Itandukaniro riri hagati ya monocrystalline na polycrystalline izuba

Imirasire y'izuba ni ibikoresho bya semiconductor bihindura imirasire y'izuba mu buryo butaziguye ingufu z'amashanyarazi hashingiwe ku ngaruka ya Photovoltaque ya semiconductor.Noneho imirasire y'izuba igurishwa cyane cyane ikubiyemo ubwoko bukurikira: ingirabuzimafatizo z'izuba za monocrystalline, izuba rya polycrystalline silicon izuba, amorphous silicon izuba, hamwe na cadmium telluride selile, umuringa indium selenide selile, nano-titanium oxyde ikangurira selile, polycrystalline silicon Thin-film izuba ingirabuzimafatizo zikomoka ku mirasire y'izuba, n'ibindi. atom.Ibikoresho bya silicon bikozwe muri dioxyde ya silicon (SiO2, izwi kandi nkumucanga) nkibikoresho fatizo, bishobora gushonga hamwe n’umwanda ukurwaho kugirango ubone silikoni yuzuye.Kuva kuri dioxyde de silicon kugeza kumirasire y'izuba, ikubiyemo inzira nuburyo bwinshi bwo gukora, mubisanzwe bigabanijwemo ibice: silicon dioxide-> metallurgical-grade-silicon- ingot 1> silicon wafer 1> ingirabuzimafatizo.

Monocrystalline silicon selile selile ikozwe ahanini na silicon monocrystalline.Ugereranije nubundi bwoko bwimirasire yizuba, selile monocrystalline silicon ifite imikorere ihanitse cyane.Mu minsi ya mbere, izuba ryitwa monocrystalline silicon izuba ryiganjemo igice kinini cyisoko, hanyuma nyuma ya 1998, basubira muri silicon polycrystalline bafata umwanya wa kabiri kumugabane wisoko.Bitewe no kubura ibikoresho fatizo bya polysilicon mu myaka yashize, nyuma ya 2004, umugabane w’isoko rya silikoni ya monocrystalline wiyongereyeho gato, none bateri nyinshi zigaragara ku isoko ni silikoni ya monocrystalline.Silicon kristal ya monocrystalline silicon selile izuba riratunganye rwose, kandi optique, amashanyarazi na mashini birasa cyane.Ibara ry'utugingo ngengabuzima ahanini ni umukara cyangwa umwijima, bikwiriye cyane cyane gukata uduce duto kugirango dukore ibicuruzwa bito byabaguzi.Guhindura Ingaruka Byagezweho muri Laboratoire ya selile ya Monocrystalline

Ni%.Guhindura imikorere yubucuruzi busanzwe ni 10% -18%.Bitewe nuburyo bwo gukora ingirabuzimafatizo yizuba ya monocrystalline silicon, mubisanzwe ingirangingo ya silicon yarangije igice ni silindrike, hanyuma ikanyura mu gukata-> isuku- > kugabanuka.Filime yerekana nibindi bikoresho byinganda bikozwe mubicuruzwa byarangiye.Mubisanzwe, impande enye za selile monocrystalline silicon izuba ryizengurutse.Ubunini bwa selile monocrystalline silicon izuba ni 200uM-350uM.Ibicuruzwa bigezweho ni uguteza imbere ultra-thin kandi ikora neza.Uruganda rukora imirasire y'izuba mu Budage rwemeje ko silicon 40uM yuzuye ya monocrystalline ishobora kugera kuri 20% neza.Mu gukora ingirabuzimafatizo zikomoka ku mirasire y'izuba ya polycrystalline, silikoni ifite isuku nyinshi nk'ibikoresho fatizo ntabwo isukurwa muri kristu imwe, ahubwo irashonga ikajugunywa mu nganda ya silicon kare, hanyuma igatunganyirizwa mu bice bito kandi bigatunganywa nka silikoni imwe.Polycrystalline silicon iroroshye kumenya uhereye hejuru yayo.Wafer ya silicon igizwe numubare munini wuturere twa kristaline yubunini butandukanye (ubuso ni kristu).

Itsinda ryibinyampeke ryoroshye biroroshye kubangamira ihinduka ryamafoto yumurongo wa interineti, bityo imikorere ya polysilicon ikaba mike.Muri icyo gihe, guhuza ibintu bya optique, amashanyarazi nubukanishi bwa polysilicon ntabwo ari byiza nkibya selile monocrystalline silicon.Ubushobozi buhanitse bwa laboratoire ya polycrystalline silicon izuba ni%, naho iyicuruzwa muri rusange ni 10% -16%.Imirasire y'izuba ya polycrystalline ni igice cya kare, gifite igipimo cyinshi cyo kuzuza iyo ikora izuba, kandi ibicuruzwa ni byiza cyane.Umubyimba w'ingirabuzimafatizo z'izuba za polycrystalline muri rusange ni 220uM-300uM, kandi bamwe mu bakora inganda bakoze imirasire y'izuba ifite umubyimba wa 180uM, kandi baratera imbere kugira ngo babike ibikoresho bya silikoni bihenze.Wafers ya polycrystalline ni impande enye zingana cyangwa urukiramende, kandi impande enye za waferi imwe zegeranye hafi y'uruziga.

Imwe ifite umwobo umeze nkamafaranga hagati yikigice ni kristu imwe, ishobora kugaragara iyo urebye
