We studied the performance improvement of organic solar cells by optimizing annealing temperature and time Thermal annealing enables crystallization and diffusion of the component in the blend Furthermore, thermal annealing improves the nanoscale morphology which can strongly affect the transport pathways for free charge and also the contact to the electron collecting electrode We could obtain the high efficiency organic solar cell having the J(SC) of 14.1 mA/cm(2), the V-OC of 0 65 V. the fill factor of 06, and the power conversion efficiency of 5 5% by introducing the TiOx interlayer and applying the thermal annealing at 130 degrees C for 30 min and using regioregular poly(3-hexylthiophene, P3HT) and a soluble fullerene derivative (PCBM-71) (C) 2009 Elsevier B V All rights reserved
