Using the self-assembly properties of liquid crystal materials
a cholesteric phase liquid crystal 3-Hydroxy-5-cholestene 3-oleate (CLC) is doped into the active layer of P3HT:PC61BM of organic polymer solar cells to manufacture photovoltaic devices with different doping proportion.The result shows that the efficiency of the device is highest when the CLC doping ratio is 0.3%.In conclusion
the self-assembly properties of CLC can promote the active layer molecules to be arranged more orderly during its crystallization proceeding.The effective crystallization results in a reduction of the molecular clusters and the layer defects in the active layer; and therefore it is useful to form a well transport channel for carrier transport. With the proper doping ratio
a high shunt resistor and fill factor of the device are obtained.The performance of the device is improved.
