Fig. 5: Phase distribution in mixed-dimensional 2D/3D film for solar cells.

a Schematic illustration of the depth-profile phase distribution of the gradient mixed-dimensional film in the traditional opinion (the left panel) and that in the practical situation (the right panel). The yellow rectangle (and the yellow part) represents the 2D HP component, and the red part represents the 3D HP component. b The cross-section SEM micrograph of the gradient mixed-dimensional film. The scale bar is 500 nm.
