| titleOfInvention | Preparation method of PERC flexible graphene/silicon solar cell |
| abstract | The invention discloses a preparation method of a PERC flexible graphene/silicon solar cell, and belongs to the field of solar cells. According to the invention, a silicon wafer with a nano structure and ultrathin flexibility is obtained by a one-step preparation technology of a flexible nano-textured silicon wafer, the surface of the silicon wafer is passivated by adopting a chemical passivation method or/and a field passivation method, then the surface of the silicon wafer is modified by adopting a dropping coating method, a spin coating method, a wet transfer method or a magnetron sputtering method, then a conducting layer and a transfer layer graphene are introduced, and finally an electrode is connected to complete the preparation of the flexible graphene/silicon solar cell. The metal nano-particle assisted chemical etching method realizes large-scale controllable preparation of the nano structure on the surface of the silicon substrate so as to realize the purpose of increasing spectral absorption of the silicon substrate and simultaneously achieving the purpose of thinning the silicon substrate to obtain flexible silicon; the PERC flexible graphene/silicon solar cell structure is an ultrathin flexible cell with the thickness of 1-100 mu m. |
