Specific implementation mode
The illustrative embodiments of the disclosure are more fully described below with reference to accompanying drawings.Although showing this public affairs in attached drawing The illustrative embodiments opened, it being understood, however, that may be realized in various forms the disclosure without the reality that should be illustrated here The mode of applying is limited.It is to be able to be best understood from the disclosure on the contrary, providing these embodiments, and can be by this public affairs The range opened completely is communicated to those skilled in the art.
Fig. 1 shows to the flexible thin-film solar cell 100 provided Fig. 2 shows embodiment according to the present utility model It is intended to.As shown in Figure 1, the flexible thin-film solar cell 100 is applied to stratospheric airship, including base wad 2 and it is fitted in base Solar cell module 1 on the upper surface of pad 2, base wad 2 are arranged to the structure to match with solar cell module 1, until The shape of few upper surface matches.
Solar cell module 1 be configured to by multiple cell plate groups at bucking ladder array structure, be capable of providing it is multiple not With the light plane of incidence of angle, solar panel includes rectangular panel 11 and trapezoidal solar panel 12.By solar cell module 1 Shape is set as consistent with the upper surface shape of base wad 2 and is bonded the structural damage that can reduce flexible thin-film solar cell 100.
In specific implementation, the structure that at least upper surface shape matches with solar cell module 1 first is made in base wad 2 Solar cell module 1, is made the compact battery plate consistent with 2 faceted pebble size of base wad by body, then by one piece of rectangular panel 11 It is built into bucking ladder structure with four pieces of trapezoidal solar panels 12, and determines its voltage range, is mounted to the correspondence area of 2 upper surface of base wad Domain, then voltage according to demand, designs corresponding unit series and parallel structure, is finally integrated into flexible thin-film solar cell 100.Due to the bucking ladder close structure arrangement in Fig. 1, the shape of 2 upper surface of base wad is identical as solar cell module 1, in figure It is not shown.
In addition, bucking ladder array structure can ordered arrangement also random alignment, the size of each bucking ladder can be according to need It sets, the shape of four trapezoidal solar panels 12 of bucking ladder side may be the same or different.In the present embodiment, it is set as identical Trapezoid mesa-shaped array structure, can reduce the consumption of solar panel, reduce cost.
As shown in Fig. 2, using optical reflection principle, multiple inclined trapezoidal solar panels are set on the reflection path of light 12, light can be made incident from surrounding different angle, and pass through multiple reflections, reduce light reflectance, effectively improve battery and exist Light absorption under incidence angles degree improves the comprehensive property of light absorption.In view of noon irradiation intensity is maximum, numerical value is irradiated Highest ensures in high irradiation intensity so remaining the vertical radiation plane i.e. rectangular panel 11 of larger area to the sun Energy makes full use of.
In addition, the direct projection effect of particular elevation light can be also presented in inclined trapezoidal solar panel 12, realize to a certain extent To solar irradiation from motion tracking, the efficiency of light energy utilization of balanced different periods on daytime makes solar cell maintain relatively stable work( Rate exports.
The arrangement of solar cell module 1 is relatively flexible, and can be also alternatively arranged with close-packed arrays.Fig. 3 and Fig. 4 are shown The schematic diagram for the spaced flexible thin-film solar cell 100 ' that embodiment according to the present utility model provides.Such as figure Shown in 3 and Fig. 4, when the bucking ladder spacing structure that will be built by rectangular panel 11 ' and trapezoidal solar panel 12 ' arranges, in base Tiling is pasted with solar panel 13 ' between two adjacent bucking ladder structures on pad 2 ', makes full use of the strong solar irradiation at noon, increases Add order of reflection, incident light is made as close as direct projection state, to improve the efficiency of light energy utilization always.
In addition, rectangular panel 11 ', trapezoidal solar panel 12 ' and solar panel 13 ' considerably increase flexible thin-film solar The whole attachment area of battery 100 ', increases the radiating surface of solar panel, improves the performance of solar cell module 1 '.
In specific implementation, solar cell module 1 can also integrally be mounted on the upper surface of base wad 2, first by the upper of base wad 2 Surface is set as bucking ladder array structure, is then embossed into a monoblock solar panel and base wad 2 by laminating molding The identical bucking ladder array structure of upper surface shape.
The utility model can use the mode of gluing to glue flexible thin-film solar cell 100 mounted in stratospheric airship Designated position.
It should be pointed out that the weight of flexible thin-film solar cell 100 is shared in the overall weight of stratospheric airship Ratio it is relatively fewer, do not interfere with the buoyant weight balance of dirigible, change that there is no significantly affect to the torque factor of dirigible.
The preferable specific implementation mode of the above, only the utility model, but the scope of protection of the utility model is not It is confined to this, any one skilled in the art within the technical scope disclosed by the utility model, can readily occur in Change or replacement, should be covered within the scope of the utility model.Therefore, the scope of protection of the utility model should be with Subject to the scope of the claims.
