polysilicon ke mofuta oa silicon ea mantlha, e leng thepa ea semiconductor e entsoeng ka likristale tse ngata tse nyane tse kopantsoeng hammoho.
Ha polysilicon e tiea tlas'a maemo a batang haholo, liathomo tsa silicon li hlophisoa ka mokhoa oa lesela la daemane ho etsa li-nuclei tse ngata tsa kristale. Haeba li-nuclei tsena li hola ho ba lijo-thollo tse nang le libopeho tse fapaneng tsa kristale, lithollo tsena li kopana ho hola ho ba polysilicon. polysilicon ke thepa e tala e tobileng bakeng sa ho hlahisa silicon ea monocrystalline 'me e sebetsa e le lisebelisoa tsa motheo tsa tlhahisoleseding ea elektroniki bakeng sa lisebelisoa tsa semiconductor tsa mehleng ena tse kang bohlale ba maiketsetso, taolo ea boiketsetso, ts'ebetso ea tlhahisoleseding le phetoho ea photoelectric. Mokhoa oa ho lokisa oa polysilicon hangata ke ka ho beha silicon e qhibiliha ka har'a crucible ea quartz ebe o e pholisa butle-butle ho etsa likristale tse ngata tse nyane nakong ea ts'ebetso ea ho tiisa. Hangata, boholo ba likristale tsa polysilicon tse lokiselitsoeng li nyane ho feta tsa silicon ea monocrystalline, kahoo thepa ea bona ea motlakase le ea optical e tla fapana hanyane. Ha ho bapisoa le silicon ea monocrystalline, polysilicon e na le litšenyehelo tse tlaase tsa tlhahiso le katleho e phahameng ea ho fetola photoelectric, e leng se etsang hore e sebelisoe haholo ha ho etsoa liphanele tsa letsatsi. Ho feta moo, polysilicon e ka boela ea sebelisoa ha ho etsoa lisebelisoa tsa semiconductor le li-circuits tse kopantsoeng.
