Abstract

The invention relates to an all-black polycrystal high-efficiency photovoltaic assembly and a manufacturing method thereof, belongs to the field of photovoltaic power generation, and aims at solving the problems that a polycrystal photovoltaic assembly in blue cannot be applied to a distributed system as a real black assembly, is low in efficiency, and causes glare pollution. The all-black polycrystal high-efficiency photovoltaic assembly comprises a polycrystal black silicon cell, a frame and a photovoltaic lamination piece; and the photovoltaic lamination piece is in clamp connection with the frame, and comprises a coated glass layer pasted to a first packaging glue film layer, the first packaging glue film layer pasted to a solar cell layer, the solar cell layer pasted to a second packaging glue film layer, the second packaging glue film layer pasted to a backboard, and the backboard in clamp connection with the frame.

Description

technical field [0001] The invention belongs to the field of photovoltaic power generation, and specifically relates to an all-black polycrystalline high-efficiency photovoltaic module and a manufacturing method thereof. Background technique [0002] With the rapid development of social economy and the continuous consumption of energy, people are increasingly aware of the limitations of non-renewable energy sources such as oil, and people are constantly trying to develop new energy sources, such as wind energy, tidal energy, solar energy, etc., to cope with the upcoming energy crisis. As an efficient, pollution-free renewable resource, solar energy has been gradually utilized by all walks of life, and the country is also vigorously supporting projects such as photovoltaic poverty alleviation. In recent years, distributed photovoltaic systems have developed rapidly. Due to people's requirements for roof appearance, black components occupy an important position in distributed ...
