A concept of fabrication of well-organized conductive pathways in CP/NP blends in photovoltaic devices. It is assumed that to succeed in this task, one can use the property of AB diblock copolymers that, depending on the chemical structure of A and B blocks and the ratio between their lengths, these copolymers undergo microphase separation in bulk to form thermodynamically stable domains of cubic symmetry with 3D periodicity. Using a mesoscale simulation technique, we demonstrated that the morphology of the photoactive layer of photovoltaic devices can be controlled by selecting the surface NP modifier (responsible for the compatibility of NPs with the polymeric matrix), the chemical structure of the blocks of a conjugated copolymer, and their length.

控制光伏元件中聚合物光敏层的形态：介观模拟

在光伏器件中的 CP/NP 混合物中制造组织良好的导电通路的概念。假设要成功完成这项任务，可以利用 AB 双嵌段共聚物的特性，根据 A 和 B 嵌段的化学结构以及它们的长度比，这些共聚物会在体内进行微相分离以形成热力学稳定的区域具有 3D 周期性的三次对称。使用中尺度模拟技术，我们证明可以通过选择表面 NP 改性剂（负责 NP 与聚合物基体的相容性）、共轭共聚物嵌段的化学结构来控制光伏器件的光敏层的形态，以及它们的长度。
