Abstract
The invention relates to a solar cell, especially to a transparent conducting glass substrate with an antireflection coating for a thin film solar cell, which is utilized to produce solar cell packs. The transparent conducting glass substrate comprises an ultra-white float glass panel (1), a transparent conducting coating (2) coated on the surface of one side of the ultra-white float glass panel (1), and a ray antireflection coating (3) coated on the surface of the other side of the ultra-white float glass panel (1). The invention has the advantages that (1) the light transmittance and the power increment are higher, wherein the transparent conducting glass substrate is provided with the ray antireflection coating to greatly increase the light transmittance, and the light transmittance is increased by 2% to 3%; the light absorptivity of a photo-electricity conversion layer is also increased to ensure that the output power of solar cell packs is increased; and (2) the cost performance is high and the use cost is low. In the invention, the production cost is slightly increased, but the performance is greatly improved.
Description
Technical field
The present invention relates to a kind of solar cell, particularly a kind of thin-film solar cells transparent conducting glass substrate with antireflection coatings is used for the manufacturing of solar module.
Background technology
Solar cell has obtained using widely at present, and as the cleaning new energy of a kind of green, environmental protection, solar cell has wide development space.The substrate that all needs a film to adhere in the existing thin-film solar cells manufacturing, this substrate must be conducted electricity, and could make the film of various materials on this again, forms various thin-film solar cells.And this base material can be hard glass, stainless steel or flexible plastic sheets.General use sheet glass and plastics all need coated with conductive coating in the above when doing substrate.Conductive coating must be transparent, so conductive coating also claims transparent conducting coating, and sunlight sees through glass and conductive coating shines on the opto-electronic conversion coating of thin-film solar cells.But when using ultra-white float glass as base material, because sheet glass itself has sorption to light, there is reflex action on two surfaces of sheet glass for light, make the transmittance of sunlight generally be no more than 91.5%, cause the sunlight about 8.5% not obtain yet utilizing, this sunlight of about 8.5% also is the very huge energy, and this causes the reduction of solar conversion efficiency, and use cost increases.Improve the utilization ratio of about 8.5% sunlights that do not obtain utilizing, be an insurmountable technical barrier always.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, the thin-film solar cells transparent conducting glass substrate with antireflection coatings that a kind of light transmission power increasing amount higher, that can make solar components is higher, use cost is low is provided.
The technical scheme that realizes above-mentioned purpose is: a kind of thin-film solar cells transparent conducting glass substrate with antireflection coatings, comprise the ultra-white float glass plate, also include the transparent conducting coating that is arranged on ultra-white float glass plate one side surface, the opposite side surface of ultra-white float glass plate is provided with the light antireflection coatings.
Further, described light antireflection coatings is at least one deck, and the light antireflection coatings of outermost one deck is a porous silica layer in the light antireflection coatings.
Further, described transparent conducting coating material is a tindioxide.
Adopt technical scheme of the present invention, have the following advantages: (1) transmittance and power increasing amount are higher.The present invention improves innovation to the ultra-white float glass plate that transparent conducting coating is set on the existing side surface, on the opposite side surface of ultra-white float glass plate the light antireflection coatings is set.Because the present invention has the light antireflection coatings, and transmittance of the present invention is increased greatly, transmittance improves 2%～3%, and light transmission is higher, and meanwhile the absorptivity of photoelectric conversion layer is also being followed increases, and makes the output rating of solar module increase; (2) cost performance height, use cost is low.The present invention is owing to have the light antireflection coatings, and it is few that cost of manufacture increases, but performance of the present invention is improved greatly, thereby the cost performance height, and use cost reduces greatly.

Embodiment two
As shown in drawings, present embodiment and embodiment one are basic identical, different is that light antireflection coatings 3 is for two-layer, the light antireflection coatings 3-1 of outermost one deck is a porous silica layer in the light antireflection coatings 3, other light antireflection coatings 3-2 is the general silica layer, and the light antireflection coatings 3-1 of outermost one deck refers in the light antireflection coatings 3 is exactly that one deck towards sunlight incident direction A.The thickness of porous silica layer is 120nm, and the square resistance of transparent conducting coating is 10 Ω/, and transmittance is 83%, mist degree 8%.
When the present invention makes, on ultra-white float glass plate 1, apply polished yarn antireflection coatings 3 earlier, handle according to processing sequence, finish after 3 making of light antireflection coatings, the technology according to transparent conducting coating 2 applies transparent conducting coating 2 on ultra-white float glass plate 1 again.The concrete parameter of each coating can be according to user's specific requirement adjustment.
In addition to the implementation, transparent conducting coating 2 materials can also select tindioxide to mix the compound coating that the back is formed with other functional materials.Light antireflection coatings 3 also can be elected multilayers such as three layers, five layers as required as.
Embodiments of the invention are a lot, can't be exhaustive, and the technical scheme that all employings are equal to replacement or equivalence replacement formation all belongs to the claimed scope of invention.
