Kodwa-ke, ngenxa yenkinga yenqubo yokulungiselela, ukusebenza kahle kwamamojula amnyama kuphansi kunalokho kwamamojula we-PERC, ngenkathi i-IBC "yemvelo enhle" i-IB ayinayo inkinga enjalo. Inokubukeka okuhle nokuguqulwa okuphezulu okuphezulu, ngakho-ke ibala elibanzi lesi simo kanye namandla opriyamu anamandla womkhiqizo.
Inqubo yokukhiqiza ivuthiwe, kepha ubunzima bobuchwepheshe buphakeme
Njengoba i-IBC inokuguqulwa okuphezulu okuguqukayo kanye nezinzuzo zezomnotho, kungani zimbalwa kakhulu izinkampani ezithumela i-IBC? Njengoba kushiwo ngenhla, yizinkampani kuphela ezikwazi kahle inqubo yokukhiqiza ye-IBC engaba nezindleko ngokufana okufana ne-PERC. Ngakho-ke, inqubo yokukhiqiza eyinkimbinkimbi, ikakhulukazi ubukhona bezinhlobo eziningi zezinqubo ze-semiconductor, yisizathu esiyisisekelo se- "Clustering" yayo engaphansi.
Ngomqondo wendabuko, i-IBC ikakhulukazi inemizila emithathu yenqubo: enye inqubo ye-Classic IBC emelelwa yi-ISFH (TBC ingezwe elifanayo njengoba kunjalo), kanti nokwesithathu kumelwe ngenqubo kaKaneka HBC. Indlela yobuchwepheshe be-ABC ye-AiXU ingabhekwa njengendlela yesine yezobuchwepheshe.
Ngokombono wokuvuthwa kwenqubo yokukhiqiza, i-IBC ye-Classic isivele izuze ukukhiqizwa kwabantu abaningi. Imininingwane ikhombisa ukuthi ukushona kwelanga kuthumele izingcezu eziyizigidi eziyizinkulungwane ezingama-3.5; I-ABC izofeza isilinganiselo sokukhiqizwa ngobuningi be-6.5gW kwikota yesithathu yalo nyaka. Izingxenye zochungechunge lwe- "Black Hole" lobuchwepheshe. Ukukhuluma, ubuchwepheshe be-TBC ne-HBC abuvuthiwe ngokwanele, futhi kuzothatha isikhathi ukubona ukuhweba.
Ethize kwinqubo yokukhiqiza, ushintsho olukhulu lwe-IBC uma kuqhathaniswa ne-perc, i-TopCon, ne-HJT lilele ekucushweni kwe-electrode yasemuva, okungukuthi, ukwakheka kwesifunda esihlangene se-P + kanye ne-N +, okubuye kube yisihluthulelo sokuthinta ukusebenza kwebhethri . Enqubweni yokukhiqiza ye-IBC ye-Classic, ukucushwa kwe-electrode yangemuva kufaka phakathi izindlela ezintathu: Ukuphrinta kwesikrini, ukufakwa kwe-Ion, okuholela ezinkambisweni ezintathu ezihlukile, futhi umzila ngamunye ongezansi uhambelana nezinqubo eziningi ezingaba ngu-14 Izinyathelo, izinyathelo eziyi-12 nezinyathelo eziyi-9.
Imininingwane ikhombisa ukuthi yize ukuphrinta kwesikrini nobuchwepheshe obuvuthiwe bubukeka bulula ebusweni, linezinzuzo zezindleko ezibalulekile. Kodwa-ke, ngoba kulula ukudala iziphambeko ebusweni bebhethri, umphumela we-doping kunzima ukulawula, nokunyathelisa okuningi kwesikrini nezinqubo eziqondile zokuqondanisa ziyadingeka, ngaleyo ndlela zikhulisa ubunzima bezinqubo kanye nezindleko zokukhiqiza. I-Laser etching inezinzuzo zezinhlobo ezi-doping ezi-doping eziphansi nezilawulayo, kepha inqubo iyinkimbinkimbi futhi inzima. I-Ion Infantation inezimpawu zokulawula okuphezulu okuphezulu nokufana okuhle, kepha imishini yayo iyabiza futhi kulula ukudala ukulimala kwe-lattice.
Ebhekisa kwinqubo yokukhiqiza ye-ABC ye-AIXU, ikwamukela kakhulu indlela ye-laser etching, futhi inqubo yokukhiqiza inezinyathelo eziningi njengezingu-14. Ngokwemininingwane evezwe yinkampani emhlanganweni wokushintshaniswa kokusebenza, inani lesivuno sokukhiqiza iningi le-ABC lingama-95% kuphela, eliphansi kakhulu kune-98% ye-PERC ne-HJT. Kufanele wazi ukuthi i-AIXU ngumkhiqizi weseli ochwepheshe ngokuqongelelwa kwezobuchwepheshe okuphezulu, futhi ivolumu yayo yokuthumela imigomo yesibili emhlabeni unyaka wonke. Lokhu futhi kufakazela ngokuqondile ukuthi ubunzima benqubo yokukhiqiza ye-IBC buphezulu.
Enye yezindlela zobuchwepheshe ezilandelayo zeTopCon ne-HJT
Yize inqubo yokukhiqiza ye-IBC inzima, izici zayo zohlobo lwesiteji esiphakeme kakhulu umkhawulo wokuguqulwa okuphezulu, lapho ugcina ukuncintisana kwempilo yezobuchwepheshe, ngenkathi kunciphisa ukuncintisana kwemakethe kwamabhizinisi, kunganciphisa nokusebenza okubangelwa yi-technilogical iteration . ubungozi. Ikakhulu, kufakwa ngeTopCon, HJT, kanye ne-Perovskite ukwakha ibhethri le-tandem elinokuguqulwa okuphezulu kubhekwa ngokungemthetho komkhakha njengenye yezindlela zobuchwepheshe ezijwayelekile ngokuzayo. Ngakho-ke, i-IBC kungenzeka ibe ngesinye sezindlela zobuchwepheshe ezilandelayo zamakamu weTopcon nama-HJT. Njengamanje, izinkampani eziningi ziveze ukuthi zenza ucwaningo lwezobuchwepheshe olufanele.
Ngokukhethekile, i-TBC eyakhiwa yi-superposition yeTopCon ne-IBC isebenzisa ubuchwepheshe bePolo nge-IBC ngaphandle kwesihlangu ngaphambili, okuvuselela umphumela wokudlula ngaphandle kokulahlekelwa ukusebenza kahle kwamanje, ngaleyo ndlela kuthuthukise ukusebenza kahle kwe-PhotoElectric.
