Silicon zvinhu ndiyo inonyanya kukosha uye yakakosha zvinhu muindasitiri yesemiconductor.Iyo yakaoma yekugadzira maitiro eiyo semiconductor indasitiri chain inofanirawo kutanga kubva mukugadzirwa kweiyo yakakosha silicon zvinhu.
Monocrystalline silicon solar gadheni mwenje
Monocrystalline silicon imhando ye elemental silicon.Kana yakanyungudutswa elemental silicon ikaomesa, maatomu esilicon anorongwa mudhaimani retisi kuita akawanda ekristaro nuclei.Kana idzi nuclei dzekristaro dzichikura kuita tsanga dzine kutaridzika kwakafanana kwendege yekristaro, zviyo izvi zvinosanganiswa mukufanana kuti zvinyanye kuve monocrystalline silicon.
Monocrystalline silicon ine zvinhu zvemuviri zvequasi-metal uye ine isina simba magetsi conductivity, iyo inowedzera nekuwedzera tembiricha.Panguva imwecheteyo, monocrystalline silicon zvakare ine yakakosha semi-yemagetsi conductivity.Ultra-pure monocrystalline silicon is an intrinsic semiconductor.Iyo conductivity ye-ultra-pure monocrystal silicon inogona kuvandudzwa nekuwedzera trace ⅢA zvinhu (senge boron), uye P-mhando silicon semiconductor inogona kuumbwa.Zvakadai sekuwedzera kwekutsvaga ⅤA zvinhu (zvakadai se phosphorus kana arsenic) zvinogonawo kuvandudza dhigirii rekufambisa, kuumbwa kweN-mhando silicon semiconductor.
Polysilicon imhando ye elemental silicon.Kana yakanyungudutswa elemental silicon inoomesa pasi pemamiriro ekutonhorera, maatomu esilicon anorongwa mune akawanda ekristaro nuclei muchimiro chedhaimani lattice.Kana idzi nuclei dzekristaro dzichikura kuita tsanga dzine kwakasiyana crystal orientation, tsanga idzi dzinobatanidza nekupenya kuita polysilicon.Iyo yakasiyana nesilicon monocrystalline, iyo inoshandiswa mune zvemagetsi uye masero ezuva, uye kubva kune amorphous silicon, iyo inoshandiswa mune dzakatetepa-firimu zvishandiso uye.solar masero gadheni chiedza
Kusiyana uye kubatana pakati pezviviri izvi
Mune monocrystalline silicon, chimiro chekristaro chimiro chakafanana uye chinogona kuzivikanwa nechitarisiko chekunze chakafanana.Mune monocrystalline silicon, iyo crystal lattice yemuenzaniso wose inoenderera uye haina miganhu yezviyo.Makristasi makuru ega ega haawanzo shomekerwa mumasikirwo uye akaoma kugadzira murabhoritari (ona recrystallization).Mukupesana, nzvimbo dzeatomu muzvimiro zveamorphous zvinongogumira pakurongeka kwenguva pfupi.
Polycrystalline uye subcrystalline zvikamu zvinosanganisira nhamba huru yemakristasi madiki kana microcrystals.Polysilicon chinhu chinoumbwa neakawanda madiki esilicon makristasi.Masero ePolycrystalline anogona kuziva manyorerwo neinooneka sheet simbi mhedzisiro.Semiconductor mamakisi anosanganisira solar giredhi polysilicon anoshandurwa kuita monocrystalline silicon, zvichireva kuti makristasi akabatanidzwa mupolysilicon anoshandurwa kuita kristaro hombe.Monocrystalline silicon inoshandiswa kugadzira akawanda silicon-based microelectronic zvishandiso.Polysilicon inogona kuwana 99.9999% kuchena.Ultra-pure polysilicon inoshandiswawo muindasitiri yesemiconductor, senge 2 - kusvika 3-mita yakareba polysilicon tsvimbo.Muindasitiri yemicroelectronics, polysilicon ine maapplication pane ese macro uye diki zviyero.Maitiro ekugadzira emonocrystalline silicon anosanganisira iyo Czeckorasky maitiro, zone kunyungudika uye Bridgman maitiro.
Musiyano uripo pakati pepolysilicon uye monocrystalline silicon unonyanya kuratidzwa mune zvemuviri zvivakwa.Panyaya yemagetsi uye magetsi emagetsi, polysilicon yakaderera kune monocrystalline silicon.Polysilicon inogona kushandiswa seyakagadzirwa zvinhu zvekudhirowa monocrystalline silicon.
1. Panyaya ye anisotropy ye mechanical properties, optical properties uye thermal properties, zviri pachena zvishoma kudarika monocrystalline silicon.
2. Panyaya yezvivakwa zvemagetsi, iyo yemagetsi conductivity yepolycrystalline silicon haina kukosha zvakanyanya kupfuura iyo yemonocrystalline silicon, kana kunyangwe isina magetsi conductivity.
3, maererano nebasa remakemikari, musiyano pakati pezviviri idiki kwazvo, kazhinji shandisa polysilicon yakawanda
