain efficiency after multiple cycles.
