초록

태양전지의 전력향상을 위해 외부에 연결된 시스템적인 접근방법으로써 가변병렬공급기(DC1)와 가변직렬공급기(DC2)가 부착된 전자 전달 증대기(Electron Relay Enhancer: ERE)를 이용한 연구를 수행하였다. DC1의 전압이 태양전지 전압보다 높을 경우 DC1은 저항과 같은 역할을 하므로 태양전지의 전압이 상승하게 되고 반면 전류는 낮아지게 된다. 이 때 낮아진 전류는 DC2에서 보충해주어 태양전지의 출력이 증가하게 된다. DC ERE 직-병렬 시스템은 병렬 전압의 1.5~2.0 V 증가로 태양전지의 전압을 2.0~3.0 V 높일 뿐 아니라 전력 증가율도 약 10% 정도 향상시켰다.

The studies to improve the power of Solar Cell using ERE (Electron Relay Enhancer) system with Variable parallel-feeder (DC1) and variable series-feeder (DC2) were carried out. For DC1 voltage was higher than that of Solar Cell, this was raised because that functioned as a load, whereas a current was lowed. At that moment, the power of the Solar Cell was increased because the DC2 replenished the lower current. Not only increased the DC ERE series-parallel system the voltage of Solar Cell to 2.0~3.0 V, but they also increased the rate of power increase to about 10%.
