Abstract
The invention discloses an internal wire for a solar module, made from a conductive copper strap subjected to pretreatment and anti-oxidation treatment. The invention also discloses a processing technique of the internal wire for the solar module. The outer ring of the conductive copper strap of the internal wire for the solar module is provided with no other metal coating, thus the structure is simple and practical; the wire is made from copper only, thus a tinning layer is eliminated, and the conductivity of the wire is enhanced; and the adaptability of a production technique of the solar module is improved.
Description
Technical field
The invention belongs to technical field of solar cells, be specifically related to use lead in a kind of solar module.
Background technology
Develop rapidly and the improving constantly of living standards of the people along with socioeconomic, demand to the energy is also increasing day by day, solar energy is as a kind of sustainable new forms of energy, because of its advantage with energy-conserving and environment-protective has been subjected to extensive favor, at present, solar cell progressively is applied in the daily life field.
The actual utilization of solar cell is assembled into solar photovoltaic assembly with the monomer solar cell and realizes, wherein, welding all plays the effect that is connected solar cell and conduction with the band that confluxes.The existing welding and the band that confluxes belong to the article of two kinds of different sizes, and the welding and the band that confluxes generally are to adopt to be coated with the tin copper strips.
There is following defective with lead (welding or the busbar that refer to noncontact battery sheet part) in the existing solar photovoltaic assembly; 1, conductive capability is lower than copper; 2, processing technology complexity, the cost height; 3, external form bad adaptability.
Summary of the invention
It is a kind of simple in structure, practical that the object of the invention is to provide, and uses lead in the high solar module of conductive capability.
The present invention also aims to provides the processing technology of using lead in the above-mentioned solar module, and this technology is simple, cost is low.
First purpose of the present invention realizes by following technical measures: use lead in a kind of solar module, adopt the conducting copper belt after preliminary treatment and anti-oxidation processing to make.
Described preliminary treatment comprises makes conducting copper belt through annealing with the copper base material again through cutting or after flattening processing.
Described anti-oxidation being treated to adopts chemical reagent that conducting copper belt is carried out anti-oxidation processing.
Second purpose of the present invention is achieved by the following technical solution: with the processing technology of lead, comprise following steps in the above-mentioned solar module:
(1) the copper base material is formed conducting copper belt through cutting or after rolling processing;
(2) annealing in process;
(3) conducting copper belt is promptly prepared through the anti-oxidation processing of chemical reagent.
In above-mentioned processing step:
The temperature of annealing is 150-250 ℃ in the step (2).
Chemical reagent described in the step (3) is copper anti-oxidation (anti-variable color) protective agent, and this copper anti-oxidation (anti-variable color) protective agent can be used as safe anti-spot agent, brightener available from the Ge Sen of Shenzhen Science and Technology Ltd.; Surface protectant; Endurable protection copper product surface oxidation spot rusty stain regeneration.
Wherein, in step (3), use chemical reagent to be penetrated in the space on copper ion surface, the chemical solution on wash clean copper surface then, the moisture on oven dry copper material surface gets final product; chemical solution forms the layer of even diaphragm between the copper ion space, can effectively completely cut off the oxygen of occurring in nature.
The present invention is the copper base material after the employing bandization, it is handled by technology with anti-oxidation reagent, exempt to handle the therefore use that can save tin coating with being coated with tin, because the conductivity of copper is greater than tin, so widened the conductive capability of lead under the identical cross section condition; Simultaneously, because the density of tin is less than copper, so same electrical is led under the situation, the lead thinning has improved solar components processing technology adaptability.
Compared with prior art, tool of the present invention is that following beneficial effect is arranged:
1.. the present invention adopts chemical reagent to carry out anti-oxidation processing at the outer surface of copper conductor, has saved tin coating, has therefore saved the space, has improved the conductive capability of lead;
2.. the present invention has changed the structure of lead, and lead is made up of single copper, has saved to be coated with the tin layer, and the resistivity of copper is 1.75 * 10
-6Ohm. centimetre, the resistivity of tin is 12.6 * 10
-6Ohm. centimetre, so the conductance of the single copper of unit volume to get well, thereby strengthened the conductive capability of lead; And increased solar components production technology adaptability.
