Temperature-dependent barrier height inhomogeneities in PTB7:PC71BM-based organic solar cells

We report on the temperature-dependent Schottky barrier in organic solar cells based on PTB7:PC71BM. The ideality factor is found to increase with temperature decreasing, which is explained by a model in which the solar cell is taken as Schottky barrier diode. Accordingly, the dark current in the de...
