Abstract
Provided is a solar energy assembly with high conversion rate, comprising a cathode layer, an N type silicon layer, a P type silicon layer, and an anode layer which are sequentially laminated. The solar energy assembly of the utility model is further provided with a passivation layer arranged between the cathode layer and the N type silicon layer. The silicon dioxide layer of the utility model, arranged between the anode layer and the P type silicon layer, is provided with the gettering and passivation functions.
Description
Technical field
The utility model relates to technical field of solar batteries, particularly a kind of solar components of high conversion.
Background technology
Solar module also is solar panel, is the core in the solar power system, also is most important part in the solar power system.Solar cell is the device that directly light energy conversion is become electric energy by photoelectric effect or Photochemical effects.Solar cell more and more receives people's concern as green energy resource.The crystalline silicon material quality plays vital effect to the efficient of solar cell, and crystalline silicon substrate material surface defect concentration is very high, such as a large amount of dangling bonds, impurity and scission of link etc., causes the silicon chip surface minority carrier life time greatly to reduce, and recombination rate is lower.
The utility model content
The purpose of this utility model is to overcome the defective that prior art exists, and provides a kind of conversion efficiency high solar components.
The technical scheme that realizes the utility model purpose is: a kind of solar components of high conversion has the negative electrode layer, N-type silicon layer, P type silicon layer and the anodal layer that stack gradually; Also has passivation layer; Described passivation layer is arranged between negative electrode layer and the N-type silicon layer.
The described passivation layer of technique scheme is silicon dioxide layer.
The described negative electrode of technique scheme and positive electrode are aluminium lamination.
The surface of the described negative electrode layer of technique scheme is provided with main grid and the secondary grid vertical with main grid and that equidistantly distribute that form by the half tone graphic printing.
Have back electrode and back of the body electric field on the described anodal layer of technique scheme.
After adopting technique scheme, the utlity model has following positive effect:
(1) passivation layer of the present utility model is arranged between anodal layer and the P type silicon layer; Passivation layer is silicon dioxide layer, and silicon dioxide layer has the effect of gettering, passivation.
(2) the utility model is used silver paste and is made electrode and back of the body electric field, optimize graphic designs, not only guarantee the planarization of the good conductivity of electrode, solderability and back of the body electric field, had more the printing performance of excellence, the advantage that adhesive force is high, flexibility is low and conversion efficiency is high.
Description of drawings
Content of the present utility model is easier to be expressly understood in order to make, and the below is described in further detail the utility model, wherein according to specific embodiment also by reference to the accompanying drawings
Fig. 1 is structural representation of the present utility model;
1. negative electrode layers among the figure, 11. main grids, 12. secondary grid, 2.N type silicon layer, 3.P type silicon layer, 4. anodal layer, 41. back electrodes, 42. back of the body electric field, 5. passivation layers.
