Ngaphansi kwesu "le-dual carbon", imboni ye-photovoltaic (PV) yaseShayina ifinyelele emisha emangalisayo, ikhuthaza ukuthuthukiswa kobuchwepheshe bamaseli obusebenza kahle kakhulu kanye nezimo ezahlukahlukene zokusetshenziswa. Ngo-2024, umkhakha we-PV ubona ukwanda kobuchwepheshe obusezingeni eliphezulu njenge-HJT, BC, kanye ne-perovskite, okubonisa inkathi entsha yokuthuthuka kobuchwepheshe.
Ubuchwepheshe be-HJT
Ubuchwepheshe be-Heterojunction (HJT) bunikeza ukusebenza kahle okumangalisayo, ukukhiqizwa kwamandla amabili, ama-coefficient okushisa kwamandla aphansi, kanye nokuwohloka okuncishisiwe. Eminyakeni yamuva nje, ukuthuthuka kwezinto ezisetshenziswayo ezisezingeni eliphezulu kuye kwehlisa kakhulu izindleko. Isibonelo, ukuhlinzekwa okuzinzile kwe-KEEs kwe-paste yethusi embozwe ngesiliva kubhekane nezinkinga zezindleko, kuyilapho abaholi bemboni besebenzisa ubuchwepheshe obunelungelo lobunikazi njengamaseli e-0BB kanye nama-wafer e-silicon amancane kakhulu ekukhiqizeni ngobuningi. Abahlaziyi babikezela ukuthi ukukhula kwe-HJT kuzokwakha kabusha imboni ye-PV, kuthuthukise amandla futhi kuqinise ukuncintisana kwayo emhlabeni jikelele.
Ubuchwepheshe be-BC
Amaseli e-Back Contact (BC) abhekwa njengesici esivelele sokusebenza kahle kwe-silicon ekristali. Umklamo wawo wangaphambili ongenagridi uthuthukisa kokubili ubuhle kanye nokukhishwa kwamandla. Ubuchwepheshe be-BC buhlangana nezinye izinhlobo zamaseli njenge-TOPCon kanye ne-HJT, okuthuthukisa ukusebenza kahle. Abaholi bemakethe abanjengo-LONGi kanye no-Aiko baqalise imikhiqizo ye-BC, kanti ochwepheshe babikezela ukuthi isabelo semakethe ye-BC sizofinyelela ku-30-40%. Lobu buchwepheshe bukulungele ukusekela izinhlelo zokusebenza ezahlukahlukene kanye nokukhula kwemboni okusimeme.
Ubuchwepheshe bePerovskite
I-Perovskite idunyiswa njengomholi wobuchwepheshe be-PV besizukulwane sesithathu, inezinga eliphezulu lokusebenza kahle, ukusebenza okuqinile kokukhanya okuphansi, kanye nezinqubo ezilula. Izakhiwo zayo ezihlangene zithembisa ukusebenza kahle kokuguqulwa okungaphezu kuka-45%. Intuthuko yakamuva ekuzinzeni iphawula ingqophamlando ebalulekile. Ngo-2027, i-perovskite kulindeleke ukuthi ifinyelele ekukhiqizweni okukhulu, ivule amandla kuyo yonke imikhakha efana ne-IoT, ama-EV, kanye nezindiza, ngenkathi isheshisa ukushintshela emandleni avuselelekayo.
Lobu buchwepheshe obuthuthukisiwe bumelela ikusasa elithembisayo embonini ye-PV, bunikeza izindlela ezintsha zentuthuko esimeme nesezingeni eliphezulu.
