BTP-4Cl-12


Product Code M2327A1
Price £200.00 ex. VAT

BTP-4Cl-12, also known as Y7-BO or BO-4Cl, belongs to the highly efficient non-fullerene acceptor Y6 family. The only different between BTP-4Cl-12 and Y7 is that BTP-4Cl-12 has  larger butyloctyl alkyl chains that are attached to the pyrrole rings while Y7 has ethylhexyl alkyl chains at the clove of the U-shaped structure. Also, BTP-4Cl-12 has greater solubility so it has great advantage for solution processability and mass device production with environmentally benign solvents as active layer materials for organic polymer solar cells.

By the method of delayed processing using non-halogenated solvent toluene, optimized nano-fibril like morphology of PM6:BTP-4Cl-12 can be achieved with more efficient charge separation and transport and outstanding device performance efficiency of 17.33% in PCE.
