Amaphaneli Elanga e-HJT: Ukuphayona Ikusasa Lamandla Elanga
Cabanga ngezwe lapho amaphaneli elanga angabamba cishe yonke imisebe yokukhanya kwelanga, ayiguqule ibe amandla ahlanzekile, avuselelekayo ngokusebenza kahle okungenakuqhathaniswa. Siyakwamukela enkathini ye-Heterojunction Technology (HJT), intuthuko entsha ebeka amazinga amasha embonini ye-photovoltaic (PV). Ngesakhiwo sayo esiyingqayizivele kanye nokusebenza kwayo okuphezulu, i-HJT akuyona nje into entsha yezobuchwepheshe kodwa iyisibani sethemba lekusasa eliqhubekayo.
Umlingo Ongemuva Kobuchwepheshe be-HJT
I-HJT, efushanisiwe ngokuthi i-Heterojunction Technology, iyisimangaliso endaweni yamandla elanga. Ngokungafani namaphaneli elanga endabuko ancike ohlotsheni olulodwa lwe-silicon, amaphaneli e-HJT asebenzisa inhlanganisela eyinkimbinkimbi yezingqimba ze-silicon, ngayinye idlala indima ebalulekile ekusebenziseni amandla elanga.
1. Isendlalelo Esiphezulu: I-Amorphous Silicon – I-Light Catcher
Cabanga ngefilimu encane ye-silicon ethambile nethambile ebamba ukukhanya kwelanga kokuqala, iqala ukuguqulwa kokukhanya kube ugesi ngendlela emangalisayo.
2. Ungqimba Oluphakathi: I-Crystalline Silicon – I-Powerhouse
Ngaphansi kwesendlalelo esiphezulu kukhona i-silicon ekristalu, isithambisi sokukhanya esiqinile nesisebenza kahle. Lesi sendlalelo siyinhliziyo yephaneli ye-HJT, lapho iningi lokukhanya liguqulwa libe amandla kagesi.
3. Isendlalelo Esingezansi: I-Amorphous Silicon – I-Photon Hunter
Njengoba ukukhanya kuhlunga ngezingqimba ezingaphezulu, noma yimaphi ama-photon asele abanjwa ungqimba olungezansi lwe-silicon engaguquki. Lokhu kuqinisekisa ukuthi akukho msebe wokukhanya ochithekayo, okwandisa ukukhiqizwa kwamandla.
Indlela Amaphaneli Elanga e-HJT Asebenza Ngayo Umlingo Wawo
Umklamo onamaleya amaningi wamaphaneli e-HJT ufana nomculo wokukhanya ne-silicon. Lapho ukukhanya kwelanga kushaya iphaneli, ungqimba oluphezulu lwe-silicon engaguquki lumunca ukukhanya okuthile, lukhiqize ukushaja kukagesi kokuqala. Ungqimba oluphakathi lwe-silicon oluyikristalu luyathatha izintambo, luguqule ingxenye enkulu yokukhanya ibe amandla kagesi. Ekugcineni, ungqimba oluphansi lwe-silicon engaguquki lubamba ama-photon asele, lusunduze ukusebenza kahle kwephaneli liye ezindaweni ezintsha eziphakeme.
Ukusebenza Kahle: Igugu Lomqhele Lamaphaneli E-HJT
Amaphaneli e-HJT ayimpahla yasebukhosini emhlabeni welanga, aqhosha ngokusebenza kahle kokuguqulwa okunomona ngobuchwepheshe bendabuko. Ngenkathi amaphaneli e-PERC ephatha ukusebenza kahle okungaba ngu-20%, kanti amaphaneli e-TOPCon akhuphukela cishe ku-23%, amaphaneli e-HJT abusa kakhulu ngokusebenza kahle kohlangothi olulodwa okungu-26-27%. Nokho, i-showstopper yangempela yiphaneli ye-HJT enezinhlangothi ezimbili, ekhazimula ngokusebenza kahle okungaphezu kuka-30%. Lokhu kwenza i-HJT ibe ubuchwepheshe obusebenza kahle kakhulu okwamanje obukhanyisa imboni ye-PV.
Izithako Eziyingqayizivele Zamaphaneli Elanga e-HJT
1. Indlela Elula Yokukhiqiza
Ukwakha amaphaneli e-HJT kuyinto elula, ehilela izinyathelo ezine ezimbalwa kunokukhiqiza amaphaneli elanga endabuko. Lokhu akusheshisi nje kuphela inqubo yokukhiqiza kodwa futhi kunciphisa nezindleko.
2. Ukusebenza Kokuguqulwa Okungalingani
Ngenxa yesakhiwo sayo se-silicon esinezingqimba eziningi, amaphaneli e-HJT anikeza ukumuncwa kokukhanya okuphezulu kanye nokuguqulwa kwamandla, okudlula kakhulu ubuchwepheshe be-PERC kanye ne-TOPCon.
3. Isimangaliso Esinezinhlangothi Ezimbili
Amaphaneli e-HJT asebenza kahle kakhulu ekusethweni kwezinhlangothi ezimbili, lapho izinhlangothi zombili zephaneli zisebenza khona. Lokhu kugqama okunezinhlangothi ezimbili kuvumela ukukhishwa kwamandla amakhulu kusuka endaweni efanayo, okwenza i-intshi ngayinye ibalwe.
4. Iqhawe Lokushisa
Amaphaneli e-HJT ayachuma ezindaweni ezinokushisa okuphezulu, egcina ukusebenza kwawo kahle ngisho nalapho i-mercury ikhuphuka. Lokhu kuwenza abe mahle kakhulu ezindaweni ezinelanga nezishisayo lapho amanye amaphaneli angase ahluleke khona.
Uhambo Lwemakethe lwe-HJT kanye Nombono Wesikhathi Esizayo
Naphezu kokusebenza kwayo okuhle, ubuchwepheshe be-HJT okwamanje buthatha ingxenye encane yemakethe. I-TOPCon inesabelo semakethe esibalulekile esingu-70%, kuyilapho i-HJT ine-5% kuphela Izindleko eziphakeme zamaphaneli e-HJT, kusukela ku-$0.13 kuya ku-$0.20 nge-watt, uma kuqhathaniswa ne-$0.10 nge-watt engabizi kakhulu yamamojula wohlobo lwe-P nohlobo lwe-N, iyisici esibalulekile. Kodwa-ke, ikusasa liqhakazile nge-HJT njengoba intuthuko iqhubeka nokwehlisa izindleko, okwenza lobu buchwepheshe butholakale kalula.
Ikusasa Likhanya Kakhulu ne-HJT
Amaphaneli elanga e-HJT awawona nje isinyathelo sokuqhubekela phambili; ayisinyathelo esikhulu embonini ye-photovoltaic. Ngokukhiqiza kwawo okulula, ukusebenza kahle okuphezulu, kanye nokusebenza okuphezulu ngaphansi kwezimo ezahlukahlukene, amaphaneli e-HJT alungele ukuba yindinganiso yegolide yamandla elanga. Njengoba umhlaba uqhubeka nokwamukela amandla avuselelekayo, ubuchwepheshe be-HJT bukulungele ukuhola i-charge eya ekusaseni eliqhakazile nelizinzile.
Ngakho-ke, ngesikhathi esizayo lapho uzwa ukwamukelwa okufudumele kwelanga, khumbula i-symphony ethule yamaphaneli e-HJT, eguqula ngokungakhathali lokho kukhanya kube amandla anika amandla izimpilo zethu. Kuyo yonke imisebe, kunesithembiso sekusasa eliluhlaza, futhi i-HJT ilapha ukuze yenze leso sithembiso sibe ngokoqobo.
