He aha ka polysilicon?

ʻO ka polysilicon kahi ʻano o ka silika elemental, ʻo ia kahi mea semiconductor i haku ʻia me nā kristal liʻiliʻi liʻiliʻi i hui pū ʻia.

I ka wā e paʻa ai ka polysilicon ma lalo o nā kūlana supercooling, hoʻonohonoho nā ʻātoma silikona i loko o ke ʻano lattice daimana i loko o nā nuclei aniani he nui. Inā ulu kēia mau nuclei i mau ʻano me nā ʻano aniani like ʻole, hui pū kēia mau hua i crystallize i polysilicon. ʻO ka polysilicon ka mea kumu maoli no ka hana ʻana i ka silikoni monocrystalline a lawelawe ʻo ia ma ke ʻano he ʻike kumu ʻike uila no nā mea semiconductor o kēia wā e like me ka naʻauao artificial, ka mana aunoa, ka hoʻoili ʻike, a me ka hoʻololi photoelectric. ʻO ke ʻano o ka hoʻomākaukau ʻana o ka polysilicon ka mea maʻamau ma ka waiho ʻana i ka hoʻoheheʻe silicon i loko o kahi kīʻaha quartz a laila hoʻomālili mālie iā ia e hana i nā kristal liʻiliʻi he nui i ka wā o ke kaʻina paʻa. ʻO ka mea maʻamau, ʻoi aku ka liʻiliʻi o ka nui o nā kristal polysilicon i hoʻomākaukau ʻia ma mua o ka silicon monocrystalline, no laila e ʻokoʻa iki ko lākou mau uila a me nā waiwai optical. Ke hoʻohālikelike ʻia me ka silicon monocrystalline, ʻoi aku ka haʻahaʻa o ka polysilicon i nā kumukūʻai hana a me ke kiʻekiʻe kiʻekiʻe o ka hoʻololi ʻana i ka photoelectric, e hoʻohana nui ʻia i ka hana ʻana o nā panela lā. Eia kekahi, hiki ke hoʻohana ʻia ka polysilicon i ka hana ʻana i nā mea semiconductor a me nā kaapuni hoʻohui.
