| Popis: | Periodic and random nanostructures as light-trapping management are extremely promising strategies to largely enhance light harvesting and efficiency of solar cell. However, solution-processed films deposited on nanostructured substrates often bring out uncontrollable morphology and lead to deficient interface. In this work, evolved multilayer film morphologies based on nanostructured electrode substrates were investigated in polymer solar cells. It was demonstrated that the different degree of rough front electrodes would significantly influence the morphologies of the following hole transport layer, active layer, and rear electrode layer. The morphological and optical properties of each layer on different rough front electrodes were compared in order to demonstrate the possibly evolved mechanism. A double light-trapping structure with a nano-textured front electrode and micro-textured rear electrode was realized to obtain the high-performance device. |
