Amaseli elanga angamadivayisi e-semiconductor aguqula ngokuqondile imisebe yelanga ibe amandla kagesi ngokusekelwe kumphumela we-photovoltaic wama-semiconductors.Manje amaseli elanga athengiswayo ahlanganisa ikakhulukazi lezi zinhlobo ezilandelayo: amaseli elanga e-monocrystalline silicon, amaseli elanga e-polycrystalline silicon, amaseli elanga e-amorphous silicon, namaseli okwamanje e-cadmium telluride, amaseli e-copper indium selenide, amaseli e-nano-titanium oxide azwelayo, amaseli elanga e-polycrystalline silicon Thin-film kanye namaseli elanga ezinto eziphilayo, njll. I-crystalline silicon (i-monocrystalline, i-polycrystalline) amaseli elanga adinga izinto zokusetshenziswa ze-silicon ezihlanzekile, ngokuvamile ezidinga ukuhlanzeka okungenani kwe-%, okungukuthi, umkhawulo wama-athomu okungcola angu-2 avunyelwe ukuba khona ku-silicon eyizigidi ezingu-10. ama-athomu.Izinto ze-silicon zenziwe nge-silicon dioxide (SiO2, eyaziwa nangokuthi isihlabathi) njengento eluhlaza, engancibilika futhi kususwe ukungcola ukuze kutholakale i-silicon emahhadla.Kusukela ku-silicon dioxide kuya kumaseli elanga, kuhilela izinqubo eziningi zokukhiqiza nezinqubo, ngokuvamile ezihlukaniswe zibe: i-silicon dioxide->i-silicon dioxide->metallurgical-grade silicon->high-purity trichlorosilane->high-purity polysilicon->monocrystalline silicon rod noma i-Polycrystalline silicon ingot 1 > i-silicon wafer 1 > iseli lelanga.
Amaseli elanga e-Monocrystalline silicon enziwa ikakhulukazi nge-silicon ye-monocrystalline.Uma kuqhathaniswa nezinye izinhlobo zamaseli elanga, amaseli e-silicon e-monocrystalline asebenza kahle kakhulu ekuguquleni.Ezinsukwini zokuqala, amaseli elanga e-silicon e-monocrystalline athatha ingxenye enkulu yemakethe, kwathi ngemuva kuka-1998, ahlehla ku-silicon ye-polycrystalline futhi athatha indawo yesibili engxenyeni yemakethe.Ngenxa yokushoda kwezinto zokusetshenziswa ze-polysilicon eminyakeni yamuva, ngemuva kuka-2004, isabelo semakethe se-silicon ye-monocrystalline sikhuphuke kancane, futhi manje amabhethri amaningi abonwa emakethe yi-silicon ye-monocrystalline.I-silicon crystal yamaseli elanga elanga e-monocrystalline silicon iphelele kakhulu, futhi izakhiwo zayo ezibonakalayo, zikagesi nezemishini zifana kakhulu.Umbala wamaseli ngokuvamile umnyama noma umnyama, ofaneleka ngokukhethekile ukusika zibe izingcezu ezincane ukwenza imikhiqizo encane yabathengi.Ukuguqulwa Okuphumelelayo Kuzuzwe Elabhorethri Ye-Monocrystalline Silicon Cells
Ikona %.Ukusebenza kahle kokuguqulwa kohwebo okuvamile kungu-10% -18%.Ngenxa yenqubo yokukhiqiza yamaseli elanga e-silicon e-monocrystalline, ngokuvamile ama-silicon ingots asele eqediwe angu-cylindrical, bese edlula ekusikeni->ukuhlanza->ukuhlangana kokusabalalisa->ukususwa kwe-electrode yangemuva->ukwenza ama-electrode->ukugqwala indawo ezungezile- > ukunciphisa ukuhwamuka.Ifilimu elibukisayo kanye nezinye izinhlaka zezimboni zenziwa imikhiqizo eqediwe.Ngokuvamile, amakhona amane amaseli elanga e-monocrystalline silicon ayindilinga.Ugqinsi lwamaseli elanga e-silicon e-monocrystalline ngokuvamile luwugqinsi oluwu-200uM-350uM.Umkhuba wamanje wokukhiqiza owokuthuthukela ekubeni mncane kakhulu kanye nokusebenza kahle kakhulu.Abakhiqizi be-solar baseJalimane baseJalimane baqinisekisile ukuthi i-silicon ye-monocrystalline engu-40uM ewugqinsi ingafinyelela ukusebenza kahle kokuguqulwa okungu-20%.Ekukhiqizeni amaseli elanga e-polycrystalline silicon, i-silicon ehlanzekile njengezinto ezingavuthiwe ayihlanjululwa ibe yikristalu eyodwa, kodwa iyancibilika bese iphonswa ezingothini ze-silicon eziyisikwele, bese icutshungulwa ibe yizingcezu ezincane kanye nokucutshungulwa okufanayo njenge-silicon eyodwa yekristalu.I-silicon ye-polycrystalline kulula ukuyibona ebusweni bayo.I-silicon wafer yakhiwe inombolo enkulu yezifunda ezicwebezelayo ezinobukhulu obuhlukahlukene (ubuso bucwebezelayo).
Iqembu lokusanhlamvu okuqondisiwe kulula ukuphazamisa ukuguqulwa kwe-photoelectric kusixhumi esibonakalayo sokusanhlamvu, ngakho-ke ukusebenza kahle kokuguqulwa kwe-polysilicon kuphansi kakhulu.Ngesikhathi esifanayo, ukuhambisana kwezakhiwo ze-optical, zikagesi kanye nemishini ye-polysilicon akufani ne-monocrystalline silicon amaseli elanga.Ukusebenza okuphezulu kakhulu kwelabhorethri ye-polycrystalline silicon solar cell yi-%, kanti ethengiswayo ngokuvamile iba ngu-10% -16%.I-polycrystalline silicon solar cell iyisiqephu esiyisikwele, esinezinga eliphezulu lokugcwalisa lapho senza amamojula elanga, futhi imikhiqizo mihle kakhulu.Ugqinsi lwamaseli elanga e-polycrystalline silicon luvamise ukuba wugqinsi luka-220uM-300uM, futhi abanye abakhiqizi bakhiqize amaseli elanga anogqinsi oluwu-180uM, futhi athuthukela ekubeni mncane ukuze onge izinto ze-silicon ezibizayo.Ama-wafer e-Polycrystalline ayizikwele ezinama-engeli angakwesokudla noma ama-rectangles, futhi amakhona amane ama-wafers angawodwa agxiliwe eduze kwendingilizi.
Le enembobo emise okwemali phakathi nesiqephu yikristalu eyodwa, engabonakala ngokubuka nje.
