본문내용

Efficiency of Solar cell: broken down by
reflectance efficiency
thermodynamic efficiency
charge carrier separation efficiency
conductive efficiency.

Single crystal wafer: very expensive process, but higher efficiency
Polycrystalline wafers: by a casting process in molten silicon, cheaper process,
but lower efficiency from the imperfections in the crystal structure
Amorphous silicon: one of thin film technology, made by deposition process

[향후 Solar cell은 매년 15% 정도의 비율로 가격 하락 예상.
Solar cell의 효율 증가, 제조기술 향상, 규모의 경제 (대량 생산)]
