이하 본 발명의 구성 및 실시예를 첨부된 도면에 따라 상세히 설명하면 다음과 같다. 도 1은 컷팅단락부(20)가 세로 방향으로 하여 나누어진 셀수단(18)을 직렬연결부(30)로 연결하여 만든 카드형태의 태양전지(100)의 구조를 보인 평면도이며, 지갑에 수납하기 편하도록 카드 형태의 직사각형의 모양과 카드의 크기와 같거나 비슷한 크기로 하며, 직사각형 모양의 각 면에서 일측에 휴대폰, 또는, 아이패드의 충전단자에 꽃아 충전할 수 있도록 한 를 출력플러그단자(50)를 접착, 용접, 조립 등으로 고정하여 일체화시켜 구비할 수 있으며, 바람직하게는 직사각형의 모양에서 네 귀퉁이 중 컷팅 된 꼭지점부(11)의 두 면의 90도 각을 같은 치수로 커트하고, 그 중심에서 출력플러그단자(50)를 구비하며, 출력플러그단자(50)의 꽃는 방향이 제거된 꼭지점부(11)의 방향으로 구비된 것으로 하며, 제거된 꼭지점부(11)의 범위를 넘지않게 출력플러그단자(50)가 구비된다. 수광부(10)는 태양전지에서 햇빛을 받아들여 실질적으로 전기를 생산하는 부위이고, 핑거전극(15)은 수광부(10)에서 생산된 전기를 수집하여, 전기저항이 적은 버스바전극(17)으로 모이게 하여, 출력플러그단자(50)로 연결되게 한다. 휴대폰의 배터리 전압은 약 4V에서 6V의 전압을 사용하고, 태양전지 종류마다 차이가 있지만, 한 개의 셀수단(18)에서 생산되는 전압은 약 1.1V에서 1.6V이므로 3개 내지 4개의 셀수단(18)을 직렬연결하여야 원하는 값의 전압을 만들 수 있으며, 도 1에서 한 개의 셀에 컷팅단락부(20)에서 보는 것처럼 레이저 빔으로 수광부(10)와 버스바전극(17)에 홈을 구비하여 각 셀수단(18)으로 분리하고, 각 셀수단(18)에 구비된 버스바전극(17)에서 다음 셀수단(18)의 배면 전극에 역시 레이저로 홀을 가공하여 배면전극접지부(28)와이어전극(25)으로 연결한다. 즉 한 개의 셀수단(18)의 버스바전극접지부(22)에서 다음 셀수단(18)의 배면전극접지부(28)에 와이어전극(25)으로 연결하며, 이때, 배면전극접지부(28)에 와이어전극(25)를 연결하기 위한 콘택트 홀을 레이저 빔으로 가공하여 그 콘택트 홀로 와이어전극(25)을 삽입하고 배면으로 빼내어 배면전극접지부(28)에 용접 작업 된다. 이러한 방식으로 각 셀수단(18)이 전기적으로 직렬 연결되어 전압을 높이고, 최종적으로 역전류차단다이오드(40)를 거쳐서 출력플러그단자(50)에 연결한다. 역전류차단다이오드(40)는 다이오드 기능 중 한 부분인 전류가 한쪽으로만 흐르는 성질을 이용한 것으로 부하 측으로 전류는 흐르되 부하 측에서 전류가 흘러들어오지 못하도록 차단하는 역할을 한다. 출력플러그단자(50)에는 버스바전극(17)에서 플러스전류와 배면 전극에서 마이너스전기가 모두 연결되며, 배면 전극을 출력플러그단자(50)에 연결할 때 배면에서 직접 출력플러그단자(50)에 연결하는 것이 바람직하며, 만약 윗면으로 해서 연결할 때는 레이저빔으로 콘택트 홀을 가공하여 배면전극콘텍부(45)에서 전극와이어수단으로 연결한다. 도 1에서 보는 바와 같이 핑거전극(15)이 카드형태의 폭의 방향으로 구비되고, 길이 방향으로 버스바전극(17)이 구비되게 하여, 컷팅단락부(20)가 폭의 방향으로 구비할 수 있으며, 도 2에서 카드형태의 태양전지(110)를 보는 바와 같이 핑거전극(15)이 카드형태의 태양전지(120)의 길이 방향으로 구비되고, 버스바전극(17)이 폭의 방향으로 구비되어, 컷팅단락부(20)가 길이방향으로 만들 수도 있다. 이러한 구성은 제조사가 사용되는 태양전지 종류에 따라 선택하여 작업할 수 있다. 도 3, 도 4에서 보다 큰 전류 값을 얻기 위하여 카드모양과 크기를 가진 각 셀수단(19)을 길이 방향, 또는, 폭의 방향으로 힌지부(60)로 연결 구비하여 자유롭게 접혀져서 포개지도록 구비하며, 각 힌지부(60)에서 직렬연결부(35)로 직렬로 연결하며, 이때는 플렉시블전극(26)을 사용하여 힌지부(60)에서 접혀질 때 플렉시블전극(26)이 같이 접혀져서 포개질 수 있도록 하며, 그중 양끝에 있는 한 개의 셀수단(19)에 도 1에서 설명한 방식으로 출력플러그단자(50)를 구비하여, 여려 개의 셀수단(19)이 접혀질 수 있도록 구비된 카드형태의 태양전지(120), 카드형태의 태양전지(130)를 만든다. 힌지부(60)에서 각 셀수단(19)의 끝 부를 양쪽에서 필름으로 접합시켜서 필름이 힌지 역할을 할 수 있으며, 또는, 섬유를 접합시켜, 접합 된 섬유가 힌지 역할을 할 수 있고, 또는, 실리콘으로 접합시켜 실리콘이 힌지 역할을 할 수 있으며, 또는, 고무로 접합 및 조립하여, 고무가 힌지 역할을 할 수 있다. 상기와 같이 만들어진 카드형태의 태양전지(100)는 실리콘의 다 결정 태양전지, 단결정 태양전지로 만들 수도 있으며, 또는, 얇은 유리기판, 스테인리스 금속기판에 실리콘을 증착하여 만든 박막 태양전지일 수도 있다. 또한, 스테인리스 박막기판에 CIGS, CdTe등의 소재를 증착하여 만든 플렉시블 박막태양전지를 사용할 수 있다.
