Abstract
The utility model relates to a low-reflection photovoltaic assembly, which comprises glass at the obverse side, a solar cell group and glass at the reverse side, wherein the components are connected through EVA. The low-reflection photovoltaic assembly further comprises an anti-reflection film, wherein the anti-reflection film is connected to the surface of the glass at the obverse side through the EVA, and the anti-reflection film is an ultra-wide band porous silicon dioxide anti-reflection film with a gradient refractive index structure. The low-reflection photovoltaic assembly is designed according to characteristics of low reflectivity, high output power and self cleaning. When incident light gets into the anti-reflection film, all sunlight reaches the glass surface directly through the anti-reflection film, and the light conversion efficiency of the assembly is improved compared with a solar assembly without a coating film. In addition, an anti-reflection film layer has good self-cleaning performance, reduces the cost of daily maintenance and cleaning for the photovoltaic assembly while reducing a heat spot effect, and greatly improves the cost-performance ratio of the photovoltaic assembly.
Description
Technical field
The utility model relates to solar power generation, relates in particular to a kind of low light reflectivity photovoltaic assembly.
Background technology
New forms of energy are one of five large technical fields that in 21st century development of world economy, tool determines power.Solar energy is a kind of clean, new forms of energy of exhaustion efficiently and never, have safe and reliable, noiseless, pollution-free, restriction less, the advantage such as failure rate is low, easy maintenance.But solar energy is as the low-density energy, and energy utilization rate is low, the conversion efficiency that therefore how to improve solar energy power generating is the study hotspot problem of industry always.
Conventional photovoltaic assembly is once comprised of ultra-clear glasses, EVA, cell piece, EVA, TPT structure from top to bottom, through development for many years, the conversion efficiency of photovoltaic cell itself has been raised to the relative limit, and the transmitance that therefore improves the surface encapsulation glass of photovoltaic module becomes the effective technical way that improves photovoltaic module transformation efficiency already.At present for coated glass, have more deep research abroad, moral dip coating that solar energy research adopts was prepared solar energy glass porousness SiO such as 2004
2antireflective film; After Germany Centra-Solar company adopts and first films, tempering technology is prepared coated glass, makes its assembly energy output increase 2%-3%, and Japanese AGC adopts spraying process to prepare solar energy porousness SiO
2antireflective coating first film after the technology path of tempering, its up-to-date product normal incidence transmitance of filming can increase by 2.5%.
Utility model content
The purpose of this utility model, exactly in order to address the above problem, provides a kind of novel low light reflectivity photovoltaic assembly.
In order to achieve the above object, the utility model has adopted following technical scheme: a kind of low light reflectivity photovoltaic assembly, comprise face glass, solar battery group and back side glass that order arranges, and between each element, by EVA, connect; Be characterized in: also comprise antireflective coating, this antireflective coating is bonded in face glass surface by EVA, and this antireflective coating is that the ultra broadband porous silicon dioxide antireflective with graded index structure is penetrated film.
Described face glass and back side glass are low iron toughened glass.
Described solar battery group is lined up display by the cell sheet of 60 156mm * 156mm and is formed.
Low light reflectivity photovoltaic assembly of the present utility model is a kind of photovoltaic cell component with high-quality antiradar reflectivity high-conversion rate, this assembly adopts coated glass to replace traditional ultra-clear glasses, the glass of rete silicon dioxide has high stability, high transmission rate and high self-cleaning performance, in coating liquid formula, introduce a certain amount of high temperature resistant hydrophilic structure material, keep the high efficiency of rete and make rete there is Superhydrophilic feature, adopt advanced spraying technology, according to the principle of reciprocal spraying, 2 of employing now, the spraying coating process of spray gun is developed into 4-5 the spraying coating process of spray gun, research and development production has the ultra broadband porous silicon dioxide antireflective of graded index structure and penetrates rete, domestic unique spraying production technology at present, the optical match of research glass antireflective coating, photovoltaic component encapsulating material, is mainly reflected in the spectral-transmission favtor of coated glass/EVA/SiNX composite bed and the matching of solar spectrum, realizes the combination of coated glass and photovoltaic power generation technology.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of low light reflectivity photovoltaic assembly;
Fig. 2 is the front view of low light reflectivity photovoltaic assembly;
Fig. 3 is the rear view of low light reflectivity photovoltaic assembly.
Embodiment
Referring to Fig. 1, coordinate referring to Fig. 2, Fig. 3, the utility model low light reflectivity photovoltaic assembly, comprises antireflective coating 1, face glass 2, solar battery group 3 and back side glass 4 that order arranges, between each element, by EVA5, connects.
Antireflective coating 1 in the utility model is penetrated film for having the ultra broadband porous silicon dioxide antireflective of graded index structure.
Face glass 2 in the utility model and back side glass 4 are low iron toughened glass.
Solar battery group 3 in the utility model is lined up display by the cell sheet of 60 156mm * 156mm and is formed.
As mentioned above, low light reflectivity photovoltaic assembly of the present utility model, for antiradar reflectivity high transmission rate feature, design, when incident ray penetrates antireflective coating and is incident upon glass interface, the reflectivity of sunlight is almost 0 (without plated film time, the reflectivity of sunlight is about 4%), sunlight enters after glass medium, glass is about 1-2% to the absorptivity of sunlight, and then light is incident upon cell piece by glass medium, photovoltaic cell component efficiency can be improved to 2% left and right.The hydrophily of coated surface material causes and makes it have good self-cleaning performance in addition, has reduced to a certain extent situation that hot plate effect occurs and the accumulation of dust, further improved photovoltaic module Efficiency Decreasing the maintenance cost of photovoltaic module.
