Abstract
The utility model relates to a back electrode sectional-type solar cell. In the current photovoltaic industry, a mode of screen-printed electrode which is used for producing electrodes is in general use, but the mode has great requirements for large amount of silver paste, thus causing higher cost. The back electrode sectional-type solar cell comprises a crystal silicon wafer, wherein a surface electrode is arranged on the plane of illumination for the crystal silicon wafer; and a back electrode is arranged on the backlighting plane of the crystal silicon wafer. The back electrode sectional-type solar cell is characterized in that two rows of parallel main grid lines are arranged on the back electrode; and the main grid lines are a sectional type structure. The back electrode sectional-type solar cell makes the straight back electrode into the sectional type back electrode so as to reduce consumption of the silver paste, thus significantly reducing the use level of the silver paste and saving the cost, and divides the main grid lines into a three-sectional grid line structure, thus effectively reducing two-thirds of the use level of the silver paste and being convenient and easy for the production process.
Description
Technical field
The utility model relates to a kind of solar battery sheet, especially a kind of back electrode segmented solar battery sheet.
Background technology
What the photovoltaic industry generally adopted now is the mode of screen printing electrode, and both positive and negative polarity is distributed in the two sides of battery, for basic PN junction crystal silicon cell; As shown in Figure 1; Positive two main grid lines 3 are negative pole, and two main grid lines in the back side 3 are anodal, and what the making electrode was used is the silver slurry; Need labor silver slurry, cause cost too high.
The utility model content
The utility model provides a kind of back electrode segmented solar battery sheet to the defective that prior art exists, and effectively reduces silver slurry consumption, practices thrift cost.
For this reason; The utility model is taked following technical scheme: a kind of back electrode segmented solar battery sheet; Comprise crystal silicon chip, on the plane of illumination of crystal silicon chip surface electrode is set, on the shady face of crystal silicon chip backplate is set; Its characteristic is provided with the parallel main grid line of two row on said backplate, described main grid line is a segmentation structure.
A described row main grid line comprises a grid line of three sections equi-spaced apart, the consistent size of described every section grid line.
The utility model is to reduce to consume silver to measure the back electrode of making straight back electrode segmented, significantly reduces silver consuming amount, practices thrift cost.The grid line structure that is divided into the main grid line syllogic can effectively reduce nearly 2/3rds silver medals slurry consumption, and manufacturing process is simple and convenient.
Description of drawings
Fig. 1 is the structural representation of existing battery sheet.
Fig. 2 is the structural representation of the utility model.
Embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technical scheme of the utility model.
Back electrode segmented solar battery sheet as shown in Figure 1; Comprise crystal silicon chip 1, on the plane of illumination of crystal silicon chip 1 surface electrode is set, on the shady face that crystalline silicon is 1 backplate is set; The parallel main grid line of two row is set on the backplate; The main grid line is a segmentation structure, and a row main grid line comprises a grid line 2 of three sections equi-spaced apart, the consistent size of every section grid line 2.This structure approximately can be saved 2/3rds backplane silver slurry, significantly reduces silver slurry consumption, saves cost.
What need particularly point out is; The mode of the foregoing description only limits to describe embodiment; But the utility model is confined to aforesaid way incessantly; And those skilled in the art can modify in the scope that does not break away from the utility model in view of the above easily, so the scope of the utility model should comprise the principle that the utility model discloses and the maximum magnitude of new feature.
