Boemo ba libeteri tsa mofuta oa N-TOPCon bo tobane le mathata a kang ho sitoa ho koahela maemo a hajoale le tlhoko ea ho ntlafatsa ts'ebeliso ea maemo. Pampiri ena e tla etsa lipatlisiso le tlhahlobo mabapi le maemo a li-betri tsa mofuta oa N-TOPCon, le ho fana ka litlhahiso bakeng sa maemo.Boemo ba nts'etsopele ea theknoloji ea sele ea n-mofuta oa TOPConSebopeho sa lisebelisoa tsa motheo tsa silicon tsa mofuta oa p tse sebelisoang liseleng tse tloaelehileng tsa photovoltaic ke n + pp +, sebaka se amohelang leseli ke n+ holim 'me ho sebelisoa ha phosphorous diffusion ho etsa emitter.Ho na le mefuta e 'meli e meholo ea homojunction photovoltaic cell structures bakeng sa lisebelisoa tsa motheo tsa silicon tsa mofuta oa n, e' ngoe ke n+np+, 'me e' ngoe ke p+nn+.Ha e bapisoa le silicon ea mofuta oa p, silicon ea mofuta oa n e na le bophelo bo betere ba bajari ba batho ba fokolang, ho thefuleha ho tlase, le bokhoni bo matla ba ho sebetsa hantle.Sele ea n-mofuta oa mahlakore a mabeli e entsoeng ka silicon ea mofuta oa n e na le melemo ea ts'ebetso e phahameng, karabelo e ntle ea khanya e tlase, mocheso o tlase oa mocheso, le ho hlahisa matla a mabeli a mahlakoreng a mabeli.Ha litlhoko tsa indasteri bakeng sa katleho ea phetoho ea photoelectric ea lisele tsa photovoltaic li ntse li eketseha, lisele tsa photovoltaic tse nang le matla a phahameng a n-type tse kang TOPCon, HJT, le IBC li tla lula butle-butle 'marakeng.Ho ea ka 2021 International Photovoltaic Roadmap (ITRPV) theknoloji ea indasteri ea photovoltaic ea lefats'e le ponelopele ea 'maraka, lisele tsa mofuta oa n li emela theknoloji ea nakong e tlang le tataiso ea nts'etsopele ea mebaraka ea lisele tsa photovoltaic lapeng le kantle ho naha.Har'a litsela tsa tekheniki tsa mefuta e meraro ea libeteri tsa mofuta oa n, libeteri tsa mofuta oa N-TOPCon li fetohile tsela ea theknoloji e nang le tekanyo e kholo ka ho fetisisa ea indasteri ka lebaka la melemo ea bona ea tekanyo e phahameng ea tšebeliso ea lisebelisoa tse teng le katleho e phahameng ea phetoho.
Hajoale, libeteri tsa mofuta oa N-TOPCon indastering ka kakaretso li lokiselitsoe ho latela thekenoloji ea LPCVD (mouoane o tlase oa khatello ea phase ea lik'hemik'hale), e nang le mekhoa e mengata, katleho le lihlahisoa li thibetsoe, 'me lisebelisoa li itšetlehile ka thepa e tsoang linaheng tse ling. E hloka ho ntlafatsoa. Tlhahiso e kholo ea lisele tsa TOPCon tsa mofuta oa n-type li tobane le mathata a theknoloji a kang litšenyehelo tse phahameng tsa tlhahiso, mokhoa o rarahaneng, tekanyo e tlaase ea lihlahisoa, le katleho e sa lekaneng ea phetoho.Indasteri e entse boiteko bo bongata ba ho ntlafatsa theknoloji ea lisele tsa TOPCon tsa mofuta oa n. Har'a tsona, thekenoloji ea in-situ doped polysilicon layer e sebelisoa ka mokhoa o le mong oa ts'ebetso ea tunneling oxide layer le doped polysilicon (n + -polySi) lera ntle le ho phuthela plating;Electrode ea tšepe ea n-mofuta oa TOPCon betri e lokiselitsoe ka ho sebelisa theknoloji e ncha ea ho kopanya pente ea aluminium le pente ea silevera, e fokotsang litšenyehelo le ho ntlafatsa ho hanyetsa ho kopana; amohela ka pele khetha emitter sebopeho le ka morao multi-lara tunneling passivation kopana sebopeho sebopeho theknoloji.Lintlafatso tsena tsa theknoloji le ts'ebetso ea ts'ebetso li entse tlatsetso e itseng ho nts'etsopele ea lisele tsa TOPCon tsa mofuta oa n.Patlisiso mabapi le maemo a betri ea mofuta oa N-TOPConHo na le liphapang tse ling tsa tekheniki lipakeng tsa lisele tsa TOPCon tsa mofuta oa n-mofuta le lisele tse tloaelehileng tsa p-type photovoltaic, 'me kahlolo ea lisele tsa photovoltaic' marakeng e ipapisitse le litekanyetso tse tloaelehileng tsa betri, 'me ha ho na tlhokahalo e hlakileng ea mofuta oa n-type photovoltaic cell. .Seleng ea TOPCon ea mofuta oa n e na le litšobotsi tsa ho fokotsa mocheso o tlaase, mocheso o tlaase oa mocheso, bokhoni bo phahameng, coefficient e phahameng ea bifacial, matla a ho bula a phahameng, joalo-joalo E fapane le lisele tse tloaelehileng tsa photovoltaic ho latela litekanyetso.
