In the solar charging device 100 according to embodiment of the present utility model, total face of multiple solar cells 20
The very small part of the long-pending area for only occupying flexible PCB 10, such as 5%-30%, preferably approximately 10%.Non-solar cell batteries
Working region occupies most of area of flexible PCB 10, such as about 90%.So these non-solar cell batteries pieces work
Region is impaired to be had an impact to the normal power generation of solar battery sheet.And in traditional solar charging device, solar energy
Battery is usually all standing formula, occupies the entire area of solar charging device substantially, therefore the impaired meeting of a part of battery is big
The big generating efficiency for reducing solar battery sheet, more serious possibility cause solar charging device directly to be scrapped.According to this reality
Discrete micro cell piece is used with the solar charging device of new embodiment, such structure is improving solar energy generating efficiency
While can also greatly improve the reliability of solar charging device.
Fig. 2 a are the parameter schematic diagrames of the collector lens in the film type solar charging device 100 shown in Fig. 1, and Fig. 2 b are
The schematic diagram of the critical angle of incidence of Fig. 2 a shown collector lens.Lens 31 and battery 20 are schematically illustrated in figure.Optically focused
The photoelectric transformation efficiency of solar cell is relevant with focusing ratio.Focusing ratio is defined as the incident aperture area and outgoing bore of optically focused
Ratio of the area of area ratio, i.e. lens than the light-receiving area of upper battery.
As shown in Figure 2 a, r is that (outgoing bore is circular for outgoing bore if circle, r for the 1/2 square length of side of outgoing bore
Radius), R is square 1/2 length of side of incident bore (for outgoing bore if circle, R is the circular radius of incident bore), and f is
The focal length of lens.Cell piece 20 is placed in the lower section of lens 31, and spacing is h therebetween.
It is for 2D solar concentrator geometric concentrating ratios：
C=S1/S2=r2/R2
In above formula：S1To be emitted aperture area, S2For incident aperture area, r is that the 1/2 square length of side of outgoing bore (goes out
If circle, r is to be emitted the circular radius of bore in loophole footpath) (outgoing bore is if circle for the 1/2 square length of side of incident bore by R
Shape, R are the circular radius of incident bore).
Schematic diagram to be defined according to the critical angle of incidence of one embodiment of the present utility model as shown in Figure 2 b.Such as Fig. 2 b
It is shown, define critical angle of incidence θ so that battery surface is not just arrived with the light that critical angle of incidence θ is incident.
In formula：C is geometric concentrating ratio, and f is the focal length of lens.
According to one embodiment, geometry light concentrating times are set as 8 times, and the size of design low power lens 31 is 4mm × 4mm, micro-
The size of cell piece 20 is 1.4mm × 1.4mm, and focal length of lens f is 4mm, and the thickness h of soft light film 32 is 2.6mm.Critical angle of incidence
θ=29 °.When incidence angle is less than 29 ° of critical angle, the surface that light low power converges to cell piece is just had.
Embodiment of the present utility model uses low-concentration, it is not necessary to is equipped with solar-tracking system so that diaphragm type is too
Positive energy charging device small volume, it is in light weight.Big incident angle as far as possible more can use in reality largely scattering light
Produce electric energy, this improves capacity usage ratio, add caused by electric energy amount.Relatively low light concentrating times, can also be significantly
The temperature of solar battery sheet is reduced, avoids high-temperature damage.It is critical to expand it is of course possible to select smaller spacing h (h≤f)
Incidence angle, but light concentrating times can diminish geometry multiple, while the area of cell piece can become big significantly, increase cost.Simultaneously
Bigger spacing h (h≤f) can be selected to increase geometric concentrating ratio, but can be raised significantly with the raising of geometric concentrating ratio
The temperature of solar battery sheet, high-temperature damage is caused to cell piece.
In an example embodiment of the present utility model, critical angle of incidence is used as 29 °, and field sweep angle is 58 °, geometry
Focusing ratio is 8, PUA lens sizes 4mm × 4mm, and the thickness of flexible transparent film 2 is 2.6mm, and miniature sheet battery size is 1.4mm
×1.4mm.Light of the incidence angle within 29 ° can effectively gather cell piece surface, it is not necessary to be equipped with sunshine and chase after
Track system.Big incident angle, which can also be used as often as possible, largely scatters light to produce electric energy in reality, therefore, improve
Capacity usage ratio, add caused by electric energy amount.In addition, relatively low light concentrating times, can substantially reduce solar cell
Temperature, avoid high-temperature damage.It is of course possible to select bigger incidence angle, but light concentrating times meeting geometry multiple diminishes.When entering
When firing angle is 70 °, geometry light concentrating times are only 1.85 times, and now light concentrating times are low and need the cell piece (2.94mm of large area
× 2.94mm), the increase of battery manufacture cost.The solar charging device of the utility model embodiment can be in the feelings of low-concentration
Used under condition, the light of incidence angle within limits can produce electric energy by battery absorption.For example, incidence angle can be with
Between 0 °~29 °.
Using low-concentration rather than high power concentrator, many advantages are brought.High power concentrator is very harsh to optical design requirements,
Very high is required to incident angle, it is necessary to sunshine tracing system is equipped with, and volume is big, and weight is big.Implementation of the present utility model
Low-concentration is used in example, relaxes requirement of the optically focused to incident angle significantly, it is not necessary to bulky sunshine tracing system, i.e.,
In the case of making light poor, charging device can also be charged.
According to an example, critical angle of incidence is used as 29 °, and field sweep angle is 58 °, and geometry light concentrating times are 8 times, low power
The size of PUA (urethane acrylate) lens is 4mm × 4mm, focal length 4mm, and the thickness of flexible transparent film 2 is 2.6mm, micro- electricity
Pond chip size is 1.4mm × 1.4mm.Flexible circuit plate suqare 10cm × 10cm, 400 lens and 400 three knots can be placed too
Positive energy battery, the output voltage of each battery 20 is in 3V or so, and it is one group that 10 batteries, which are connected, and 40 groups in parallel, can be opened a way
Voltage 30V, current density 12.6mA/cm2, short circuit current 0.08A, power output about 1.9W.
