| Research Abstract |
Improvement in a conversion efficiency of a-Si:H p-i-n solar cells were achieved by heat treatment with high-pressure H2O vapor. This treatment has a capability of curing poor solar cell characteristics.
We constructed the microwave transmittance measurement system to precisely measure the effective minority carrier lifetime with the two different wavelength light illumination. The present technique has a capability of application to monitoring semiconductor quality especially photosensitivity in semiconductor device processing.
