Description
Technical field
The present invention belongs to field of solar energy, is meant a kind of solar battery chip protection structure especially.
Background technology
Solar cell is a kind of because the photovoltaic special efficacy is answered and solar energy is converted into power devices.When solar irradiation is to solar cell, will become electric energy to the luminous energy of the sun, produce electric current.When being together in series or parallel, a plurality of solar cells just can become solar cell matrix that big power output is arranged.Solar cell is a kind of coming novel energy, has persistence, spatter property and flexibility three big advantages.Solar battery life is long, as long as sunlight exists, solar cell just can once be invested and the longer-term use; Compare with thermal power generation, nuclear energy power generation, solar energy itself is that a kind of environment-friendly and green energy can not cause environmental pollution; Solar cell can large, medium and smallly develop simultaneously, and arrives the medium-sized power station of gigawatt greatly, and little of the solar battery group of only using for a family, this is that other power supply is incomparable.
Further extensive use along with solar energy, high light intensity can improve the fill factor of solar cell and effectively reduce cost in field of solar energy, but the too strong temperature rise meeting of light makes pcb board fusing or fracture outside the chip, so it is most important to handle " remaining optically focused outside the chip " scientifically and rationally, this point is one of entire cell key in application problem, has directly determined the life-span of solar concentrating system; Another key issue is that the inhomogeneous meeting of light intensity that receives on the same solar cell chip reduces its fill factor, thereby influences battery efficiency and life-span, finally also causes the raising of cost.Therefore handling " remaining optically focused outside the solar chip " and " uniformity " in the gathered light system is crucial in the application of whole solar energy light-collecting battery, and also not proposing on market at present can solution of the above problems.
Summary of the invention
Main purpose of the present invention provides a kind of solar battery chip protection structure, and it can prevent that pcb board outside the chip from melting because of temperature rise is too high or rupture, and effectively prolongs the life-span of solar cell.
Secondary objective of the present invention provides a kind of solar battery chip protection structure; it can effectively improve solar cell glazed thread " uniformity "; overcome the disappearance point of concentrating solar battery, give full play to its advantage, improve the effective rate of utilization of solar cell greatly.
For achieving the above object; solution of the present invention is: a kind of solar battery chip protection structure; be provided with a condenser on battery chip top, wherein: the position of the corresponding battery chip size of this condenser is provided with transparent area, and is reflective areas in the transparent area outer rim of condenser.
Described condenser is a plate glass.
Be coated with reflectance coating on the described reflective areas.
Described reflective areas is reflective lens.
Be coated with reflectance coating on the described reflective lens.
Described reflective areas is provided with reflective device.
Described transparent area is an obscured glass.
Described transparent area is a toroidal lens.
After adopting such scheme, the present invention is divided into transparent area and reflective areas with the condenser on the battery chip, and the size of the transparent area size of corresponding chip just in time, then chip can effectively be collected sunlight; In addition the optically focused that utilizes is reflected by reflective areas or sponges in order to avoid expose to pcb board not needing outside the solar chip, causes temperature rise that pcb board is melted or breaks, and effectively prolongs useful life of solar cell with this.
And being carried out hair side, transparent area handles or is made as the optical surface lens, can make the light of injecting chip by hair side diffuse reflection or the catadioptric of toroidal lens from new distribution, make it to be incident to the equalizing light rays distribution of chip, improve the fill factor of solar cell chip, overcome the disappearance point of concentrating solar battery, give full play to its advantage, improve the effective rate of utilization of solar cell greatly.

Embodiment
Cooperate Fig. 1 to shown in Figure 7; solar battery chip protection structure of the present invention; be to be provided with a condenser 1 on solar battery chip 2 tops, wherein: the position of these condenser 1 corresponding battery chip 2 sizes is provided with transparent area 11, and is reflective areas 12 in transparent area 11 outer rims of condenser 1.
The size of the just in time corresponding battery chip 2 of the size of transparent area 11, then battery chip 2 can effectively be collected sunlight; In addition the optically focused that utilizes is reflected by reflective areas 12 or sponges in order to avoid expose to pcb board not needing outside the solar chip 2, causes temperature rise that pcb board is melted or breaks, and effectively prolongs useful life of solar cell with this.
Be embodiments of the invention 1 as shown in Figure 1, 2, this condenser 1 is a plate glass, the zone of corresponding battery chip 2 sizes in middle part is a transparent area 11, forms or be provided with reflective device realization and be coated with reflective membrane on the reflective areas 12 employing surfaces of transparent area 11 peripheries on reflective areas 12.
Be depicted as embodiments of the invention 2 as Fig. 3,4, wherein transparent area 11 is to adopt to carry out the frosted glass that hair side is handled, and being provided with above-mentioned embodiment 1 of transparent area 11 do not given unnecessary details at this.Transparent area 11 is adopted hair side the light that is incident to battery chip 1 is evenly distributed herein, cooperate shown in Figure 5, hair side homogenizing light principle explanation: conventional collected light because of under the catadioptric effect of optical lens (be surface normal have specific distribution and towards), the direction of propagation of light also is tending towards a specific zonule and direction, so just cause the light intensity in the zone on the specific direction than higher, other just lower, form intensity gradient clearly, promptly we say usually inhomogeneous; In this situation, we introduce hair side, scraggly approximate " " (conventional 20# granularity just can realize face R because of the surface of hair side has, the efficient of different grain size correspondence is also different, do not describe in detail at this), the surface normal that different trends are promptly arranged, like this if having specific distribution and towards light get on this face, a series of catadioptric will take place, form our so-called diffuse reflection promptly had originally specific distribution and towards the effect of light at frosted glass under redistribute, make the light of outgoing just relatively more even in the distribution of all directions, (probability even odds) improves the fill factor of solar cell chip 2, overcomes the disappearance point of concentrating solar battery, give full play to its advantage, improve the effective rate of utilization of solar cell greatly.
Be depicted as embodiments of the invention 3 as Fig. 6,7, being provided with embodiment 1 of its reflective areas 12 no longer described in detail; And transparent area 11 can adopt toroidal lens, and its principle can reach " uniformity " of solar cell glazed thread equally with above-mentioned embodiment 2, improves the effect of solar cell effective rate of utilization.
