Abstract |
A new conjugated copolymer bearing donor and acceptor blocks (O-BCP) for the single component active layer was successfully synthesized based on a relatively facile synthesis process which is high yield through one-pot polymerization and purification. The O-BCP contains PBDT-EH2T of p–type units and PNDI-Se of n–type blocks along the polymer chains. All properties of O-BCP were compared with those of blend samples of PBDT-EH2T and PNDI-Se. A single component active layer-PSCs based on as-cast film exhibited a PCE of 2.62%. (Voc = 0.77 V, Jsc = 8.90 mA/cm2, FF = 43.93%). However, through the thermal treatment at 180 oC for 10 min, the devices performance was remarkably improved to show intriguingly high Jsc and FF resulting in >4.57% of PCE. Compared to the O-BCP, the blend film displayed a relatively poor efficiency. (Voc = 0.72 V, Jsc = 6.28 mA/cm2, FF = 43.04%, PCE = 1.94%). |
