Abstract
Amorphous silicon solar cell has advantages of low processing cost and higher light absorption coefficient over crystalline silicon solar cell. However, short lifetime and instability against the light are the major drawbacks. This report aims to investigate the ways for achieving longer lifetime and robustness of amorphous silicon solar cell against the light. The potential solution of
Amorphous Silicon은 보통 staggered TFT가 사용되는데 그 이유는 a-Si:H의 높은 resistance때문이다.
Resistance 때문에 Gate와 overlap되는 source와 drain이 있는 TFT는 좋은 전기적 특성을 가지게 된다.
-Amorphous silicon is usually used for staggered TFT, because of the high resistance of a-Si:H.
Due to the resistance, the TFT where source & drain overlap wit
