Abstract
The utility model relates to a photoelectric device, in particular to a solar cell, which comprises a silicon slice, a main grid line and a branch grid line, which are etched on the silicon slice and are intersected with each other and the branch grid line is provided with a fine grid line. Under the situation that the technique is not changed and the production equipment is not replaced, the charge accumulation capacity of the solar cell can be improved, so the power generating efficiency of the solar cell can be improved.
Description
Technical field
The utility model relates to a kind of electrooptical device, relates in particular to a kind of solar battery sheet.
Background technology
Solar power generation is owing to its environmental protection and reproducible performance, and the parent who more and more receives 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, the grid line on the silicon chip, its main grid line, the straight line of a grid line for intersecting, and the main grid line is thicker.The electric charge that solar radiation is radiated on the silicon chip to be produced is transferred on the main grid line by a grid line enrichment of metal then, produces electric current, generates electricity.But solar battery sheet in the market is because a grid line is a straight line, and total length is short, and a little less than the ability of enrichment electric charge, a large amount of electric charges that produced by illumination are not by enrichment, so solar battery sheet generating efficiency in the market is low.If but changing technology and production equipment on a large scale, cost is too high so, and medium and small manufacturer can't bear.How under the situation of not changing process equipment, to transform solar battery sheet simply and easily, make it to improve generating efficiency, just inventor's problem that will solve.
Summary of the invention
The utility model has promoted the generating efficiency of solar battery sheet simply and easily, and its concrete technical scheme is: a kind of solar battery sheet, and the main grid line, the grid line that comprise silicon chip and be etched on the silicon chip and intersect, said grid line is provided with thin grid line.
As preferably, said thin grid line is semicircle.
As preferably, said thin grid line is a half elliptic.
As preferably, said thin grid line is for dividing the oblique line of the grid line both sides of being disbursed from the cost and expenses.
As preferably, said thin grid line is for dividing the right angle folding of the grid line both sides of being disbursed from the cost and expenses.
As preferably, said thin grid line is tree-like.
The utility model is not changed under the situation of production equipment not changing technology, has promoted the ability of solar battery sheet enrichment electric charge, thereby has improved the generating efficiency of solar battery sheet.
