ApplicationBTP-4Cl is a high performance, low bandgap, non-fullerene accpetor (NFA). It is the chlorinated derivative of the fused benzothiadiazole-based NFA, Y6. It offer high power conversion efficiency (PCE) when pairing with p-type polymer PM6. A 9 mm2 single junction device of this blend provided a PCE of 16.5% at thickness of ~ 100nm, and provided a PCE of >13% at a thickness of ~300 nm (for the active layer). An impressive PCE of >15% was reached for this blend with a 1 cm2 active layer. In general, Y7 showed improved performances over Y6, mainly due to its highest photoluminescence, lower non-radiative energy loss, and a higher Voc of 0.867 V vs 0.834 V for Y6.
