110 array of photovoltaic cell receiver.
Second, minitype reflector 130 is using high power concentrator speculum, the minitype reflector 130 small, ruler with focal length
It is very little it is small, be unlikely to deform, the advantages that precision is high, cost is relatively low, light, book is realized in high power concentrator field, short, small is set
Meter.In addition, using high power concentrator speculum, miniature compound photovoltaic cell high power concentrator power generation module group 100 can be promoted and opened a way
Voltage.
Third, the production technology of photovoltaic cell receiver 110 can be met using the technique of LED encapsulation and patch to be added
Work production requirement, production equipment can also directly use the production equipment of LED encapsulation and patch, not need particularly customized equipment.
Exemplary, the envelope of paster LED 3535,4040 or 5050 may be used in photovoltaic cell receiver 110 provided in an embodiment of the present invention
It installs standby.The miniature compound photovoltaic cell high power concentrator power generation module group 100 is using above-mentioned LED processing technologies and sets
It is standby, allow LED industry that can reduce miniature compound photovoltaic cell high power concentrator power generation with the cooperation photovoltaic industry field of diversification
The production cost of module 100.
4th, height of the embodiment of the present invention as shown in Figure 1 to miniature compound photovoltaic cell high power concentrator power generation module group 100
Degree size H is not especially limited, but it is determined according to the focal length of minitype reflector 130, exemplary, please refers to Fig. 1, this hair
The miniature compound photovoltaic cell high power concentrator power generation module group 100 that bright embodiment provides, the focal length of minitype reflector 130 are
80cm, therefore the height H of miniature compound photovoltaic cell high power concentrator power generation module group 100 is 80cm.
Fig. 1 is please referred to, miniature compound photovoltaic cell high power concentrator power generation module group 100 provided in an embodiment of the present invention makes
With in the process, minitype reflector 130 receives one group of parallel sunlight, and is reflected to photovoltaic cell receiver 110, generates electricity
Pressure and electric current, and it is introduced to positive and negative lead wires 140, output current and voltage.
5th, III-V compound refer to N, P of B, Al, Ga, In and V race of III group in the periodic table of elements, As,
The compound that Sb is formed, is miniature compound.It is excellent that the III-V compound battery has that conversion rate is fast, transformation efficiency is high etc.
Point.
Using III-V compound battery so that the base of this miniature compound photovoltaic cell high power concentrator power generation module group 100
The appearance and size of seat 120 is smaller, therefore can use universal automated production equipment, need not be fixed according to the demand of client
Control equipment reduces because of design and the manufacture increased cost of production equipment for customizing and pedestal 120 cost of raw material of itself, together
Shi Caiyong automation equipments make production capacity improve, and reduce cost of labor, and the precision of product can also reach requirement.
Since III-V compound battery form factor is smaller, the resistance value of single photovoltaic cell 111 is smaller, single
The heat that point generates is smaller, and surface temperature also can be relatively low, radiates without cooling mechanism is in addition arranged, and is reducing
Generating efficiency is influenced while the production cost of the miniature compound photovoltaic cell high power concentrator power generation module group 100 smaller.
A kind of miniature compound photovoltaic cell high power concentrator power generation module group 100 provided in an embodiment of the present invention, passes through setting
III-V compound battery makes the heat source of miniature compound photovoltaic cell high power concentrator power generation module group 100 disperse, and effectively reduces
The temperature of photovoltaic cell 111, need not be arranged cooling system, reduce miniature compound photovoltaic cell high power concentrator hair
The degree electricity cost of electric module 100；The photovoltaic cell 111 has the advantages that high conversion simultaneously, micro- by being arranged on bottom plate 122
Type speculum 130 so that the miniature compound photovoltaic cell high power concentrator power generation module group 100 can improve hair with high power concentrator
Electrical efficiency and the efficiency of light energy utilization.
Please refer to Fig. 2, the weldering for being printed with application circuit 124 on 121 lower surface of upper cover glass and being connect with application circuit 124
Point (not shown), photovoltaic cell receiver 110 are welded on solder joint.So, when encapsulating packing, in addition to
Except upper cover glass 121 and photovoltaic cell receiver 110, it is not required to extra encapsulation, it using the above structure, can be by upper cover glass 121
It is bonded and makes with photovoltaic cell receiver 110, reduce extra bonding wire.In addition, using the above structure, assembly technology is simplified,
The mistake of wiring and assembly and the probability of poor contact are greatly reduced, the gentle productive labor rate of Automated water is improved.
Further, Fig. 3 (in order to ensure that view is clear, cover glass 121 is not shown in Fig. 3), the pedestal are please referred to
120 further include frame 125, and the frame 125 connect with the upper cover glass 121 and bottom plate 122 and surrounds closing sky respectively
Between.Using the pedestal 120 of closed design so that miniature compound photovoltaic cell high power concentrator power generation module group 100 it is windproof, anti-
Dirt and rainproof function are reinforced, and photovoltaic cell receiver 110 and minitype reflector 130 are not easy due to extraneous enclosed construction
It is infected with dust, is reduced because caused by drenching with rain or making moist the phenomenon that photoelectric cell damage.
