Non-fullerene acceptors (NFAs) with vibrant superiority over fullerene derivatives have proved advantageous as a guest component in a ternary blend signifying improved photon harvesting. However, heterogeneity of NFA-based ternary blend morphology is very complex, and the optimization requires simultaneous considerations of molecular miscibility and electronic properties. We discuss the role of guest NFA for an eased optimization of ternary blend photoactive layer in four different ways. Our four-model prospect of component selection is driven by the well-matched intrinsic miscibility, electronic, and optical characteristics of organic materials. We analyze each model, modulating photoactive layer morphology toward efficient transfer, transport, and collection of charges along with their balanced dissociation and drifting. We believe a model-based selection of NFA and its organization as a guest in a complex ternary blend will serve as a guide for researchers to optimize thin film nanostructures, a route toward efficient larger-area ternary devices.

与富勒烯衍生物相比，充满活力的非富勒烯受体（NFA）已被证明是三元混合物中的客体组分，表明光子的捕集得到了改善。但是，基于NFA的三元共混物形态的异质性非常复杂，优化过程需要同时考虑分子可混溶性和电子特性。我们以四种不同方式讨论了来宾NFA在简化三元混合光敏层优化中的作用。有机材料的良好匹配的固有混溶性，电子和光学特性决定了我们选择组件的四种模式。我们分析每种模型，调节光敏层的形态，以实现电荷的有效转移，运输和收集，以及平衡的解离和漂移。
