Abstract
The utility model discloses a battery piece with high conversion efficiency, belongs to the technical field of solar battery piece design, and aims at providing a solar battery piece that can reduce the rupture of the battery piece, prolong the service life of the battery piece, and improve the light availability of the battery piece. The battery piece is characterized in that the battery piece comprises a battery piece main body, wherein main grid lines that are arranged in parallel are arranged on the battery piece main body; a plurality of thin grid lines are arranged among the main grid lines; the thin grid lines are formed by connecting rhombuses through vertexes; and the main grid lines and the thin grid lines are arranged straight to a net structure.
Description
Technical field
The utility model discloses a kind of cell piece, specifically, is the high cell piece of a kind of conversion efficiency, belongs to the solar battery sheet design field.
Background technology
Solar power generation is due to its environmental protection and reproducible performance, and the parent who more and more is subject to people looks at.The principle of solar cell power generation is based on semi-conductive photovoltaic effect, and solar radiation is converted into electric energy.Solar battery sheet in the market comprises silicon chip and is etched in main grid line on silicon chip, a grid line, its main grid line, the straight line of a grid line for intersecting, and the main grid line is thicker.Solar radiation is radiated at the electric charge that produces on silicon chip by a grid line enrichment of metal, then is transferred on the main grid line, and generation current generates electricity.But solar battery sheet generating efficiency in the market is lower, and profile is not attractive in appearance, because the main body of cell piece own is silicon, is answering pressure like this when welding.
The utility model content
For the problems referred to above, the utility model provides a kind of breaking of cell piece of reducing, and has increased the useful life of cell piece, improves the solar battery sheet of the light availability of cell piece.
The technical solution of the utility model is such: the cell piece that a kind of conversion efficiency is high, comprise the cell piece main body, described cell piece main body is provided with the main grid line that is arranged in parallel, be provided with many thin grid lines between the main grid line, thin grid line is formed by connecting by the summit by rhombus, and the main grid line reticulates structure with the thin in line row of grid line.
Further, the above-mentioned high cell piece of a kind of conversion efficiency, the width of described thin grid line is 0.2～0.4mm.
Further, the above-mentioned high cell piece of a kind of conversion efficiency, described cell piece main body is provided with 3 main grid lines that are arranged in parallel.
Compared with prior art: technical scheme provided by the utility model, reduce the phenomenon of rupture that the main grid line produces due to effect of stress, avoid solar battery sheet fragmentation or the hidden generation of splitting, increased the useful life of cell piece, improve the light availability of cell piece, the performance of cell piece is more stable.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Wherein: cell piece main body 1, main grid line 2, thin grid line 3.
Embodiment
Below in conjunction with embodiment, the technical solution of the utility model is described in further detail, but does not consist of any restriction of the present utility model.
Consult shown in Figure 1, the high cell piece of a kind of conversion efficiency of the present utility model, comprise cell piece main body 1, described cell piece main body 1 is provided with three main grid lines 2 that are arranged in parallel, main grid line 2 is used for collected current, compare the cell piece of conventional two main grid lines 2, increased the light availability of cell piece.Be provided with many thin grid lines 3 between main grid line 2, thin grid line 3 is formed by connecting by the summit by rhombus, the width of thin grid line is 0.2～0.4mm, optimum width is 0.3mm, this diamond structure is conducive to increase thin grid line 2 and bears the compression chord of cell piece main body 1, and main grid line 2 reticulates structure with thin grid line 3 vertical arrangements.Be the angle of 45 ° between the thin grid line 3 of diamond array and main grid line 2, this angle has effectively reduced the component of welding direction.During manufacturing, main grid line 2 and thin grid line 3 cell panel manufacture method routinely, burn on cell piece main body 1 through silk screen printing, oven dry, knot, forms at 700 ℃ of sintering.
