A kind of thin-film solar cell and its manufacturing method

Abstract

The invention discloses a thin film solar cell and a production method thereof. The thin film solar cell comprises a core, a thin film cell layer and a packaging material which is arranged between the core and the thin film cell layer and used for packaging the thin film cell layer on the core, wherein the thin film cell layer comprises a protective layer, a back electrode layer, a generating layer, a transparent conductive layer and a transparent soft liner, the protective layer, the back electrode layer, the generating layer, the transparent conductive layer and the transparent soft liner are arranged sequentially from inside to outside, the packaging material is sleeved outside the core, and the packaging material and the core have the consistent shape and are in a non-panel solid structure. The thin film solar cell layer is packaged on the core with the solid shape, the structure is reasonable, the production is convenient, various shapes can be produced in accordance with use occasion requirements, the limit is little in materials, the limit on cost, devices and process is free, and the application prospects of the cell is expanded.

Description

technical field [0001] The invention relates to the field of solar cells, in particular to a thin-film solar cell and a manufacturing method thereof. Background technique [0002] Energy is the driving force for the development of human society, and the development of renewable energy is one of the key issues related to the national sustainable development strategy. Among various renewable energy sources, solar photovoltaic power generation technology is the fastest-growing and most cutting-edge research field in the field of solar energy utilization in recent years. Thin-film solar cells have become a research hotspot due to the advantages of less consumables, low manufacturing costs, and less pollution. Current thin-film solar cells can be divided into rigid substrates (such as glass) and flexible substrates (such as resin) according to the substrate. [0003] At present, thin-film solar cells are limited by production equipment and technology, and are basically planar. ...

AI Technical Summary

Problems solved by technology

Although this process method can be realized, it has the following defects: 1) Since the film is coated on the cylindrical substrate, the substrate needs to enter the production line in the whole process, so the requirements for the material of the substrate are very high, which increases the cost of the substrate. Cost; 2) Because the equipment for coating the cylindrical substrate is incompatible with the existing coating equipment, special customization is required, and it is very expensive, thus increasing the equipment cost; 3) Due to the production process of the cylindrical substrate and the The coating process on it is relatively complicated, so the production efficiency is low and the yield is low
