Polymer solar cells have recently attracted great attention due to their intrinsic advantages including low-cost manufacturing and a variety of features such as flexibility, light-weight, ultra-thin shape, etc. The land-marking breakthroughs in polymer:fullerene solar cells can be attributed to the nanomorphology control of bulk heterojunction layers by employing various techniques. In this work, we investigated the time-dependent nanostructure changes of polythiophene:fullerene blend films at various temperatures in order to understand the correlation between annealing time and temperature. The trend of time-dependent nanostructure change in the polythiophene:fullerene blend films was correlated with device performances with the same blend films. |
