Abstract :
We have newly developed novel PECVD method which we call "Cat-PECVD method". This method has been developed to combine PECVD method and Cat-CVD method. Microcrystalline-Si (/spl mu/c-Si:H) films prepared by this method at high deposition rate of more than 1 nm/sec with low substrate temperature of less than 250/spl deg/C showed high quality compared with the films by conventional PECVD method. Applying these films for single junction /spl mu/c-Si:H solar cells, intrinsic cell efficiency of 8.1% at 1.2 nm/sec and 7.3% at 1.9 nm/sec were achieved. Besides, these cells showed good stability of no post-degradation and no light-induced degradation.
