Abstract

A solar cell module and a preparation method therefor. The solar cell module has a composite electron transport layer (4), and the composite electron transport layer (4) comprises: a light scattering layer (41), which is used for absorbing first light and performing scattering; a first electron transport layer (42), which is located on the surface of one side of the light scattering layer (41), and is used for transporting electrons and filling voids in the light scattering layer (41); and a second electron transport layer (43), which is located on the surface of the side of the first electron transport layer (42) away from the light scattering layer (41), wherein there is a conduction band offset between the first electron transport layer (42) and the second electron transport layer (43). In the composite electron transport layer (4) of the solar cell module, the light scattering layer (41) can increase light scattering, and the first electron transport layer (42) can fill the voids formed by the agglomeration of nanoparticles in the light scattering layer (41), thereby reducing surface roughness. In addition, the first electron transport layer (42) and the second electron transport layer (43) that have a conduction band offset can accelerate electron transport, and by means of the synergistic cooperation of the three layers, the electron transport efficiency and stability of the composite electron transport layer (4) can be significantly improved.
