Photovoltaic Detection of Magnetic Resonance in a-Si:H Solar Cells |
| |
| Abstract: | The detection of magnetic resonance via the photovoltage (PDMR) is a sensitive method for investigating recombination and light-induced meta-stable defects in a-Si:H solar cells. The steady-state PDMR signals are dependent on the light intensity, microwave power and sample temperature. Particularly,the delay time of signal or the phase shift of lock-in amplifier is also dependent on the light intensity and temperature. For a given temperature and microwave power there is an optimum light intensity for the signal noise ratio. According to our results, a brief analysis and discussion are given. |
