標題[題目] Question of solar cells.
時間Wed Jun 16 22:06:00 2010
1.In polycrystalline solar cells,the defects or even extrinsic impurities
are very often concentrated at the grain boundaries,which can have a
significant effect on the transport and recombination of charge carriers.
Please describe these grain boundaries effects.
2.Please explain the reason that the doping efficiency in amorphous silicon
solar cells is very low and the minority carrier lifetime decreases with
increasing doping concentration.
3.Please describe the strategies to improve the performance of the amorphous
silicon solar cells.
4.Please describe the characteristics of a microcrystalline silicon solar
cell in comparison with the amorphous silicon solar cell.
5.Please describe the characteristics of a microcrystalline silicon solar
cell in comparison with the amorphous silicon solar cell.
麻煩板上高手幫忙解惑一下。
感謝！！
