I-silicon ye-polycrystalline

I-Polycrystalline silicon iwuhlobo lwe-silicon eyisisekelo. Lapho i-silicon eyisisekelo encibilikisiwe iqina ngaphansi
izimo ezipholile kakhulu, ama-athomu e-silicon ahlelwe ngendlela ye-lattice yedayimane ukuze akhe amaningi
i-crystal nuclei. Uma lawa manuclei ekristalu ekhula abe izinhlamvu zekristalu ezinomumo ohlukile wendiza yekristalu, lezi
izinhlamvu zekristalu zihlangana ukwenza i-polycrystalline silicon. . Inani lokusetshenziswa: Ithrendi yokuthuthukiswa kwe-solar
amaseli angabonakala ohlelweni lwamanje lokuthuthukiswa kwamaseli elanga lamazwe ngamazwe.

I-silicon ye-polycrystalline ingasetshenziswa njengempahla eluhlaza yokudonsa i-silicon eyodwa yekristalu. Umehluko phakathi
I-silicon ye-polycrystalline kanye ne-silicon eyodwa ye-crystal ibonakala ikakhulukazi ezindaweni ezibonakalayo. Ngokwesibonelo,
i-anisotropy yezakhiwo zemishini, izakhiwo ze-optical kanye nezakhiwo ezishisayo azibonakali kangako
lokho kwe-silicon eyodwa ye-crystal; ngokwezakhiwo zikagesi, ukuqhutshwa kwe-silicon ye-polycrystalline
I-crystal nayo ayibalulekile kakhulu kunaleyo ye-crystal silicon eyodwa, futhi ayinakho ngisho nokuhamba kahle.
Mayelana nomsebenzi wamakhemikhali, umehluko phakathi kwalokhu okubili mncane. Polycrystalline Silicon kanye
I-silicon ye-monocrystalline ingahlukaniswa ngokubukeka kwayo, kodwa ukuhlonza kwangempela kudinga
ukuhlaziywa ukuze kunqunywe isiqondiso se-crystal plane, uhlobo lwe-conductivity kanye ne-resistivity ye-crystal.
