Vertically Segregated Photovoltaic Layers :Three-Dimensional Morphology, Charge Transport and Device Performance |
초록 |
Due to the poor carrier mobility and high recombination probability of randomly mixed organic semiconductors in photoactive layers, it is still difficult to obtain maximum efficiency of bulk heterojunction organic solar cells. Photoactive layers having vertical composition gradient can improve photocurrent by enhancing carrier mobility and reducing charge recombination. Here we are going to present photovoltaic layers having vertical composition gradient using organic semiconducting nanowires which have high carrier mobility and light absorption efficiency. Three-dimensional morphology, anisotropic carrier mobilities and device performances of vertically segregated photovoltaic layers will be discussed. |
