摘　　要：本文首次报道p^+-i-n^+a-Si:H太阳电池的注入电流检测磁共振研究。实验研究了该自旋有关的注入电流效应与正向注入电流、辐照光强以及光电压检测磁共振(PDMR)的关系。结果表明该效应有比PDMR更高的灵敏度,可用于非晶及晶体势垒器件的例行检测。An investigation of Spin-dependent recombination process in p^+-i-n^+ a-Si:H Solar cellby forward injected current detection of Magnetic resonance is reported, for the first time.The effects of injected current, illumination on magnetic resonanance signal intensity detectedby injected current were studied. The results show that the sensitivity of injected current detectionof magnetic resonance is higher than PDMR and this method is suitable for routine assessmentfor both amorphous and crystalline photovoltaic junction and barrier devices.
