Isilicon ye-polycrystalline kunye nesilicon ye-monocrystalline zizinto ezimbini ezahlukeneyo, i-polycrystalline silicon ligama lemichiza elaziwa njengeglasi, i-high-purity polycrystalline silicon imathiriyeli yiglasi ecocekileyo, i-monocrystalline silicon yimathiriyeli ekrwada yokwenza iiseli ze-solar photovoltaic, kunye nemathiriyeli ukwenza iitshiphusi zesemiconductor.Izinto eziluhlaza ze-silicon ore zokuvelisa i-silicon ye-monocrystalline zinqabile kwaye inkqubo yokuvelisa inzima, ngoko ke imveliso iphantsi kwaye ixabiso liphezulu.Ke yintoni umehluko phakathi kweeseli zelanga ze-silicon ze-monocrystalline kunye neeseli zelanga ze-polycrystalline, kwaye yintoni engcono?
Okokuqala, umahluko kwimbonakalo
Ukusuka kwinkangeleko, iikona ezine ze-silicon ye-monocrystalline i-arc-shaped kwaye ayinayo ipateni phezu komhlaba;ngelixa iikona ezine ze-polycrystalline silicon cell zisikwere kwaye umphezulu unepateni efana neentyatyambo zomkhenkce;iseli ye-silicon ye-non-crystalline yinto esiyidla ngokuthetha ngeemodyuli zefilimu ezincinci, ngokungafani neeseli ze-crystalline ze-silicon, imigca yegridi ingabonwa, kwaye ubuso bucacile kwaye bugudileyo njengesibuko.
Okwesibini, sebenzisa lo mahluko ungentla
Kubasebenzisi, akukho mahluko ungako phakathi kweebhetri ze-silicon ze-monocrystalline kunye neebhetri ze-silicon ze-polycrystalline, kwaye ubomi bazo kunye nokuzinza zilungile kakhulu.Nangona i-avareji yokuguqulwa kokusebenza kakuhle kweeseli ze-silicon ze-monocrystalline imalunga ne-1% ephezulu kuneeseli ze-polycrystalline silicon, kuba iiseli ze-silicon ze-monocrystalline zingenziwa kuphela kwi-quasi-square (amacala amane ane-arc-shaped), kuya kubakho inxalenye indawo xa usenza iphaneli yelanga.Ayikwazi ukuzalisa;kwaye i-polysilicon isikwele, ngoko ke akukho ngxaki enjalo, iingenelo kunye nokungalunganga kwazo zimi ngolu hlobo lulandelayo:
Iimodyuli ze-crystalline silicon: Amandla emodyuli enye angaphezulu.Ngaphantsi konyawo olufanayo, umthamo ofakiweyo uphezulu kuneemodyuli zefilimu encinci.Nangona kunjalo, iimodyuli zinzima kwaye zibuthathaka, kunye nokusebenza kakubi kobushushu obuphezulu, ukusebenza kakubi kokukhanya okuphantsi, kunye nezinga eliphezulu lokubola konyaka.
Iimodyuli zefilimu encinci: Amandla emodyuli enye aphantsi.Nangona kunjalo, ukusebenza kokuveliswa kwamandla kuphezulu, ukusebenza kobushushu obuphezulu kulungile, ukusebenza kokukhanya okuphantsi kulungile, ukulahleka kwamandla omthunzi womthunzi kuncinci, kwaye izinga lokuthomalalisa lonyaka liphantsi.Indawo ebanzi yesicelo, intle kwaye ihambelana nokusingqongileyo.
Okwesithathu, umahluko kwinkqubo yokuvelisa
Amandla asetyenziswe kwinkqubo yokwenziwa kweeseli zelanga ze-polycrystalline silicon malunga ne-30% ngaphantsi kwe-monocrystalline silicon iiseli zelanga.Ke ngoko, iiseli ze-silicon ze-polycrystalline zelanga zibonelela ngesabelo esikhulu semveliso yeeseli zelanga zehlabathi, kwaye iindleko zokuvelisa nazo ziphantsi kuneeseli ze-silicon ze-monocrystalline.Ke ngoko, ukusetyenziswa kwe-polycrystalline silicon iiseli zelanga Kuya kuba ngaphezulu konga amandla kunye nokusingqongileyo!
Yiyiphi eyona nto ingcono kwi-silicon ye-monocrystalline okanye iiseli ze-silicon ze-polycrystalline zelanga?
Ukuguqulwa kwe-photoelectric ukusebenza kakuhle kweeseli zelanga ze-silicon ye-monocrystalline malunga ne-15%, kwaye iphakamileyo yi-24%, eyona nto iphezulu yokuguqulwa kwe-photoelectric phakathi kwazo zonke iintlobo zeeseli zelanga okwangoku, kodwa iindleko zokuvelisa ziphezulu kangangokuthi azikwazi ukusetyenziswa ngokubanzi. kunye nokusetyenziswa Ngokuqhelekileyo.Ekubeni i-silicon ye-monocrystalline ngokubanzi ifakwe kwiglasi epholileyo kunye ne-resin engenamanzi, yomelele kwaye yomelele, kwaye ubomi bayo benkonzo buhlala bufikelela kwiminyaka eyi-15, ukuya kuma-25 eminyaka.
Inkqubo yokuveliswa kweeseli zelanga ze-polycrystalline silicon ifana neyeeseli zelanga ze-silicon ze-monocrystalline, kodwa ukuguqulwa kwe-photoelectric ye-polycrystalline silicon iiseli zelanga zelanga ziphantsi kakhulu, kwaye ukuguqulwa kwe-photoelectric kusebenze malunga ne-12%.
Ngokwexabiso lemveliso, lixabiso eliphantsi kuneeseli zelanga ze-silicon ze-monocrystalline, izinto eziphathekayo zilula ukwenza, ukusetyenziswa kwamandla kugcinwa, kwaye ixabiso elipheleleyo lokuvelisa liphantsi, ngoko liphuhliswe kakhulu.Ukongeza, ubomi benkonzo yeeseli zelanga ze-polycrystalline silicon bufutshane kunobo beeseli zelanga ze-silicon ze-monocrystalline.Ngokubhekiselele ekusebenzeni kweendleko, iiseli zelanga ze-silicon ze-monocrystalline zingcono kancinci.
