BTP-4Cl

Description

** While supplies last
BTP-4Cl (Y7) is the chlorinated derivative of the fused benzothiadiazole-based NFA (Y6). This low bandgap and strong absorption NFA material has shown tremendous performances when blended with the p-type polymer PM6. The single-junction 9mm2 devices of this blend offer a PCE of 16.5% with a thickness of about 100nm and PCE >13% on 300 nm active layer. The most impressive feature of this blend is the PCE > 15% with a 1 cm2 active layer. Those improved performances over Y6 are mainly due to the highest photoluminescence, which indicates a lower non-radiative energy loss, leading to a higher Voc of 0.867 V vs 0.834 V for Y6.
