Abstract
The utility model provides a solar cell with a gradient structure outer frame grid line. The solar cell comprises a silicon chip, main gate lines arranged on the silicon chip, auxiliary gate lines arranged on the silicon chip, and an outer frame gate line, wherein the main gate lines are connected with the auxiliary gate lines, and the outer frame gate line is extended along edges of the silicon chip to form a loop. According to the outer frame gate line of the utility model, on one hand, all main gate lines and auxiliary gate lines are in electrical communication, so that even the main gate lines and the auxiliary gate lines are in false welding, the auxiliary gate lines still can be connected to the main gate lines through the outer frame gate line, on the other hand, false welding can be prevented due to a board part of the outer frame gate line, the reduction of a light shading area is facilitated due to a narrow part of the outer frame gate line, and the work efficiency of the cell is raised.
Description
Technical field
The utility model relates to solar cell, particularly, relates to the solar battery sheet with grading structure housing grid line.
Background technology
The photovoltaic panel assembly is that a kind of exposure just can produce galvanic Blast Furnace Top Gas Recovery Turbine Unit (TRT) in the sun, and the solid photovoltaic cell of basically mainly making with semiconductor material (for example silicon) forms, and comprises P type semiconductor and N type semiconductor.P type semiconductor (P refers to positive, positively charged): mix a small amount of triad by monocrystalline silicon by special process and form, can be in the inner hole that forms positively charged of semiconductor; N type semiconductor (N refers to negative, and is electronegative): mix a small amount of pentad by monocrystalline silicon by special process and form, can be at the electronegative free electron of the inner formation of semiconductor.
Many positively charged holes and electronegative ionized impurity are arranged in P type semiconductor.Under the effect of electric field, the hole is transportable, and ionized impurity (ion) is fixed.Many movable negatrons and fixing cation are arranged in the N type semiconductor.When the P type contacts with N type semiconductor, spread to N type semiconductor from P type semiconductor in the near interface hole, electronics spreads to P type semiconductor from N type semiconductor.Hole and electronics meet and compound, and charge carrier disappears.Therefore in the interface of near interface, there is a segment distance to lack charge carrier, the charged fixed ion that is distributed in the space is but arranged, be called the space charge region.P type semiconductor space charge on one side is anion, and N type semiconductor space charge on one side is cation.Negative ions produces electric field near interface, and this electric field stops charge carrier further to spread, and reaches balance.
When light frequency surpasses a certain limiting frequency, be subjected to light-struck solar panel surface photoelectron of will overflowing immediately, photoelectric effect occurs.When adding a closed circuit in the solar panel outside, add the forward power supply, the photoelectron of these effusions all arrives anode and just forms photoelectric current.
Electrode pattern of the prior art arranges to improve battery efficiency thick and fast by secondary grid line, but it has also brought simultaneously the too meticulous rosin joint that is connected to that causes easily itself and main grid line of secondary grid line, and impact is to the enrichment of electric charge.
