Iiseli zelanga zixhobo ze-semiconductor eziguqula ngokuthe ngqo ukukhanya kwelanga kumandla ombane ngokusekelwe kwimpembelelo ye-photovoltaic ye-semiconductors.Ngoku iiseli zesolar ezithengiswayo ziquka ezi ntlobo zilandelayo: iiseli zelanga ze-monocrystalline silicon, iiseli zelanga ze-polycrystalline silicon, iiseli zelanga ze-amorphous silicon, kunye neeseli ze-cadmium telluride okwangoku, iiseli ze-copper indium selenide, iiseli ze-nano-titanium oxide, i-polycrystalline silicon Thin-film iiseli zelanga. kunye neeseli zelanga ze-organic, njl njl. I-crystalline silicon (i-monocrystalline, i-polycrystalline) iiseli zelanga zifuna izinto eziluhlaza ze-silicon ezicocekileyo, ngokubanzi zifuna ukucoceka ubuncinane be-%, oko kukuthi, ubuninzi be-athomu ezingcolileyo ze-2 zivumelekile ukuba zibekho kwi-silicon yezigidi ezili-10. iiathom.Izinto ze-silicon zenziwe nge-silicon dioxide (i-SiO2, eyaziwa ngokuba yintlabathi) njengento ekrwada, enokuthi inyibilike kwaye ukungcola kususwe ukuze kufumaneke i-silicon erhabaxa.Ukusuka kwisilicon dioxide ukuya kwiiseli zelanga, kubandakanya iinkqubo ezininzi zokuvelisa kunye neenkqubo, eziye zahlulahlulwe ngokubanzi zibe: isilicon dioxide->isilicon dioxide->metallurgical-grade silicon->high-purity trichlorosilane->high-purity polysilicon->monocrystalline silicon rod okanye Polycrystalline silicon ingot 1 > isilicon wafer 1 > iseli yelanga.
Iiseli zelanga ze-silicon ze-Monocrystalline zenziwe ikakhulu ngesilicon ye-monocrystalline.Xa kuthelekiswa nezinye iintlobo zeeseli zelanga, iiseli ze-silicon ze-monocrystalline zineyona ndlela iphezulu yokuguqula.Kwiintsuku zokuqala, iiseli zelanga ze-silicon ze-monocrystalline zathatha uninzi lwesabelo semarike, kwaye emva ko-1998, babuyela kwi-polycrystalline silicon kwaye bathatha indawo yesibini kwisabelo semarike.Ngenxa yokunqongophala kwezinto eziluhlaza ze-polysilicon kwiminyaka yakutshanje, emva kuka-2004, isabelo semarike se-silicon ye-monocrystalline sinyuke kancinci, kwaye ngoku uninzi lweebhetri ezibonwayo kwimarike yi-silicon ye-monocrystalline.I-silicon crystal yeeseli zelanga ze-silicon ye-monocrystalline igqibelele kakhulu, kwaye i-optical yayo, i-electric and mechanical properties ifana kakhulu.Umbala weeseli ubukhulu becala umnyama okanye umnyama, ofanelekileyo ngokukodwa ukusika kwiincinci ezincinci ukwenza iimveliso ezincinci zabathengi.Uguqulo oluSebenzayo luphunyeziwe kwiLebhu yeeSeli zeSilicon zeMonocrystalline
Yi %.Ukusebenza kokuguqulwa korhwebo oluqhelekileyo yi-10% -18%.Ngenxa yenkqubo yokuvelisa iiseli zelanga ze-silicon ze-monocrystalline, ngokuqhelekileyo ii-silicon ingots ezigqityiweyo ziyi-cylindrical, kwaye emva koko zihamba nge-slicing-> ukucoca-> i-diffusion junction-> ukususwa kwe-electrode yangasemva-> ukwenza i-electrodes-> ukugqwesa i-periphery- >ukunciphisa umphunga.Ifilimu ebonakalisayo kunye nezinye iicores zemizi-mveliso zenziwe kwiimveliso ezigqityiweyo.Ngokubanzi, iikona ezine zeeseli zelanga ze-silicon ze-monocrystalline zingqukuva.Ubukhulu beeseli zelanga ze-silicon ye-monocrystalline ngokuqhelekileyo yi-200uM-350uM ubukhulu.Indlela yangoku yemveliso kukuphuhlisa ukuya kwi-ultra-thin and high-efficiency.Abavelisi beeseli zelanga baseJamani baqinisekisile ukuba i-silicon ye-40uM engqingqwa ye-monocrystalline inokufikelela kwi-20% yokuguqulwa ngempumelelo.Kwimveliso yeeseli zelanga ze-polycrystalline silicon, i-silicon ecocekileyo ephezulu njengesixhobo ekrwada ayicocwanga ibe yikristale enye, kodwa iyanyibilika kwaye iphoswe kwii-ingots ze-silicon ezisikweri, emva koko zicutshungulwe zibe ziziqwenga ezicekethekileyo kunye nokusebenza okufanayo njengesilicon enye yekristale.I-silicon ye-polycrystalline kulula ukuyichonga ukusuka kumphezulu wayo.I-silicon wafer yenziwe ngenani elikhulu lemimandla ye-crystalline yobukhulu obuhlukeneyo (umphezulu yikristale).
Iqela leenkozo elijoliswe kuyo lilula ukuphazamisa ukuguqulwa kwe-photoelectric kwi-interface yengqolowa, ngoko ke ukuguqulwa kokusebenza kakuhle kwe-polysilicon kuncinci.Ngexesha elifanayo, ukuhambelana kwezinto ezibonakalayo, zombane kunye nezixhobo ze-polysilicon azilungile njengeeseli zelanga ze-silicon ze-monocrystalline.Obona buchule buphezulu belebhu ye-polycrystalline silicon yeseli yelanga yi-%, kwaye leyo yorhwebo idla ngokuba yi-10% -16%.I-polycrystalline i-silicon ye-solar cell yiqhekeza lesikwere, esinezinga eliphezulu lokuzalisa xa usenza iimodyuli zelanga, kwaye iimveliso zihle kakhulu.Ubukhulu beeseli zelanga ze-silicon ye-polycrystalline buyi-220uM-300uM ubukhulu, kwaye abanye abavelisi bavelise iiseli zelanga ezinobunzima be-180uM, kwaye baphuhlisela ukubhitya ukuze basindise izixhobo ze-silicon ezibizayo.Ii-polycrystalline wafers zizikwere ezine-angle ekunene okanye iirectangles, kwaye iikona ezine ze-wafers enye zine-chamfered kufutshane nesangqa.
Lowo unomngxuma omile okwemali embindini weqhekeza yikristale enye, enokubonwa ngokukrwaqula.
