DRCN5T
DRCN5T is a small molecule donor widely used in organic solar cells (OSCs) with high device performances - achieving power conversion efficiencies (PCE) of over 10%.
Readily available for simple structure synthesis with great potential for further chemical structure tuning, DRCN5T and its derivatives offer great opportunities for the future commercialisation of such OPV devices.

DRCN5T from Ossila was used in the high-impact paper (IF 29.37), Triplet-Charge Annihilation in a Small Molecule Donor: Acceptor Blend as a Major Loss Mechanism in Organic Photovoltaics, J. Marin-Beloqui et al., Adv. Energy Mater., 2100539 (2021); DOI: 10.1002/aenm.202100539.
