Abstract

The invention discloses preparation methods of a three-dimensional flexible transparent electrode and a modified inversion solar cell. The preparation method of the three-dimensional flexible transparent electrode comprises the following steps: (1), carrying out plasma treatment on a PET substrate; (2), carrying out magnetron sputtering treatment on the PET substrate after plasma treatment, plating the PET substrate with a lower ZnO film, a AgOx film and an upper ZnO film, and forming a three-dimensional flexible transparent electrode is formed on the PET substrate. The prepared electrode hasa three-dimensional form, so that the transmission distances between electrons and hole pairs in exciton are reduced, the recombination of holes and electrons is reduced effectively, and absorption ofthe sunlight by the light active layer is increased. Moreover, the three-dimensional nanoparticle have good scattering effect on sunlight, so that the transmission path of the sunlight in the activelayer is increased and thus the absorption of the sunlight by the light active layer is enhanced. Therefore, with the electrode having the three-dimensional form, the photoelectric conversion efficiency and stability of the solar cell can be improved.

Description

technical field [0001] The invention relates to the interdisciplinary field of solar cell preparation technology, in particular to a preparation method of a three-dimensional flexible transparent electrode and a modified inverted solar cell. Background technique [0002] The combination of polymer photoactive layer and nanostructured transparent conductive electrode provides a direct and defined charge transport channel, which is an effective way to prevent the recombination of invalid charges in the active layer and improve the energy conversion efficiency of PSCs. The three-dimensional electrodes in the vertical direction prepared by the porous mold method or the direct nanorod growth method can provide more direct transport channels for charges and have a larger surface structure, so they have better charge transport and photocurrent than thin film electrodes. Collect performance. Since the preparation of high-aspect-ratio TCO electrodes usually requires high-temperature...
