Isothermal crystallization of P3HT:PCBM blends studied by RHC Vrije Universiteit Brussel
Defining appropriate annealing temperatures and times is vitally important for increasing the efficiency of bulk heterojunction solar cells by favoring the crystallinity of the polymer-fullerene blend components. In order to better understand the annealing process, the isothermal crystallization of poly(3-hexyl thiophene) (P3HT) and [6,6]-phenyl C61-butyric acid methyl ester (PCBM) blend investigated by means of rapid heating cooling calorimetry ...
