Description
Technical field
The invention belongs to application of solar, specifically, is a kind of line style concentrating solar photovoltaic generating module with Fresnel cylindrical lens.
Background technology
Solar photocell is a kind of junction type photoelectric device that can be directly changed into luminous energy electric energy, the generating pattern that with the solar photocell is electrooptical device has simple in structure, reliability is higher, characteristics such as the life-span is long, worldwide have fast development trend, become the inexhaustible clean energy resource of a kind of mankind.
At present, application number is that 2008100420905 Chinese patent application discloses a kind of concentrating solar photovoltaic generating module, its formation is: polylith square solar photocell, heating panel is equipped with at the back side of every solar photocell, every block of heating panel independently is installed on the base plate, and arranges in a certain order.Point focusing type Fresnel Lenses is housed directly over the every solar photocell, the material of Fresnel Lenses is the good macromolecular material of light transmission, Fresnel Lenses is installed on the framework, and its effect is that solar energy directly is focused on the pairing solar photoelectric pool surface.Every solar photocell is connected by Copper Foil, and every solar photocell receives the luminous energy gathering-device that a stainless sheet steel inverted pyramid formula, that four inner surfaces are minute surface also has been installed between the surface of luminous energy and the Fresnel Lenses, its effect: the one, solve the prior art electricity generation module and follow the tracks of the sun and assembly precision error, the solar facula that is caused departs from the photocell cosmetic issue; The 2nd, partial reflection and spuious luminous energy are projected the surface of solar photocell, thereby improve solar energy utilization rate.Yet their weak point also is that significantly the space between the square solar photocell assembly can not make full use of, and has limited the increase of solar photoelectric pool area, and this module energy output also can not increase; Solar photocell and heating panel have constituted stand-alone assembly, and radiating effect is bad, can descend to some extent in the photronic performance of hot weather especially; The quantity of Copper Foil is more, and the gathering-device manufacture craft of solar energy is comparatively complicated, and production cost is higher.
Summary of the invention
The purpose of this invention is to provide a kind of solar photoelectric pool area big, can make more solar-energy collecting on solar photocell, to increase the energy output of module, improve the concentrating solar photovoltaic generating module with Fresnel cylindrical lens of generating efficiency.
Concentrating solar photovoltaic generating module with Fresnel cylindrical lens of the present invention comprises the polylith solar photocell, is installed in the heating panel at the every solar photocell back side, and the front of every solar photocell has corresponding with it Fresnel cylindrical lens; Connect with Copper Foil between the solar photocell; Solar photocell is bar shaped, and Fresnel cylindrical lens is the line focus type Fresnel cylindrical lens that is rectangle.
Beneficial effect of the present invention: corresponding with it rectangle Fresnel cylindrical lens is housed directly over the bar shaped solar photocell, and Fresnel cylindrical lens forms the effect of strip hot spot on the bar shaped solar photocell when receiving solar energy.The present invention is with respect to prior art, because the line focus type Fresnel cylindrical lens that has adopted the bar shaped solar photocell and be rectangle, if photovoltaic generating module is under the measure-alike prerequisite of profile, increased the area of solar photocell, the present invention can make more photon converge on the solar photocell through Fresnel cylindrical lens, and solar photocell can be converted into electric energy to more luminous energy.And the solar photocell square that prior art adopts, be independently between the photocell, photronic position more than 4 is set having between two photocells, obviously the optical characteristics of prior art has determined these positions not have illumination, and the present invention adopts the rectangular line focus type Fresnel cylindrical lens and the bar shaped solar photocell that form the strip hot spot to address this problem.In addition, the present invention adopts line focus type Fresnel cylindrical lens, with respect to the Fresnel Lenses of existing point focusing type, and the easier shortening of focal length.Because point focusing type Fresnel Lenses focal length shortens, the size of the lip-deep hot spot four direction of solar photocell can reduce; Line focus type Fresnel cylindrical lens focal length shortens, and the size of two directions of hot spot can reduce.If the area that two kinds of Fresnel Lenses are accepted luminous energy is identical, obviously the focal length of the two shortens simultaneously and equates, the electricity generation module energy output that the point focusing type constitutes reduces more than the electricity generation module that the line focus type constitutes.The beneficial effect that focal length shortens is that solar photocell can be littler to the distance of Fresnel cylindrical lens, can reduce the height of electricity generation module, reduces the electricity generation module volume, helps module to miniaturization, the automation direction development.The 3rd, the bar shaped solar photocell is compared with existing technology has increased area, has only between the bar shaped solar photocell just to connect with Copper Foil, with respect to prior art, has significantly reduced the quantity of Copper Foil, has reduced production cost.
Above-mentioned photovoltaic generating module has the cooling water pipe to its cooling in heating panel.During use, cooling water pipe is by cooling water, so that heating panel is cooled off.The performance of solar photocell at high temperature changes easily, and lattice structure can be damaged.Because bar shaped solar photoelectric pool area is bigger, the cooling water that flows in the cooling water pipe reaches the purpose of the heat radiation of quickening solar photocell in the summer of sweltering heat, guarantees its operate as normal.
Above-mentioned photovoltaic generating module, after Fresnel cylindrical lens receives the solar energy of normal incidence, the width that forms the strip hot spot should be less than the width of solar photocell, so both made the tracking accuracy of electricity generation module and the misalignment solar photocell center that rigging error causes the strip hot spot, hot spot still can be distributed in the solar photoelectric pool surface.
Above-mentioned photovoltaic generating module is equipped with two mirror boards in the both sides of solar photocell and the Fresnel cylindrical lens corresponding with it, constitutes the little light groove in the big end, top, and the less bottom of light groove is connected the both sides of solar photocell.Sunlight focuses on the solar photocell by Fresnel cylindrical lens, and skew originally is according to less than the sunlight on the solar photocell, gathers on the solar photocell again under the reflection of the mirror board of light groove, thereby has increased energy output.This light groove is simpler as the structure of luminous energy gathering-device, thereby production process is simplified, and is convenient to install.
Above-mentioned photovoltaic generating module, Copper Foil is bending, for Copper Foil provides surplus when expanding with heat and contract with cold; Avoid Copper Foil fracture or come off.
Above-mentioned photovoltaic generating module, it also comprises ultrawhite toughened glass, Fresnel cylindrical lens is arranged the back side that sticks on ultrawhite toughened glass.Preferably ultrawhite toughened glass is installed on the framework of electricity generation module, and framework is installed on the base plate, and the rectangle heating panel is installed on the base plate.Because Fresnel cylindrical lens sticks on the ultrawhite toughened glass matrix, and is enclosed in the inside of electricity generation module, avoids directly contacting with nature, has prolonged the useful life of devices such as Fresnel cylindrical lens and solar photocell.
