Core layer of perovskite nanowire with tiled shell-core structure and solar cell manufacturing method of core layer

Abstract

The invention discloses a core layer of a perovskite nanowire with a tiled shell-core structure and a solar cell manufacturing method of the core layer. Sunlight can directly enter from the front surface of a cell without entering from the side surface, so the efficiency of a device is improved, and the core layer is very suitable for the fields of intelligent wearing and the like. The core layermanufacturing method comprises the following steps: a, preparing a substrate and a template; b, etching a tiled groove array on the template by adopting an electron beam exposure method; c, enabling the groove of the template to face downwards, bonding and fixing the template and the substrate together, forming an accommodating space of the core layer between the groove and the substrate, and soaking the core layer in the core layer sol until the accommodating space is filled with the core layer sol; d, drying and annealing to form a tiled array type core layer. The manufacturing method of thecell comprises the following steps: S1, arranging a first electrode at one end of a substrate; S2, preparing a core layer on the substrate; S3, preparing a shell layer on the core layer; S4, arranging a second electrode at the other end of the substrate.

Description

Technical field [0001] The invention relates to the technical field of solar cells, in particular to a method for manufacturing a solar cell and a method for preparing a core layer by a template method. Background technique [0002] Nanowires with perovskite materials as the shell and transport materials as the core layer are expected to achieve high photoelectric conversion efficiency for solar cells. At present, the traditional shell-core structure nanowire arrays are all upright structures. If the shell-core structure perovskite nanowire arrays using perovskite materials as the light-absorbing layer are applied to solar cells, the sunlight needs to be incident from the side of the cell , Affecting the performance of the device. Summary of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a method for manufacturing a solar cell and a method for preparing a core layer by a template method. The sunlight does n...
