Abstract
Expression of concern for ‘Low energy loss (0.42 eV) and efficiency over 15% enabled by non-fullerene acceptors containing N-bis(trifluoromethyl)phenylbenzotriazole as the core in binary solar cells’ by María Privado et al., J. Mater. Chem. C, 2022, 10, 13174–13182, https://doi.org/10.1039/D2TC02289C.
Journal of Materials Chemistry C is publishing this expression of concern in order to alert readers about concerns with the TEM images of P1:TOCR1 and P1:TOCR2 films in Fig. 6. An expression of concern will continue to be associated with the article until we receive conclusive evidence regarding the reliability of the reported data.
