I-polycrystalline silicon ne-monocrystalline silicon yizinto ezimbili ezihlukene, i-polycrystalline silicon yigama lamakhemikhali elivame ukubizwa ngokuthi ingilazi, i-high-purity polycrystalline silicon impahla iyingilazi ehlanzekile kakhulu, i-monocrystalline silicon iyimpahla eluhlaza yokwenza amaseli e-solar photovoltaic, kanye nezinto zokwakha. ukwenza ama-semiconductor chips.Izinto zokusetshenziswa ze-silicon ore zokukhiqiza i-silicon ye-monocrystalline ziyindlala futhi inqubo yokukhiqiza iyinkimbinkimbi, ngakho-ke okukhiphayo kuphansi futhi intengo iphezulu.Ngakho-ke uyini umehluko phakathi kwamaseli elanga e-monocrystalline silicon namaseli elanga e-polycrystalline, futhi yikuphi okungcono?
Okokuqala, umehluko ekubukekeni
Kusukela ekubukeni, amakhona amane e-monocrystalline silicon cell anomumo we-arc futhi awanayo iphethini ebusweni;kuyilapho amakhona amane e-polycrystalline silicon cell eyisikwele futhi indawo engaphezulu inephethini efana nezimbali zeqhwa;i-non-crystalline silicon cell yilokho esivame ukukhuluma ngamamojula amafilimu amancane, ngokungafani namaseli e-silicon e-crystalline, imigqa yegridi ingabonakala, futhi ubuso bucacile futhi bushelelezi njengesibuko.
Okwesibili, sebenzisa umehluko ongenhla
Kubasebenzisi, awukho umehluko omkhulu phakathi kwamabhethri e-monocrystalline silicon namabhethri e-polycrystalline silicon, futhi ubude bawo bokuphila nokuzinza kuhle kakhulu.Nakuba isilinganiso sokuguqulwa kokusebenza kahle kwamaseli e-silicon e-monocrystalline cishe siphakeme ngo-1% kunesamaseli e-polycrystalline silicon, njengoba amaseli e-silicon e-monocrystalline angenziwa kuphela abe i-quasi-square (izinhlangothi ezine zimise okwe-arc), kuzoba nengxenye indawo lapho wenza iphaneli yelanga.Ayikwazi ukugcwalisa;futhi i-polysilicon iyisikwele, ngakho-ke ayikho inkinga enjalo, izinzuzo nezingozi zabo zimi kanje:
Amamojula e-crystalline silicon: Amandla emojula eyodwa aphakeme kakhulu.Ngaphansi konyawo olufanayo, umthamo ofakiwe uphakeme kunalowo wamamojula wefilimu emincane.Kodwa-ke, amamojula asindayo futhi antekenteke, anokusebenza okungekuhle kwezinga lokushisa eliphezulu, ukusebenza kabi kokukhanya okuphansi, kanye nezinga eliphezulu lokubola konyaka.
Amamojula amafilimu amancane: Amandla emojuli eyodwa aphansi uma kuqhathaniswa.Kodwa-ke, ukusebenza kokukhiqizwa kwamandla kuphezulu, ukusebenza kwezinga lokushisa eliphezulu kuhle, ukukhanya okuphansi kokukhanya kuhle, ukulahleka kwamandla e-shading shading kuncane, futhi izinga lokunciphisa lonyaka liphansi.Indawo ebanzi yohlelo lokusebenza, enhle futhi enobungani bemvelo.
Okwesithathu, umehluko enqubweni yokukhiqiza
Amandla asetshenziswa ekukhiqizeni amaseli elanga e-polycrystalline silicon cishe angaphansi ngo-30% kunalawo amaseli elanga e-silicon e-monocrystalline.Ngakho-ke, amaseli elanga e-polycrystalline silicon elanga abangela ingxenye enkulu yokukhiqizwa kwamaseli elanga emhlabeni wonke, futhi izindleko zokukhiqiza nazo ziphansi kunalezo zamaseli e-silicon e-monocrystalline.Ngakho-ke, ukusetshenziswa kwamaseli elanga e-polycrystalline silicon Kuyoba ukonga kakhudlwana futhi kube nobungane bemvelo!
Yikuphi okungcono kumaseli elanga e-monocrystalline silicon noma e-polycrystalline silicon?
Ukusebenza kahle kokuguqulwa kwe-photoelectric kwamaseli elanga elanga e-monocrystalline silicon cishe ku-15%, futhi ephakeme kakhulu yi-24%, okuyiyona ndlela ephakeme kakhulu yokuguqulwa kwesithombe sikagesi phakathi kwazo zonke izinhlobo zamaseli elanga okwamanje, kodwa izindleko zokukhiqiza ziphezulu kangangokuthi azikwazi ukusetshenziswa kabanzi. futhi Okuvame ukusetshenziswa.Njengoba i-silicon ye-monocrystalline ngokuvamile imbozwa ngengilazi epholile kanye ne-resin engangeni manzi, iqinile futhi ihlala isikhathi eside, futhi impilo yayo yesevisi ngokuvamile ifinyelela eminyakeni engu-15, kuze kufike eminyakeni engu-25.
Inqubo yokukhiqiza yamangqamuzana elanga e-polycrystalline silicon ifana neyamaseli elanga e-silicon e-monocrystalline, kodwa ukusebenza kahle kokuguqulwa kwe-photoelectric kwamaseli elanga e-polycrystalline silicon aphansi kakhulu, futhi ukusebenza kahle kokuguqulwa kwe-photoelectric cishe ku-12%.
Mayelana nezindleko zokukhiqiza, ishibhile kunamaseli elanga e-monocrystalline silicon, impahla ilula ukwenza, ukusetshenziswa kwamandla kugcinwa, futhi izindleko zokukhiqiza eziphelele ziphansi, ngakho-ke iye yathuthukiswa kakhulu.Ngaphezu kwalokho, impilo yesevisi yamaseli elanga e-polycrystalline silicon nayo imfushane kunaleyo yamaseli elanga elanga e-silicon ye-monocrystalline.Mayelana nokusebenza kwezindleko, amaseli elanga e-silicon e-monocrystalline angcono kancane.
Inqubo yokukhiqiza yamangqamuzana elanga e-polycrystalline silicon ifana neyamaseli elanga e-silicon e-monocrystalline, kodwa ukusebenza kahle kokuguqulwa kwe-photoelectric kwamaseli elanga e-polycrystalline silicon aphansi kakhulu, futhi ukusebenza kahle kokuguqulwa kwe-photoelectric cishe ku-12%.Mayelana nezindleko zokukhiqiza, kubiza kancane kunamaseli elanga e-monocrystalline silicon, impahla ilula ukwenza, ukusetshenziswa kwamandla kuyagcinwa, futhi izindleko zokukhiqiza eziphelele ziphansi, ngakho-ke iye yathuthukiswa kakhulu.Ngaphezu kwalokho, impilo yesevisi yamaseli elanga e-polycrystalline silicon nayo imfushane kunaleyo yamaseli elanga elanga e-silicon ye-monocrystalline.Mayelana nokusebenza kwezindleko, amaseli elanga e-silicon e-monocrystalline angcono kancane.
Ngokuvamile, amaseli elanga emakethe asasebenzisa amakristalu awodwa.Ngokuyisisekelo, ubuchwepheshe buvuthiwe, imakethe inkulu, futhi ukulungiswa kulula kakhulu.
