Technical Field
The utility model belongs to solar cell preparation technique, in particular to calibration battery piece that realizes calibration of different main bars interval battery piece efficiency.
Background
Solar photovoltaic power generation is a clean and efficient energy utilization mode, is generally concerned all over the world, and is a strategic emerging technology industry of national key development.
With the development of the photovoltaic industry, the design of cell patterns of each manufacturer is different, mainly the main grid intervals have a certain difference, when the pattern cells with different main grid intervals are switched to produce, in order to ensure the consistency of efficiency tests of the pattern cells with different main grid intervals, the efficiency of the cells produced for the first time needs to be calibrated, usually, the cells produced for the first time are sent to a third party for efficiency calibration, however, the efficiency calibration time of the cells produced for the first time with different main grid intervals is increased by the method, and therefore the stability of the working efficiency during product switching cannot be ensured.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a realize calibration battery piece of different main bars interval battery piece efficiency calibration, both can ensure the uniformity of different main bars interval battery piece efficiency, reduced the different main bars interval battery piece efficiency calibration time of first production again.
The purpose of the utility model is realized through the following technical measures: the calibration battery piece is characterized in that the main grid lines on the calibration battery piece comprise two main grid lines with different intervals, and the main grid lines with one interval are calibrated according to the efficiency of the battery piece.
The utility model discloses a main grid line of one of them interval has passed through battery piece efficiency and has markd, when the main grid line battery piece production of another kind of interval is switched into to needs, can this carry out efficiency calibration fast for the benchmark to guarantee that different main bars interval battery piece efficiency keeps unanimous, reduce the different main bars interval battery piece efficiency calibration time of first production simultaneously.
As a preferred embodiment of the present invention, the two main grid lines with different pitches are two main grid lines with the same number and different pitches.
As another preferred embodiment of the present invention, the two main grid lines with different pitches are two main grid lines with different numbers and different pitches.
Compared with the prior art, the utility model discloses the effect that is showing as follows has:
the utility model discloses a main grid line of one of them interval has passed through battery piece efficiency and has markd, when the main grid line battery piece production of another kind of interval is switched into to needs, can this carry out efficiency calibration fast for the benchmark to guarantee that different main grid interval battery piece efficiency keeps unanimous, reduce the different main grid interval battery piece efficiency calibration time of first production simultaneously.

Drawings
The present invention will be described in further detail with reference to the following drawings and specific embodiments.
Fig. 1 is a front view of the present invention.
Detailed Description
As shown in fig. 1, it is the utility model relates to a calibration battery piece 1 of realizing calibration of different main grid interval battery piece efficiency, the main grid line on the calibration battery piece 1 includes the main grid line of two kinds of intervals differences. In this embodiment, the two kinds of main gate lines with different pitches are two kinds of main gate lines 2 and 3 with the same number and different pitches, the number of the two kinds of main gate lines 2 and 3 with different pitches is 9, the middle main gate lines of the two kinds of main gate lines 2 and 3 are overlapped, and the rest main gate lines are symmetrically distributed with the middle main gate lines as a central axis.
The main grid lines at one interval are calibrated by the efficiency of the battery piece, and when the battery piece is switched to the production of the battery piece with the pattern at the other main grid interval, the efficiency calibration can be quickly carried out by taking the main grid lines as a reference, so that the efficiency of the battery pieces with different main grid intervals is kept consistent, the efficiency calibration of the patterns with different main grid intervals is realized, and the efficiency calibration time of the battery pieces with different main grid intervals in the primary production is reduced.
In other embodiments, the number of the two main grid lines with the same number and different pitches may be other numbers, and the pitch may be determined according to actual conditions; the two kinds of main grid lines with different intervals can also be two kinds of main grid lines with different numbers and different intervals, and the number and the intervals of the main grid lines can be determined according to actual conditions.
The embodiments of the present invention are not limited to the above, according to the above-mentioned contents of the present invention, according to the common technical knowledge and the conventional means in the field, without departing from the basic technical idea of the present invention, the present invention can also make other modifications, replacements or changes in various forms, all falling within the scope of the present invention.
