Abstract
The utility model discloses a solar battery. The solar battery comprises a battery main body, and is characterized in that more than one passivation layer is covered on the surface of the battery main body in an atomic layer deposition manner, and the passivation layer is an alumina layer or a titania layer. The solar battery provided by the utility model has favorable insulativity, resists abrasion and corrosion, and can effectively increase the life cycle of a minority of carriers and enhance the strength of photoluminescence spectrum, thereby having favorable popularization value.
Description
Technical field
The utility model relates to the battery technology field, relates to a kind of solar cell 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.Conventional solar cell sheet surperficial suitable coarse has considerable defective to exist, and the existence of defective will reduce the minority carrier life cycle of solar cell.
Summary of the invention
The purpose of this utility model is exactly provide for the deficiency that solves prior art a kind of simple and reasonable, insulating property (properties) is good, and the erosion-resisting solar cell of abrasion performance.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of solar cell, comprise battery main body, and it is characterized in that described battery main body surface is coated with passivation layer more than one deck in the ald mode.
As further specifying of such scheme, described passivation layer is alumina layer or titanium oxide layer.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
The utility model adopts technique for atomic layer deposition growth aluminium oxide and titanium oxide to form passivation layer; aluminium oxide and titanium oxide are good with insulating property (properties); and abrasion performance is anticorrosive; be considered to goodish protective layer material, the intensity that effectively increases the minority carrier life cycle and strengthen the luminous frequency spectrum of luminescence generated by light.
Description of drawings
Fig. 1 is the utility model structural representation;
Description of reference numerals: 1, battery main body 2, passivation layer.
Embodiment
As shown in Figure 1, a kind of solar cell of the utility model comprises battery main body 1, and battery main body 1 surface is coated with passivation layer 2 more than one deck in the ald mode, and generally speaking, passivation layer is alumina layer or titanium oxide layer.
In the use, aluminium oxide covers on the silicon chip of solar cell with technique for atomic layer deposition as passivation layer, in the atomic layer deposition process, the chemical reaction of new one deck atomic film is directly to be associated with one deck before, and this mode makes each reaction only deposit one deck atom.
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 solar cell comprises battery main body, it is characterized in that, described battery main body surface is coated with passivation layer more than one deck in the ald mode.
2. solar cell according to claim 1 is characterized in that, described passivation layer is alumina layer or titanium oxide layer.
