Abstract: 
The influence of the substrate temperature during film growth as well as annealing of films subsequent to preparation was studied by in situ measurements of conduction and photoconduction of molecular blends of phthalocyaninatocopper (PcCu) and buck-minster-fullerene (C-60). The findings are discussed in context of structural and morphological changes observed in scanning electron microscopy (SEM) and UV/Vis transmission measurements. Deposition of bulk heterojunctions (BHJs) at elevated substrate temperature featured improved percolation pathways leading to increased conductivity, photoconductivity, and exciton dissociation yield. At low concentrations of PcCu in C-60 electron trapping by light-induced hole states in PcCu was observed. (c) 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
