PV Cell Technology Amathrendi

Ososayensi abayishumi baveze izindlela ezintsha zobuchwepheshe obukhulu be-PV cell eminyakeni emihlanu ezayo, esihlokweni sokufinyelela okuvulekile Iseli.

Nakuba umthamo we-PV ofakiwe emhlabeni wonke udlula i-terawatt engu-1 (1,000 GW), umnikelo welanga ekuphehlisweni kukagesi emhlabeni wonke uhlala uncane, abacwaningi bathi, ku-5% kuya ku-6%. Njengoba kunikezwe “isidingo esiphuthumayo” sokusebenzisa i-PV esikalini sama-terawatt amaningi eminyakeni engamashumi amabili ezayo ukuze kuncishiswe ukukhishwa kwesisi esibamba ukushisa, “Ukuqamba okusha kwedivayisi ye-PV kuthatha ukuphuthuma nomthelela omusha.”

Ucwaningo oluqhubekayo oluholela "ngisho nentuthuko encane" ekusebenzeni kahle, ukwethembeka nokusebenza kahle kokukhiqiza "kuzoba nemithelela emikhulu yesikhathi esizayo esikalini se-multi-TW," kusho abacwaningi, bephawula lezi zici zihlangana ukuze zenze "isiphakamiso senani esicindezelayo" sokuphehla amandla e-PV.

Ngenkathi i-crystalline silicon PV yayinesabelo semakethe esingu-95% ngo-2022, “ekusaseni lesikali se-terawatt” “ne-PV yonke indawo,” bathi ubuchwepheshe obuningi bungase buhambisane, noma buhlanganiswe, basho.

Ubuchwepheshe be-silicon PV olwaziwa nge-TOPCon (umhubhe we-oxide passivating contact), onesabelo semakethe esingu-23%, "uzonqoba" ukukhiqizwa kwe-PERC (i-passivated emitter neseli yangemuva) PV ngo-2025 futhi "kungenzeka kube ubuchwepheshe obukhethwayo bokukhiqiza amaseli amasha e-US," i-athikili ibikezela.

Amaseli e-Crystalline silicon PV asondela ekusebenzeni kahle kwethiyori ye-single-junction engu-29.4%, basho.

Ucwaningo lusadingeka, baphawula, ukuthuthukisa izinga lokushisa eliphezulu, indawo ekhethiwe yokudlula othintana nabo ezinhlangothini zombili zeseli ye-PV ("advanced TOPCon"), ukuthuthukisa ukucaca kanye nokusebenza koxhumana nabo be-heterojunction technology (HJT) ("i-HJT ethuthukisiwe"), kanye nokuhlanganisa ubuchwepheshe bakamuva be-HJT noma i-TOPCon obungafinyelela emuva (i-interface) ye-interface engafinyelela isakhiwo se-interface esisebenzayo 28% ngokunokwenzeka ngokushesha ngo-2025. "

Kodwa-ke njengoba kusondela umkhawulo wethiyori, "kwembulwa izindlela ezintsha ezimbalwa zokuwohloka, okubizwa ngokuthi ukucekelwa phansi okubangelwa umthwali, kanye nokukhubazeka okubonakalayo kuyembulwa," kusho abaphenyi.

Imboni "isebenzela ukunciphisa noma ukuqeda" ukusetshenziswa kwezinto eziyivelakancane njengesiliva ekwakhiweni kwemigqa yegridi kanye ne-indium esetshenziswa ku-transparent conductive oxides, kusho ababhali. Izinkampani eziningana ze-PV namalabhorethri ocwaningo zimemezele idizayini yeseli ye-HJT PV encishisiwe ukusetshenziswa kwe-idium "noma ngisho ne-indium-free" amaseli e-HJT.

Umthombo ovela pv umagazini

Umshwana wokuzihlangula: Ulwazi olubekwe ngenhla luhlinzekwa ngumagazini we-pv ngaphandle kwe-Chovm.com. I-Chovm.com ayenzi izethulo namawaranti mayelana nekhwalithi nokuthembeka komdayisi nemikhiqizo.
