Definitions
- the present invention relates to a solar cell back surface protective sheet disposed on the back surface side of a solar cell, and more particularly to a solar cell back surface protective sheet having a function of suppressing a temperature rise of the solar cell.
- the solar cell module Since solar cells are mainly installed on the roof of buildings, heat is transmitted from the roof simultaneously with direct heating by sunlight, and the temperature of the solar cells may reach 70 ° C or higher. When the solar cell is based on crystalline silicon, the conversion efficiency is said to decrease at a rate of about 0.4% / ° C. due to the temperature rise.
- the back surface protection sheet for solar cells is generally laminated
- Patent Document 1 relates to a solar cell module heat dissipation film and a solar cell module including the heat dissipation film. Specifically, it is described that the module temperature is lowered by providing a heat-dissipating paint layer (heat dissipating film) on the back surface of the solar battery cell. In order to impart weather resistance to the paint layer, an overcoat or a weather resistant film is required, but it is necessary to select a material that does not hinder heat dissipation.
- a heat-dissipating paint layer heat dissipating film
- Patent Document 2 relates to a mist spray system. Specifically, it is described that a mist is sprayed on a solar cell module by a mist spraying system using a heat conversion paint to lower the module temperature. Note that the solar cell back surface protection sheet and the solar cell itself in Patent Document 2 do not have a function of suppressing the temperature rise.
- the heat conversion paint is a paint containing heat conversion molecules having a function of consuming heat energy by converting heat energy into vibration energy.
- This paint is sold, for example, as product name “Tough Coat D42, D47” by Albert Kogyo Co., Ltd., and is generally called a heat-dissipating paint.
- An object of the present invention is to provide a back protective sheet for a solar battery having a function of suppressing a temperature rise of the solar battery cell.
- the present inventor has found that the above object can be achieved when using a solar cell back surface protective sheet having a specific heat conversion layer, and completes the present invention. It came.
- this invention relates to the following back surface protection sheet for solar cells.
- a solar cell back surface protection sheet disposed on the back surface side of the solar battery cell, It has a heat conversion layer containing a heat conversion filler having a function of consuming heat energy by converting heat energy into vibration energy, and the density of the heat conversion filler in the heat conversion layer is 3 to 35 g / m 2
- the back surface protection sheet for solar cells characterized by being.
- Item 2 The back protective sheet for a solar cell according to Item 1, wherein the solar cell back surface protective sheet has a resin film substrate, and the heat conversion layer is formed on one surface or both surfaces of the resin film substrate. 3.
- the solar cell back surface protective sheet according to Item 1 which is formed. 4).
- Item 4. The back protective sheet for solar cells according to any one of Items 1 to 3, wherein the heat conversion layer is formed by applying and drying a paint containing the heat conversion filler. 5.
- Item 5. The back protective sheet for a solar cell according to any one of Items 1 to 4, wherein the heat-sealing layer contains a component that can be heat-sealed with an ethylene-vinyl acetate copolymer.
- the back surface protection sheet for solar cells of the present invention is a back surface protection sheet for solar cells disposed on the back surface side of the solar cells, It has a heat conversion layer containing a heat conversion filler having a function of consuming heat energy by converting heat energy into vibration energy, and the density of the heat conversion filler in the heat conversion layer is 3 to 35 g / m 2 It is characterized by being.
- the solar cell back surface protective sheet of the present invention having the above characteristics can suppress an increase in the temperature of the solar battery cell because the heat conversion filler in the heat conversion layer converts the heat energy into vibration energy and consumes it. It is desirable to form the outermost layer if it is a coating that suppresses temperature rise using reflection or radiation of thermal energy, but if it is a heat conversion layer used in the present invention, it consumes thermal energy even if it is not the outermost layer. Therefore, the heat conversion layer can be formed as an inner layer (a layer not exposed on the surface).

- a base material As a base material, it is possible to improve the thermal conductivity by using a metal foil such as an aluminum foil and amplify the heat conversion effect. It is necessary to open a hole for taking out the electrode wire, and if the back surface protection sheet for solar cells contains metals, the solar cells may be short-circuited if insulation treatment is insufficient. It is preferable to use a resin film substrate as in the invention. However, when the insulation treatment can be sufficiently performed, a metal foil such as an aluminum foil can be used in combination with the resin film base as necessary.
- the thickness of the resin film substrate is not limited, but is preferably 200 to 300 ⁇ m, more preferably 100 to 250 ⁇ m.
- the withstand voltage as the back surface protection sheet for solar cells is low, and when it is too thick, the weight as the back surface protection sheet for solar cells increases and adheres to the back surface of the solar cells. This is because there is a possibility of peeling from the solar battery cell with long-term use.

- the type and thickness of the adhesive can be appropriately set according to the type of each layer to be bonded.
- Thermal conversion layer contains a thermal conversion filler (thermal conversion molecule) having a function of consuming thermal energy by converting thermal energy into vibration energy. Infrared rays contained in sunlight etc. are converted into thermal energy when propagating to the heat conversion layer and dispersed and moved in the heat conversion layer, but vibration energy is immediately converted by contacting the heat conversion filler in the heat conversion layer. Since this energy conversion occurs on the surface layer of the heat conversion filler, most of the heat energy is quickly consumed. Therefore, heat energy is consumed without accumulating in the heat conversion layer. Moreover, in this invention, the withstand voltage property of the back surface protection sheet for solar cells can also be improved by forming a heat converting layer.

- the above-mentioned paint is referred to as a so-called heat conversion paint (heat-extinguishing paint), and is sold, for example, as a product name “Tough Coat D42, D47” by Albert Kogyo Co., Ltd.
- the “Tough Coat D42” is a two-component curable heat conversion paint containing an acrylic polyol resin and a heat conversion filler as main components and isocyanate (HMDI: hexamethylene diisocyanate) as a curing agent.
- “Tough Coat D47” is an aqueous one-component curable heat conversion paint containing a styrene-acrylate copolymer resin, a thermoplastic urethane resin, and a heat conversion filler.

If the thickness is less than 10 ⁇ m, the heat conversion efficiency is poor, and if it exceeds 200 ⁇ m, the improvement of the heat conversion efficiency commensurate with the film thickness cannot be obtained.
- the heat conversion layer may be provided on one side or both sides of the resin film substrate, and when provided on both sides, the heat conversion layer should be divided into two layers so that the total thickness is in the above range. Is preferred.

It is desirable to form the outermost layer if it is a coating that suppresses temperature rise using reflection or radiation of thermal energy, but if it is a heat conversion layer used in the present invention, it consumes thermal energy even if it is not the outermost layer. Therefore, the heat conversion layer can be formed as an inner layer (a layer not exposed on the surface).
