polysilicon yog ib daim ntawv ntawm elemental silicon. Thaum molten elemental silicon solidifies nyob rau hauv supercooling tej yam kev mob, silicon atoms yog teem nyob rau hauv daim ntawv ntawm pob zeb diamond lattices rau tsim ntau siv lead ua nuclei. Yog tias cov pob zeb siv lead ua no loj hlob mus rau hauv cov nplej nrog cov qauv siv lead ua sib txawv, cov nplej no yuav ua ke thiab crystallize rau hauv polysilicon.
Kev siv lub ntsiab ntawm polysilicon yog ua rau ib leeg siv lead ua silicon thiab hnub ci photovoltaic hlwb.
Polysilicon yog cov khoom siv tseem ceeb tshaj plaws thiab cov khoom siv yooj yim hauv kev lag luam semiconductor, kev lag luam xov xwm hluav taws xob, thiab kev lag luam hnub ci photovoltaic cell. Nws yog tsuas yog siv los ua cov khoom siv raw rau semiconductors thiab yog cov khoom siv tseem ceeb rau kev ua ib qho siv lead ua silicon. Nws tuaj yeem siv los ua ntau yam transistors, rectifier diodes, thyristors, solar cells, integrated circuits, electronic computer chips, thiab infrared detectors.
