Embodiment Construction

[0033] The problem to be solved by the present invention is to provide a solar cell group and its manufacturing method. The absorption layers of each solar cell in the solar cell group can maximize the photoelectric conversion efficiency without causing current mismatch or lattice mismatch. .

[0034] In order to solve the above problems, the present invention arranges a light-transmitting adhesive material layer between adjacent solar cells of the solar cell group, and the light-transmitting adhesive material layer insulates the two solar cells bonded by it from each other, so that the solar cells are independent of each other ( Independence here means that there can be no electrical conduction between two adjacent solar cells, that is, each solar cell has a separate circuit to export the electricity generated by itself), and there will be no current mismatch between the absorption layers of adjacent solar cells Or the problem of lattice mismatch; the light-transmitting adhes...

Abstract

The invention provides a solar cell module which comprises at least two solar cells arranged in a stacked mode, wherein a nonopaque adhesive material layer is arranged between each two adjacent solar cells and binds the two adjacent solar cells together, and the two solar cells are mutually insulative. Each solar cell in the solar cell module structure is independent, problems of mismatching currents or mismatching crystal lattices do not exist, photoelectric conversion efficiency of absorbed layers of all the solar cells can be maximized, and the photoelectric conversion efficiency of the solar cell module is improved. The invention further provides a manufacturing method of the solar cell module. According to the method, each solar cell can be manufactured independently, and therefore the characteristic of each solar cell can be flexibly adjusted as needed, bulk production of the solar cells can be achieved, the production period of the solar cell module is shortened, and production cost is reduced.

Description

technical field [0001] The invention relates to a solar cell group and a manufacturing method thereof. Background technique [0002] Energy is the driving force for the development of human society and an important material basis for the development of the national economy and the improvement of people's living standards. Conventional energy (mainly fossil energy such as coal, oil, and natural gas) widely used at present is limited, and years of excessive development and utilization have caused serious environmental problems, restricting economic and social development. Therefore, 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. [0003] Tandem solar cells are a new stage in the development of third-gen...
