Description
Technical field
The invention belongs to technical field of photovoltaic power generation, feature is related to a kind of photovoltaic cell component back veneer material.
Background technique
The primary structure of photovoltaic cell includes photoelectric conversion unit, protects the encapsulating material of circuit, shell and other match
Nested structure.In order to guarantee the luminous efficiency and service life of photoelectric conversion unit, prevent photoelectric conversion unit from circuit leakage occur
The reasons such as electricity, corrosion lead to luminous efficiency decline and the lost of life, it is desirable that the backboard of photoelectric conversion unit is keeping some strength
While, also require have high barrier property, i.e. barrier steam is contacted with photoelectric conversion unit, prevented in photoelectric conversion unit
There is the generation of electrochemical reaction in portion.Backboard in present photovoltaic cell component uses pure aluminum metal piece, and pure aluminum metal
For piece when thickness is lower than 15um, there are pin hole problems, and this case can seriously damage photoelectric conversion unit.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides one kind can be improved metal ductility, reduces what pin hole occurred
Photovoltaic cell component back veneer material.
The technical solution adopted in the present invention is as follows: a kind of photovoltaic cell component back veneer material, including presses mass fraction
The following ingredient of meter: 15~25 parts of chromium, 10~15 parts of nickel, 1~7 part of tantalum, 80~95 parts of aluminium.
Preferably, a kind of photovoltaic cell component back veneer material, including following ingredient according to the mass fraction: chromium 16~
20 parts, 10~13 parts of nickel, 3~6 parts of tantalum, 85~90 parts of aluminium.
Most preferably, a kind of photovoltaic cell component back veneer material, including following ingredient according to the mass fraction: chromium 18
Part, 12 parts of nickel, 4 parts of tantalum, 86 parts of aluminium.
Preferably, the back veneer material of the photovoltaic cell component is with a thickness of 10~15um.
The technical effect that above-mentioned technical proposal can be realized is as follows: the present invention can improve photovoltaic cell component backboard
While material metal ductility, the appearance of pin hole is reduced, can be effectively reduced cost；And according to technical scheme
The generation of photoelectric conversion unit electrochemical reaction can be prevented by matching the back veneer material made.
