ʻO nā ʻokoʻa nui ma waena o N-type a me P-type monocrystalline silicon wafers no ka photovoltaic solar
ʻO nā ʻokoʻa nui ma waena o N-type a me P-type monocrystalline silicon wafers no nā photovoltaics solar.
Loaʻa i nā wafers silicon monocrystalline nā waiwai kino o nā quasi-metala, me ka conductivity nāwaliwali, a piʻi ka conductivity me ka piʻi ʻana o ka mahana. Loaʻa iā lākou nā waiwai semiconducting koʻikoʻi. Ma ka doping ultra-pure monocrystalline silicon wafers me ka liʻiliʻi o ka boron, hiki ke hoʻonui ʻia ka conductivity e hana i kahi semiconductor silicon P-type. Pēlā nō, hiki i ka doping me ka liʻiliʻi o ka phosphorus a i ʻole arsenic hiki ke hoʻonui i ka conductivity, e hana ana i ka semiconductor silicon type N. No laila, he aha nā ʻokoʻa ma waena o P-type a me N-type silicon wafers?
ʻO nā ʻokoʻa nui ma waena o P-type a me N-type monocrystalline silicon wafers penei:
Dopant: I loko o ka silikoni monocrystalline, ʻo ka doping me ka phosphorus e hana ia i ke ʻano N, a ʻo ka doping me ka boron e lilo ia i P-type.
Conductivity: N-type he electron-conducting, a P-type he hole-conducting.
Hana: ʻOi aku ka nui o ka phosphorus i loko o ka N-type, ʻoi aku ka nui o nā electrons manuahi, ʻoi aku ka ikaika o ka conductivity, a ʻoi aku ka haʻahaʻa o ka resistivity. ʻOi aku ka nui o ka boron i loko o ka P-type, ʻoi aku ka nui o nā puka i hana ʻia e ka hoʻololi ʻana i ke silika, ʻoi aku ka ikaika o ka conductivity, a me ka haʻahaʻa o ka resistivity.
I kēia manawa, ʻo P-type silicon wafers nā huahana nui i ka ʻoihana photovoltaic. He mea maʻalahi ka hana ʻana i nā wafer silika P-type a loaʻa nā kumukūʻai haʻahaʻa. ʻOi aku ka lōʻihi o ke ola ʻana o nā mea lawe silika N-type, a ʻoi aku ka paʻakikī o ke kaʻina hana. Hoʻopili ʻia nā wafers silika N-type me ka phosphorus, ʻaʻole hiki ke hoʻoheheʻe maikaʻi ʻia me ke silika. I ke kiʻi ʻana i ke koʻokoʻo, ʻaʻole hoʻokaʻawale ʻia ka phosphorus. P-type silika wafers ua doped me ka boron, ka mea i ka like segregation coefficient i ke silika, a me ka uniformity o ka dispersion maʻalahi ke kaohi.
