More particularly, the present invention relates to an apparatus for depositing a buffer layer during a manufacturing process of a thin-film solar cell, which comprises a non-vacuum system, Speed and a temperature of a plating solution are maintained at optimum working conditions, thereby obtaining a better working result. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a non-vacuum buffer layer deposition apparatus for a thin film solar cell.

CIGS 박막 태양전지(이하, 박막 태양전지)는 우수한 특성, 즉 높은 광흡수계수와 태양광 스펙트럼과 잘 일치하는 흡수 파장대를 가지고 있어 이미 미국, 독일, 일본과 같은 선진국에서는 오래전부터 연구개발을 해왔고 최근 수년 사이에 양산 기술을 개발하여 시장에 제품을 내놓기 시작하였다.CIGS thin film solar cells (hereinafter referred to as "thin film solar cells") have already been researched and developed in advanced countries such as the USA, Germany and Japan for a long time since they have excellent characteristics, namely, high absorption coefficient and absorption wavelength band that agrees well with the solar spectrum. Within a few years, we started to develop mass production technology and put products into the market.

이와 같은 박막 태양전지는 CdS, Zn(O.S.OH), In(OH)3ZnSe 등으로 버퍼층이 형성되는데, 상기 버퍼층은 증착작업시 화합물의 물성 및 두께에 따른 막의 균일도와 외부환경 및 공정변수를 일정하게 고정하여 재현성을 확보하는 것에 상당한 기술력을 요구하고 있다.
In the thin film solar cell, a buffer layer is formed of CdS, Zn (OSOH), In (OH) 3ZnSe or the like. The buffer layer has a uniform uniformity of the film according to the physical properties and thickness of the compound, And a considerable technical force is required to ensure reproducibility.

대한민국 특허출원 제10-2011-0033021호(CIGS 태양전지 제조 장치 및 방법, 이하 기출원발명)에는 광흡수층을 균일하게 증착하기 위한 구성이 제시되고 있다.Korean Patent Application No. 10-2011-0033021 (CIGS solar cell manufacturing apparatus and method, hereinafter referred to as original invention) discloses a structure for uniformly depositing a light absorbing layer.

기출원발명은 CIGS 태양전지의 광흡수층을 증착하는 장치로서, 상기 장치는 상기 기판에 광흡수층이 증착되도록 하는 도금액이 저장되는 수용부와, 상기 수용부에 설치되는 전극과 상기 기판 및 전극에 전원을 공급하는 전원부를 구비하는 도금부와, 상기 수용부가 장치되어 진공 분위기를 제공하는 진공 챔버와, 상기 진공 챔버 일측에 배치되는 진공 펌프를 포함하여 구성된다.The present invention relates to an apparatus for depositing a light absorbing layer of a CIGS solar cell, the apparatus comprising: a housing for storing a plating solution for depositing a light absorbing layer on the substrate; an electrode provided on the housing, And a vacuum pump disposed at one side of the vacuum chamber. The vacuum pump includes a vacuum pump and a vacuum pump.

또한, 기출원발명은 상기 태양전지 제조 장치를 이용하여 광흡수층을 증착하는 방법으로서, 상기 광흡수층이 증착되는 기판을 진공분위기가 유지되는 상태에 배치하는 한편 전기증착법에 의해 상기 광흡수층이 상기 기판에 증착되는 단계를 포함하여, 상기 광흡수층이 증착되는 동안 산소와 수소 기포가 외부로 배출되도록 하여 CIGS 태양전지를 제조하게 된다.The present invention also provides a method of depositing a light absorbing layer using the above-described solar cell manufacturing apparatus, wherein the substrate on which the light absorbing layer is deposited is placed in a state in which a vacuum atmosphere is maintained, And the oxygen and hydrogen bubbles are discharged to the outside while the light absorption layer is being deposited, thereby manufacturing a CIGS solar cell.

이러한 기출원발명은 CIGS 태양전지의 생산 비용을 절감하는 한편 산소와 수소 기포가 광흡수 층에 포함되지 않도록 하여 균일한 두께의 광흡수층이 증착되도록 하므로써 보다 우수한 품질의 제품을 얻을 수 있게 된다고 제시되고 있다.
The inventor of the present invention has proposed that a better quality product can be obtained by reducing the production cost of the CIGS solar cell and preventing the oxygen and hydrogen bubbles from being included in the light absorption layer to deposit a light absorption layer having a uniform thickness have.

상기와 같은 기출원발명의 CIGS 태양전지 제조장치는 기존의 진공증착 방식에 비해 경제적이라고는 하지만, 기본적으로 진공분위기 상에서 작업을 실시하기 위해 상당한 크기의 챔버와, 챔버 내부를 진공으로 형성하기 위한 진공펌프 등의 대형 장치를 요구하게 되며, 이와 같은 챔버 및 진공펌프 등의 구성에 의해 작업설비를 구성함에 따른 제조원가의 상승은 여전히 잔존하게 된다.Although the CIGS solar cell manufacturing apparatus of the present invention described above is economical compared with the conventional vacuum deposition system, it has a chamber having a considerably large size for performing work in a vacuum atmosphere and a vacuum chamber for forming a vacuum inside the chamber Pump, and the like, and an increase in the manufacturing cost due to the construction of the working facility by the configuration of the chamber and the vacuum pump and the like still remains.

또한, 상기와 같은 기출원발명의 CIGS 태양전지 제조장치는 챔버 내부에서 실시되는 작업상황을 정확하게 파악하기 위한 구성이 마련되지 않아 경험적인 작업조건을 구현하여 작업을 실시하고 있기 때문에 제품의 품질 향상을 기대하기 어려운 문제점이 노출된다.
