Solar cell module

Abstract

The present invention relates to the field of solar cell, and provides a solar cell module. The solar cell module is characterized in that: an aluminum electrode (2) is prepared on a backlight surfaceof an n-type silicon wafer (1), a light receiving surface of the n-type silicon wafer (1) is provided with a p-n junction layer (3), a first passivation layer (4), a second passivation layer (5), a third passivation layer (6) and an anti-reflection coating (7) in order; and a silver electrode (8) is prepared on the light receiving surface. The silicon wafer (1) comprises a monocrystalline siliconchip or a polycrystalline silicon chip. The first passivation layer (4) is a silicon oxide passivation layer, the second passivation layer (5) is an alumina passivation layer, and the third passivation layer (6) is a silicon nitride passivation layer. The anti-reflection coating is a silicon nitride anti-reflection coating. The photoelectric conversion efficiency of the solar cell can be improved.

Description

technical field [0001] The invention relates to the field of solar cells, in particular to a solar cell component. Background technique [0002] With the development of society, the energy problem has become a severe challenge faced by all mankind. At present, my country's energy structure and energy security have increasingly become the bottleneck restricting sustainable development. Therefore, more and more countries have begun to seek new impetus for economic development through the development of solar energy resources. [0003] The application of solar cell modules is more and more extensive. From traditional large-scale solar power plants to small residential systems, solar power generation can be seen everywhere. However, the power generation efficiency of solar cells has always been a difficult problem in this field. Contents of the invention [0004] Aiming at the above problems, the present invention proposes a solar cell module, which improves the photoelectr...
