Description
본 발명은 태양전지용 접착시트 조성물, 이를 이용한 태양전지용 접착시트 및 태양전지에 관한 것이다. The present invention relates to a solar cell adhesive sheet composition, a solar cell adhesive sheet and a solar cell using the same.
근래의 환경 문제가 높아짐에 따라 크린 에너지로서 수력 발전, 풍력 발전 및 태양광 발전이 각광을 받고 있다. 그 중에서도 태양 에너지를 이용한 태양광 발전은 최근 청정하고 지구 온난화 방지에 유용한 에너지원으로서 조금씩 성장하고 있다. 이 태양광 발전의 대표로서, 단결정 실리콘, 다결정 실리콘, 아모퍼스 실리콘 등의 반도체를 사용한 태양전지를 들 수 있다. 태양전지는 반도체에 태양광이 조사되면 전류를 방출시키는 원리를 실용화한 것이다. As environmental problems increase in recent years, hydro power, wind power, and solar power have come into the spotlight as clean energy. Among them, solar power generation using solar energy is growing in recent years as an energy source that is clean and useful for preventing global warming. As a representative of this photovoltaic power generation, a solar cell using semiconductors such as monocrystalline silicon, polycrystalline silicon, amorphous silicon and the like can be given. The solar cell is a practical use of the principle that emits a current when sunlight is irradiated to the semiconductor.
또한 태양전지는 일반적으로 실리콘, 갈륨-비소, 구리-인듐-셀렌 등의 태양전지 소자를 상부 투명 보호재와 하부 기판 보호재로 보호하고, 태양전지 소자 와 보호재를 접착시트로 고정하여 제조 하는 것이다. In addition, a solar cell is generally manufactured by protecting a solar cell device such as silicon, gallium arsenide, copper-indium selenium with an upper transparent protective material and a lower substrate protective material, and fixing the solar cell device and the protective material with an adhesive sheet.
이때 태양전지 모듈에 사용되는 접착시트는 두가지 타입으로 개발되고 있다. 그 중 하나는 표준경화(standard-cure) 타입이고, 다른 하나는 속경화(fast-cure) 타입이다.At this time, the adhesive sheet used in the solar cell module is being developed in two types. One is of standard-cure type and the other is of fast-cure type.
상기 표준경화(standard-cure) 타입의 접착시트는 태양전지 모듈 합착 공정시 130℃에서 6분정도의 진공 공정, 130℃ 1분정도의 프레스 공정, 150℃ 오븐에서 40분 경화 공정순으로 합착 공정이 진행되고 있다. 여기서 온도 및 시간은 각 모듈 업체별로 차이가 다소 있지만 합착 공정 순서는 동일하다. The standard-cure adhesive sheet has a bonding process in the order of a vacuum process at 130 ° C. for 6 minutes, a press process at 130 ° C. for 1 minute, and a 40 minute curing process at 150 ° C. in a solar cell module bonding process. It's going on. Here, temperature and time vary slightly between module makers, but the order of joining process is the same.
상기 표준경화(Standard-cure) 타입의 접착시트를 사용하는 경우에는 태양전지 모듈 제조시 공정 시간이 길어 태양전지 모듈 생산량이 떨어지는 문제점을 지니고 있으며, 150℃ 오븐에서 40분 경화 공정이 진행됨에 따라 태양전지 소자의 산화가 급격히 진행되어 태양전지 제조 후 발전 효율이 떨어지는 문제점들이 보고되고 있다. In the case of using the standard-cure type adhesive sheet, the solar cell module has a problem in that the production time of the solar cell module is long due to a long process time, and as the curing process proceeds for 40 minutes in an oven at 150 ° C., The rapid progress of oxidation of the cell device has been reported problems of power generation efficiency after solar cell manufacturing.
상기 속경화(fast-cure) 타입의 접착시트는 태양전지 모듈 합착 공정시 150℃에서 3분정도의 진공 공정, 150℃ 5분정도의 프레스 공정만으로 경화공정을 대체할 수 있는 장점을 지니고 있다. 하지만 합착 공정 중 접착시트의 수축률이 커서 경화 과정 중 실리콘 발전소자의 충격을 줘서 미세크랙을 발생시킬 수 있는 문제점이 있다. 그 원인은 실리콘 발전소자의 셀 두께가 과거에는 200 um 이상 제조 되었지만 최근에는 실리콘 원자재의 부족현상 및 재료비 절감차원에서 200 um 이하로 제조하고 있기 때문이다. 또한 경화 전 접착시트 보다 경화 후 접착시트의 체적저 항이 떨어져 태양전지 모듈 효율이 떨어지는 문제점과 합착 공정중 접착시트의 아웃가스 및 기포발생으로 인하여 태양전지의 불량을 일으키는 문제점들이 보고 되고 있다. The fast-cure adhesive sheet has an advantage of replacing the curing process by only a vacuum process of about 150 minutes at 150 ° C. and a press process of about 150 ° C. for 5 minutes during the solar cell module bonding process. However, the shrinkage rate of the adhesive sheet during the bonding process is large, there is a problem that can cause microcracks by the impact of the silicon power generator during the curing process. The reason for this is that the cell thickness of silicon power generators has been manufactured to more than 200um in the past, but recently, they are manufactured to less than 200um in view of the shortage of silicon raw materials and material cost reduction. In addition, there are reports of problems in which the volume resistivity of the adhesive sheet is lower than that of the adhesive sheet before curing and thus the efficiency of the solar cell module is lowered and the defects of the solar cell due to outgassing and bubble generation of the adhesive sheet during the bonding process.
이에 본 발명의 목적은, 태양전지 제조시 진공 및 프레스 공정 중 접착시트의 경화 수축률을 낮추어 미세 크랙의 발생에 따른 실리콘 발전 소자의 불량률을 낮출 수 있도록 한 태양전지용 접착시트 조성물을 제공하는 것이다. Accordingly, an object of the present invention is to provide a solar cell adhesive sheet composition that can lower the curing shrinkage rate of the adhesive sheet during the vacuum and press process during solar cell manufacturing, thereby lowering the defect rate of the silicon power generation device due to the occurrence of microcracks.
본 발명의 다른 목적은 태양전지 제조시 진공 및 프레스 공정 중 접착시트의 아웃가스 및 기포 발생이 적어 태양전지의 불량률을 낮출 수 있는 태양전지용 접착시트 조성물을 제공하는 것이다.Another object of the present invention is to provide a solar cell adhesive sheet composition that can reduce the defect rate of the solar cell is less outgassing and bubbles generated in the adhesive sheet during the vacuum and press process during solar cell manufacturing.

바람직하게는 태양전지용 접착시트 조성물을 속경화형으로 제조하고자 하는 경우 상기 유기과산화물은 알킬퍼옥시에스테르 타입에서 선택되는 적어도 하나를 사용하는 것이 바람직하다. Preferably, when the adhesive sheet composition for a solar cell is to be manufactured in a fast curing type, the organic peroxide is preferably used at least one selected from the alkyl peroxy ester type.
또한, 태양전지용 접착시트 조성물을 속경화형이 아닌 표준경화형으로 제조하고자 하는 경우 상기 유기과산화물은 디알킬퍼옥사이드 타입에서 선택되는 적어도 하나와, 알킬퍼옥시에스테르 타입 및 퍼옥시케톤 타입에서 선택되는 적어도 하나를 혼합하여 이루어지는 혼합물 형태인 것이 바람직하다. 이때 혼합비율은 제한되지 않으나, 상기 혼합물 100중량부를 기준으로 할 때 디알킬퍼옥사이드 타입의 유기과산화물 10~90중량부, 알킬퍼옥시에스테르 타입 및 퍼옥시케톤 타입의 유기과산화물 90~10중량부로 이루어지는 것이 좋다.In addition, when the adhesive sheet composition for solar cells is to be manufactured in a standard hardening type rather than a fast curing type, the organic peroxide is at least one selected from a dialkyl peroxide type, and at least one selected from an alkyl peroxy ester type and a peroxy ketone type. It is preferable that it is a mixture form which mixes. At this time, the mixing ratio is not limited, but based on 100 parts by weight of the mixture 10 to 90 parts by weight of the organic peroxide of the dialkyl peroxide type, consisting of 90 to 10 parts by weight of the organic peroxide of the alkyl peroxy ester type and peroxy ketone type It is good.

If the amount of the organic peroxide used is less than 0.2 part by weight, there is a problem in that the ethylene copolymer resin cannot be sufficiently crosslinked. If the amount of the organic peroxide is more than 4 parts by weight, the crosslinking rate may be increased, but the shrinkage may increase and yellowing may not be prevented.

밀폐된 박스안에서 일반 글라스 / 이형지 필름/ 제조된 0.5mm 접착시트 2장 / 이형지 필름 / 일반 글라스 의 적층 구조를 만들고 150℃, 3분 진공 공정 및 150℃, 8분 프레스 공정을 진공 합착기를 이용하여 가교를 진행한다. 가교 공정이 끝난후 밀폐된 박스안에 주사기를 넣고 발생된 아웃가스를 TGA 측정기를 이용해서 아웃가스를 정량한다(Oven Temp. 50℃->20℃/분->150℃(30분).In a closed box, make a laminated structure of ordinary glass / release paper film / 2 sheets of 0.5mm adhesive sheet / release paper film / normal glass, and use 150 ℃, 3 minute vacuum process and 150 ℃, 8 minute press process Proceed to crosslinking. After completion of the crosslinking process, place the syringe in a sealed box and quantify the outgas by using a TGA meter (Oven Temp. 50 ° C-> 20 ° C / min-> 150 ° C (30 minutes).
상기 표 1에서 보는 바와 같이 에틸렌 공중합체 수지로 비닐 아세테이트 함량이 30~36%인 에틸렌 공중합체 수지(A)와 비닐 아세테이트 함량이 24~30%인 에틸렌 공중합체 수지(B)를 본 발명에 따라 혼합한 실시예의 경우 비교예에 비하여 경화전후의 체적변화가 적을 뿐만 아니라 수축률이 작고 아웃가스 발생량이 적은 것을 확인할 수 있다.As shown in Table 1 above, the ethylene copolymer resin (A) having a vinyl acetate content of 30 to 36% and the ethylene copolymer resin (B) having a vinyl acetate content of 24 to 30% are ethylene copolymer resins according to the present invention. In the case of the mixed examples, the volume change before and after curing was smaller than the comparative example, and the shrinkage rate was small and the outgas generation amount was small.
도 1은 본 발명의 일 실시예에 따른 태양전지 개략 단면도이다.1 is a schematic cross-sectional view of a solar cell according to an embodiment of the present invention.
