Background technology
With social continuous progress, pollute increasingly severe, develop renewable, free of contamination new forms of energy and have become as society
Inevitable trend can be developed.At present, relatively common new forms of energy have: solar energy, wind energy, water energy, tide energy etc., wherein solar energy
It is relatively common new forms of energy in daily life, and photovoltaic cell is exactly the device that a kind of solar energy is converted into electric energy, in light
Generally optically focused conversion electric energy is carried out using polysilicon and monocrystal silicon on volt battery, but this method conversion ratio is relatively low, general turn
Rate is only below 17%, and produces and maintenance cost height, installs inconvenient.
In prior art, a kind of such as disclosed " the optically focused crystalline silicon of Chinese invention patent application publication No. cn103546096a
Solar module ", including optically focused crystal silicon solar battery component, its by condenser, monocrystalline silicon photovoltaic power generation device,
Heat radiation cooling device and sun tracker composition, feature is: monocrystaline silicon solar cell is arranged on sun tracker, single
The top of crystal silicon solar batteries is provided with condenser, and the bottom of monocrystaline silicon solar cell is provided with heat radiation cooling device.
This technical scheme deficiency in actual use is: 1. caustic surface section is in horn-like, makes cannot closely arrange between assembly
Row, greatly reduce electric energy conversion ratio；2. beam condensing unit is done using monocrystalline silicon, relatively costly and not easy-maintaining.
For above-mentioned prior art, it is still necessary to existing beam condensing unit rational modification in addition.For this reason, the applicant makees
Positive and beneficial design, and define technical scheme described below.
Content of the invention
The task of the present invention is to provide that a kind of structure is simple, low production cost, easily keep in repair and have reflector layer too
Sun can photovoltaic beam condensing unit, its small volume, can close-packed arrays and use raising solar energy conversion ratio, and can adapt to various
Adverse circumstances.
The task of the present invention is performed by, a kind of photovoltaic beam condensing unit it is characterised in that: include one
Resin-encapsulated, reflector layer, silicon chip and pin, described silicon chip is fixedly connected on the top of reflector layer short transverse, and pin is reflexive

Resin-encapsulated is fixedly connected on above reflector layer, in the encapsulation of silicon chip embedded resin.
In a specific embodiment of the present invention, described resin-encapsulated is transparent light-transmitting materials and up structure
Cheng Youyi sphere.
After the present invention adopts said structure, have the advantages that firstly, since adopting the resin-encapsulated of sphere as poly-
Bright finish, thus not only effectively increase concentration ratio and also ensure that beam condensing unit can work under various adverse circumstances；Next, by
In beam condensing unit small volume and can close-packed arrays, therefore same light according to and equal area under conversion ratio greatly improve；3rd, knot
Structure, simply it is easy to produce, is conducive to saving production cost, can meet industrialization expanding production requirement simultaneously.
