Description
Technical field
The present invention is relevant for a kind of modular construction and implementation method thereof of light collection system; Be meant a kind of means of package assembly modularization composite design of the light collection system that is applied in solar battery module (photovoltaic module) or solar conversion mechanism especially.
Background technology
Application Optics lens (for example Fresnel lens) and solar battery module or wafer combination come a large amount of light collection system or light-collecting modules of collecting incident light, have been existing skill.Existing light collection system comprises optical lens or element, aluminum base, optics cover plate, and a framework is arranged between aluminum base and the optics cover plate, with the kenel of said modules fixed combination.For example; US 2009/0126794A1 " Photovoltaic Concentrator Module With Multifunction Frame ", US 2009/0199890 " Solar Cell Receiver For Concentrated Photovoltaic System For III-V Semiconductor Solar Cell ", and US 2009/0223555 " High Efficiency Concentrating Photovoltaic Module Method And Apparatus " patent case etc. provide typical embodiment.
Just as those people that have the knack of this skill know, the light collection system or the module of combination such as above-mentioned use aluminum base, framework kenel all have the accumulated error of processing and height; Described accumulated error usually can be greater than the tolerable error of optics, and influences greatly or reduced the conversion usefulness of light collection system and the stability of generating efficiency.
Above-mentioned accumulated error comprises: assembled height sum of errors assembling parallelism error.The assembled height error can cause " can accept the reduction at angle "; The assembling parallelism error is caused by the not parallel institute of contraposition between this optics cover plate or optical surface and the aluminum base (or being configured in the wafer on the base plate), can cause " can accept the asymmetry at angle ".Basically, do not having under the ideal state of error, sunray can 100% incident light collection system (or wafer).But, when above-mentioned assembly error or mismachining tolerance force the incident angle of light deviation,, then be defined as and can accept the angle if collection efficiency is 90% o'clock an incident angle deviation.In general, the angle accepted of Fresnel module is about about ± 0.5 degree.For example, in existing skill, the assembled height accumulated error of parts such as optics cover plate, wafer, tin cream, copper base, thermal grease, aluminium base and framework reaches approximately ± 790 μ m (± 79 of pacts) about.When the about 500 μ m of accumulated error (about 50), the angle accepted of light collection system can only be tolerated the angular deviation of 0.3 degree approximately; Change speech,, will have the light 10% or more to overflow, can't be collected, cause the situation of optical performance reduction by light collection system or wafer if angle of incidence of light degree deviation surpasses 0.3 degree.Same, suppose not to be parallel to each other fully accurately between the assembling of optical surface and aluminium base, and when the inclination of 0.23 degree is arranged approximately, this can accept the angle only surplus 0.25～0.27 spend about.
Simultaneously; The assembling accumulated error of these light-collecting modules also can make the incident of sunray or the non-central zone that light path drops on wafer (or battery module); Make the wafer regional area produce the situation that thermal stress is concentrated, this can reduce the useful life of wafer, and that this situation is not for we is desired.
In order to improve the accumulated error problem in the above-mentioned light-collecting module assembling; Be to use base material (or high-flatness base material) that sun tracking system, high accuracy make and the instrument and equipment of costliness carries out contraposition on the practice, make in the scope that is controlled at 500 μ m that the accumulated error of its assembling can try one's best.But, the apprehensible manufacturing cost that is this situation can make base material and instrument and equipment derive rolls up.
Representational, these references have shown that relevant light source and optical module or light collection system are engaged in the skill of application facet; They also reflect these optical modules or light collecting device design in the situation of some application, more existing problems.If the institutional framework of overline design consideration light-collecting module makes its structure be different from the person of commonly using, can change its use kenel, and be different from old law; In fact, also can increase its range of application.But, how overcome or improve the above-mentioned problem that we are discussed? For example, its package assembly design is being met under the simple condition, reduce the degree of difficulty of module assembling, with minimizing equipment and human cost; Possess the accumulated error that makes the light collection system assembling simultaneously and reduced to minimum as much as possible, and further increase the conversion usefulness of light collection system and the effects such as stability of generating efficiency, improve existing structure and be unfavorable for means persons such as disassembly and assembly or indivedual displacements; We find that its structure must consider following several design problem:
1. tackling the problem of whole cooperation optics cover plate or structure organizations relevant " accumulated error of assembling " such as optical surface, board unit and framework considers.
2. in order to obtain to reduce the effect of " accumulated error of assembling ", the internal structure of this optical texture assembly and light collection system and number of assembling steps should be again by arrangement with design, just can make the loss of the incident ray sunray of wafer (or incide), be reduced to minimum.
3. compared to old law; More satisfactory design should consider manufacturing, assembling easily, allow that the operator changes the outfit individually to optical module or condition such as displacement; And the base material of using the high accuracy manufacturing as old law carries out situations such as contraposition with expensive instrument and equipment; Should be reduced as much as possible, with reduction equipment and human cost.
And these problems in above-mentioned reference all not by teaching or concrete the exposure.
