The control of the active layer morphology is highly important to the photon to electron conversion in organic and hybrid solar cells with multi length scales. The direct visualization of three-dimensional bulk heterojunction morphologies has been challenging due to the complex molecular organization. In this presentation, we spatially resolve the morphology of hybrid thin-film based on the crystalline nanowires consisting of poly(3-hexylthiophene)-based polymers as the donor and quantum dots (QDs) as the acceptor via TEM tomography (TEMT). The hybrid nanowires are formed by conventional solvent mixing method, and then cast into thin-film for active layer. Interestingly, the crystallization of conjugated polymers are elucidated by the QDs nano-location within the hybrid nanowires in which the QDs are coaxial located along to the longitudinal and vertical nanowire axis. Therefore, the morphology of active layer and crystallinity of crystalline polymer could be demonstrated more easily by the QDs nano-location. The well-segregated p-n interface provide the continuous pathway for efficient charge energy transport. Therefore, 3D visualization and control of active layer morphology can reveal the intimate relations between hybrid active layer morphology and its device performance.
