Hlola izimiso, izici, izinzuzo, kanye nokusetshenziswa kobuchwepheshe bamaseli elanga e-TOPCon, HJT, Perovskite, kanye ne-IBC.
Ubuchwepheshe be-TOPCon (Tunnel Oxide Passivated Contact)
Izimiso nezici:
I-TOPCon ubuchwepheshe bamaseli elanga obusekelwe ezimisweni zokuthwala ezikhethiwe. Inezela ungqimba lwe-silicon dioxide oluncane kakhulu (1–2 nm) kanye nongqimba lwe-polysilicon oluhlanganisiwe ukuze kwakheke isakhiwo sokuxhumana esingenasivikelo. Lokhu kunciphisa kakhulu ukuhlanganiswa kwendawo kanye nokuhlanganiswa kokuxhumana kwensimbi. Amaseli e-TOPCon ane-voltage ephezulu ye-open-circuit (Voc), izici zokugcwalisa ezinhle kakhulu (FF), kanye nobuningi bamanje be-recombination obuphansi (J0).
Izicelo:
Amaseli e-TOPCon afaneleka kakhulu ezimweni ezidinga amaphaneli elanga asebenza kahle kakhulu, njengezitshalo zamandla ezinkulu ze-photovoltaic (PV) kanye nezinhlelo zophahla. Ukwehla kokusebenza kwawo okuncane ezindaweni ezinokushisa okuphezulu kuwenza afaneleke kakhulu ezindaweni ezishisayo.
Ukubaluleka kanye nezinzuzo:
Ngomkhawulo wokusebenza kahle kwethiyori ongu-28.7%, i-TOPCon iphakathi kobuchwepheshe bamaseli elanga obusebenza kahle kakhulu. Ithuthukisa ukusebenza kahle ngokuthuthukisa othintana nabo abakhethekile futhi ingahlanganiswa kalula nemigqa yokukhiqiza amaseli e-silicon akristalu akhona, inciphise izindleko kanye nezithiyo zobuchwepheshe zokuthuthukiswa kwezimboni.
Ubuchwepheshe be-HJT (Heterojunction ne-Intrinsic Thin-Layer)
Izimiso nezici:
I-HJT ihlanganisa i-silicon ekristali nobuchwepheshe befilimu encane ukudala isakhiwo esilinganayo esinamacala amabili. Isebenzisa amafilimu e-silicon angaphakathi angenawo ukwakheka kanye namafilimu e-silicon angenawo ukwakheka ezinhlangothini zombili ze-wafer ye-silicon yohlobo lwe-N, yakha i-PN junction. Ama-oxide e-conductive acacile (ama-TCO) enza kube lula ukuqhuba.
Izicelo:
Amaseli e-HJT, asebenza kahle kakhulu kanye nokuwohloka okubangelwa ukukhanya okuphansi (i-LID), afaneleka ezinhlelweni zokusebenza eziphezulu njengezinhlelo ze-PV zophahla, ama-agrivoltaics, kanye nama-photovoltaics ahlanganisiwe esakhiwo (i-BIPV).
Ukubaluleka kanye nezinzuzo:
Ubuchwepheshe be-HJT bunikeza ukusebenza kahle kokukhiqiza okungaphezu kuka-24%, kanye nekhono lokudlula u-30%. Izinzuzo zalo zifaka phakathi ukumelana ne-LID kanye ne-PID (ukubola okubangelwa amandla), ama-coefficients okushisa okuphansi, ubukhulu obuphezulu, kanye nokusebenza okuphezulu kokukhanya okuphansi. Lezi zici ziqinisekisa ukukhiqizwa kwamandla aphezulu kanye nezinzuzo zomnotho ngaphezu kwamaseli avamile e-PERC.
Amaseli Elanga ePerovskite
Izimiso nezici:
Amaseli elanga e-Perovskite asebenzisa ama-semiconductor e-halide angaphili anesakhiwo se-ABX3 njengezinto ezimunca ukukhanya. Abonisa ama-coefficients aphezulu okumunca, ubude bokusabalalisa kwe-carrier ende, kanye nama-bandgaps angashintshwa.
Izicelo:
Amaseli e-Perovskite ayakwazi ukushintshashintsha, asebenza ezitshalweni zamandla ezinkulu, i-BIPV, kanye nokukhiqizwa kwamandla okukhanya okuphansi ngaphakathi endlini.
Ukubaluleka kanye nezinzuzo:
Amaseli e-Perovskite afinyelele ukusebenza kahle kwelebhu okufika ku-25.7%, kanye nendawo yokuthuthuka okwengeziwe. Anikeza izindleko zezinto eziphansi, ukukhiqizwa kwezinga lokushisa eliphansi, kanye nokusebenza okuvelele ezindaweni ezinokukhanya okuphansi, okwenza abe yisisombululo esithembisayo sezidingo zamandla ezahlukahlukene.
Ubuchwepheshe be-IBC (Interdigitable Back Contact)
Izimiso nezici:
I-IBC isusa ama-electrode angaphambili ngokubeka zonke izixhumanisi ohlangothini lwangemuva lweseli, isuse izithiyo zokumunca ukukhanya futhi ithuthukise ukusebenza kahle kokuguqulwa.
Izicelo:
Amaseli e-IBC ayathandwa ezimakethe ze-premium, njengezinhlelo zophahla ezisezingeni eliphezulu kanye nezixazululo ze-BIPV ezihlanganiswe ngobuhle.
Ukubaluleka kanye nezinzuzo:
Ubuchwepheshe be-IBC buvumela ukusebenza kahle okuphezulu kanye nobuhle obuthuthukisiwe. Izinzuzo zayo zifaka phakathi ukumelana okuncishisiwe kochungechunge, ukubekezelela okungcono kombala, kanye nokuguqulwa kwamandla okumangalisayo, okwenza kube kuhle kakhulu kuzinhlelo zokusebenza ezibeka phambili ukusebenza kahle kanye nomklamo.
Isiphetho
Ngayinye yalezi zobuchwepheshe zamaseli elanga ezithuthukisiwe idlala indima ebalulekile ekuthuthukiseni ukusebenza kahle, ukunciphisa izindleko, kanye nokwandisa ububanzi bokusetshenziswa kwe-photovoltaics. Njengoba lobu buchwepheshe bukhula futhi bukhula, buzothuthukisa kakhulu ukusebenza kwelanga, busheshise ukushintshela emandleni ahlanzekile futhi bubhekane nezinselele zesimo sezulu.
