Abstract
The utility model discloses a solar-energy photovoltaic module. The photovoltaic module comprises a glass layer, a front layer glue film, several cell sheets which are in an interval array arrangement way, a rear layer glue film and a photovoltaic back plate. The glass layer, the front layer glue film, the several cell sheets, the rear layer glue film and the photovoltaic back plate are glued successively. The photovoltaic back plate comprises a mirror surface reflection portion which is covered by the cell sheets and a diffuse reflection portion arranged in a gap of the cell sheets. By using the solar-energy photovoltaic module, a photon utilization rate and output power can be increased.
Description
Technical field
The utility model relates to a kind of solar photovoltaic assembly.
Background technology
Several cell pieces that solar photovoltaic assembly is generally arranged glassy layer, anterior layer glued membrane, spaced array by vacuum high-temperature, rear layer glued membrane, photovoltaic back are glued together, used glassy layer, forward and backward layer glued membrane and photovoltaic back all have absorption and reflex to sunlight, have reduced the conversion efficiency of photovoltaic module.And because being the interval, cell piece arranges, when solar photovoltaic assembly was worked towards the sun, the light that incides on the cell piece can use, and, the light that incides the cell piece gap does not then utilize, and has so just restricted photon utilance and the power output of photovoltaic module.
The utility model content
Technical problem to be solved in the utility model is: a kind of solar photovoltaic assembly that improves photon utilance and power output is provided.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of solar photovoltaic assembly, comprise some cell pieces, rear layer glued membrane and photovoltaic back that glassy layer, anterior layer glued membrane, spaced array are arranged, described glassy layer, anterior layer glued membrane, some cell pieces, rear layer glued membrane and photovoltaic back are glued together successively, and described photovoltaic back comprises the mirror-reflection section that is covered by cell piece and is positioned at the diffuse reflection section in cell piece gap.
As a kind of preferred scheme, the cross section of described diffuse reflection section is isosceles trapezoid, and the lower base angle of described isosceles trapezoid is 30 °.
As a kind of preferred scheme, described diffuse reflection section is sphere diffuse reflection section.
After having adopted technique scheme, effect of the present utility model is: because described photovoltaic back comprises the mirror-reflection section that is covered by cell piece and the diffuse reflection section that is positioned at the cell piece gap, therefore, light is injected from glassy layer, the light that incides on the cell piece is utilized, the light of simultaneously partial penetration cell piece is reflected by photovoltaic back and again utilizes, diffuse reflection occurs through diffuse reflection section in the light that incides the cell piece gap, like this, part light reflexes on the cell piece at this after can passing and inciding glassy layer behind the anterior layer glued membrane, so just improve the utilance of photon, improved the power output of photovoltaic module.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the light diffuse reflection schematic diagram of the utility model embodiment;
In the accompanying drawing: 1. glassy layer; 2. anterior layer glued membrane; 3. cell piece; 4. rear layer glued membrane; 5. photovoltaic back; 51. mirror-reflection section; 52. diffuse reflection section; 6. fixed border.
Embodiment
Below by specific embodiment the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of solar photovoltaic assembly, comprise some cell pieces 3, rear layer glued membrane 4 and photovoltaic back 5 that glassy layer 1, anterior layer glued membrane 2, spaced array are arranged, described glassy layer 1, anterior layer glued membrane 2, some cell pieces 3, rear layer glued membrane 4 and photovoltaic back 5 are glued together successively, the part that is fixed is sent into laminating machine, under vacuum environment, it is carried out adhesive curing, then install and fix frame 6 at the assembly equipment of framing up.Described photovoltaic back 5 comprises the mirror-reflection section 51 that is covered by cell piece 3 and the diffuse reflection section 52 that is positioned at cell piece 3 gaps.
Wherein, the cross section of described diffuse reflection section 52 is isosceles trapezoid, and the lower base angle of described isosceles trapezoid is 30 °.Certainly, described diffuse reflection section 52 is sphere diffuse reflection section 52.Its mirror-reflection section 51 is zinc-plated on the photovoltaic back 5 that is covered by cell piece 3, and becomes mirror-reflection section 51.
Solar photovoltaic assembly of the present utility model has taken full advantage of the light that is injected into cell piece 3 gaps, light is injected from anterior layer glued membrane 2 afterwards by diffuse reflection section 52, reflected by glassy layer 1 again and enter on the cell piece 3, like this, just realize the utilization maximization of light, improved the utilance of photon and the power output of photovoltaic module.
