Abstract
The utility model discloses a crystal silicon solar cell, which comprises a cell body and is characterized in that a layer of silver is electroplated on a front grid line of the cell body. The crystal silicon solar cell can reduce the series resistance and improve a fill factor and photoelectric conversion efficiency, thereby having good promotion value.
Description
Technical field
The utility model relates to the battery technology field, relates to a kind of crystal silicon solar battery more specifically.
Background technology
Solar cell is that a kind of photovoltaic effect of utilizing becomes the device of electric energy to transform light energy, is photovoltaic device again.Converting solar energy the solid semiconductor device of electric energy to, claim solar cell or photocell again, is the critical elements of solar battery array power-supply system.Solar cell mainly contains monocrystalline silicon battery and monocrystalline GaAs battery etc.The stock of single crystal silicon solar cell is that purity reaches 0.999999, the p type single crystal silicon of resistivity more than 10 Europe centimetre; comprise parts such as p-n junction, electrode and antireflective coating; be subjected to plane of illumination to add printing opacity cover plate (as quartzy or ooze cerium glass) protection, prevent that battery is subjected to the radiation damage of high energy electron and proton in the Van Allen belt of outer space.At present, all have a certain proportion of inefficient solar cell to produce every day in the factory.By analysis, wherein very major part is because battery goes wrong in sintering circuit, and burning or underburnt all can make the series resistance of battery raise, and reduce fill factor, curve factor and photoelectric conversion efficiency.
Summary of the invention
The series resistance that the purpose of this utility model is exactly provide for the deficiency that solves prior art a kind of simple and reasonable, can reduce battery improves the crystal silicon solar battery of fill factor, curve factor and photoelectric conversion efficiency.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of crystal silicon solar battery, comprise battery main body, and it is characterized in that, electroplate one deck silver on the front gate line of described battery main body.
As further specifying of such scheme, described silver coated battery front side grid line live width is the 40-100 micron.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
The utility model uses traditional electro-plating method, electroplates the thin silver of one deck on the front gate line of inefficient battery, can reduce the series resistance of battery, improves fill factor, curve factor and photoelectric conversion efficiency.
Description of drawings
Fig. 1 is the utility model structural representation;
Description of reference numerals: 1, battery main body.
Embodiment
As shown in Figure 1, a kind of crystal silicon solar battery of the utility model comprises battery main body 1, electroplates one deck silver on the front gate line of battery main body 1, and the grid line live width is the 40-100 micron.
In the preparation process, use traditional electro-plating method, on the front gate line of inefficient battery, electroplate the thin silver of one deck, though simple to operate, can reduce the series resistance of battery, improve fill factor, curve factor and photoelectric conversion efficiency.
Above-described only is preferred implementation of the present utility model; should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the utility model creation design; can also make some distortion and improvement, these all belong to protection range of the present utility model.
Claims (2)
1. a crystal silicon solar battery comprises battery main body, it is characterized in that, electroplates one deck silver on the front gate line of described battery main body.
2. crystal silicon solar battery according to claim 1 is characterized in that, described silver coated battery front side grid line live width is the 40-100 micron.
