I nā makahiki i hala iho nei, me ka hoʻomohala ʻana a me ka hoʻohana ʻana i nā ʻenehana hou, nā kaʻina hana hou a me nā hale hou o nā cell photovoltaic, ua ulu wikiwiki ka ʻoihana photovoltaic cell. Ma ke ʻano he ʻenehana koʻikoʻi e kākoʻo ana i ka hoʻomohala ʻana i ka ikehu hou a me nā grids akamai, ua lilo nā ʻano n-type i wahi wela i ka hoʻomohala ʻana i nā ʻoihana honua.
No ka mea, ʻo ka n-type tunneling oxide layer passivation contact photovoltaic cell (i kapa ʻia ʻo "n-type TOPCon cell") ka hana pono o ka hoʻomaikaʻi maikaʻi ʻana i ka hoʻohālikelike ʻia me nā cell photovoltaic maʻamau, me ka piʻi ʻana o ke kumukūʻai hiki ke mālama ʻia a me ka hoʻololi ʻana i nā mea pono. ka n-type TOPCon cell ʻO ka hoʻonui hou ʻana i ka mana hana hale i lilo i alakaʻi hoʻomohala nui o nā kiʻi photovoltaic kiʻekiʻe.
ʻO ka hoʻohālikelike ʻana i nā ʻāpana n-type TOPCon e kū nei i nā pilikia e like me ka hiki ʻole ke uhi i nā kūlana o kēia manawa a me ka pono e hoʻomaikaʻi i ka hoʻohana ʻana o nā kūlana. E alakaʻi kēia pepa i ka noiʻi a me ka nānā ʻana i ka hoʻohālikelike ʻana i nā ʻano pākahi TOPCon n-type, a hāʻawi i nā manaʻo no ka hoʻohālikelike ʻana.Ke kūlana hoʻomohala o n-type TOPCon cell technologyʻO ke ʻano o ka p-type silicon base material i hoʻohana ʻia i nā cell photovoltaic maʻamau ʻo n + pp +, ʻo ka ʻili e loaʻa i ka mālamalama he n + ili, a hoʻohana ʻia ka diffusion phosphorous e hana i ka emitter.ʻElua ʻano nui o ka homojunction photovoltaic cell structures no n-type silicon base material, hoʻokahi n+np+, a ʻo kekahi p+nn+.Ke hoʻohālikelike ʻia me ka silika p-type, ʻoi aku ka maikaʻi o ka silicon n-type i ke ola o ka mea lawe liʻiliʻi, haʻahaʻa haʻahaʻa, a ʻoi aku ka maikaʻi.ʻO ka n-type pālua ʻaoʻao i hana ʻia me ka n-type silicon he mau mea maikaʻi o ka hana kiʻekiʻe, ka pane haʻahaʻa haʻahaʻa haʻahaʻa maikaʻi, ka helu haʻahaʻa haʻahaʻa, a ʻoi aku ka mana o nā ʻaoʻao ʻelua.Ke hoʻomau nei nā koi o ka ʻoihana no ka hoʻololi ʻana i ka photoelectric o nā cell photovoltaic, ʻo n-type high-efficiency photovoltaic cell e like me TOPCon, HJT, a me IBC e noho mālie i ka mākeke e hiki mai ana.Wahi a ka 2021 International Photovoltaic Roadmap (ITRPV) ka ʻenehana ʻenehana photovoltaic honua a me ka wānana mākeke, nā ʻano n-type cell e hōʻike ana i ka ʻenehana e hiki mai ana a me ka alakaʻi hoʻomohala mākeke o nā cell photovoltaic ma ka home a ma waho.Ma waena o nā ala ʻenehana o nā ʻano pākahi n-type ʻekolu, ua lilo nā pihi n-type TOPCon i ke ala ʻenehana me ka nui o ka ʻoihana ʻoihana ma muli o kā lākou pono o ka hoʻohana kiʻekiʻe o nā mea hana i kēia manawa a me ka hoʻololi kiʻekiʻe.
I kēia manawa, hoʻomākaukau maʻamau nā pākaʻi n-type TOPCon i ka ʻoihana ma muli o ka ʻenehana LPCVD (low-pressure vapor-phase chemical deposition), nona nā kaʻina hana he nui, ua kaupalena ʻia ka pono a me nā hua, a hilinaʻi nā mea hana i ka lawe ʻana mai. Pono e hoʻomaikaʻi ʻia. ʻO ka hana nui o n-type TOPCon cell e kū nei i nā pilikia ʻenehana e like me ke kumukūʻai hana kiʻekiʻe, ke kaʻina hana paʻakikī, ka haʻahaʻa haʻahaʻa, a me ka lawa ʻole o ka hoʻololi ʻana.Ua hana ka ʻoihana i nā hoʻāʻo he nui e hoʻomaikaʻi i ka ʻenehana o n-type TOPCon cell. Ma waena o lākou, ua hoʻohana ʻia ka ʻenehana papa polysilicon doped i loko o ka deposition hoʻokahi-kaʻina o ka papa tunneling oxide a me ka papa polysilicon (n + -polySi) doped me ka ʻole o ka uhi ʻana i ka plating;Hoʻomākaukau ʻia ka electrode metala o ka pā uila n-type TOPCon ma ka hoʻohana ʻana i ka ʻenehana hou o ka hui ʻana i ka alumini paʻi a me ka paʻi kālā, e hoʻemi ana i ke kumukūʻai a hoʻomaikaʻi i ke kūpaʻa pili; hoʻohana i ka ʻōnaehana emitter koho mua a me ka ʻenehana hoʻopili hoʻopili passivation hoʻopili hope.ʻO kēia mau hoʻonui ʻenehana a me ka loiloi kaʻina hana i hāʻawi i kekahi mau haʻawina i ka hoʻomohala ʻana i nā pūnaewele n-type TOPCon.E noiʻi e pili ana i ka hoʻohālikelike ʻana i ka pākaukau n-type TOPConAia kekahi mau ʻokoʻa ʻenehana ma waena o n-type TOPCon cell a me ka p-type photovoltaic cell maʻamau, a ʻo ka hoʻoholo ʻana o nā pūnaewele photovoltaic i ka mākeke e pili ana i nā kūlana pākahi maʻamau o kēia manawa, a ʻaʻohe koi maʻamau maʻamau no nā cell photovoltaic n-type. .ʻO ka n-type TOPCon cell nā hiʻohiʻona o ka haʻahaʻa haʻahaʻa, haʻahaʻa haʻahaʻa haʻahaʻa, kiʻekiʻe kiʻekiʻe, kiʻekiʻe bifacial coefficient, kiʻekiʻe wehe uila, a me nā mea ʻē aʻe i nā cell photovoltaic maʻamau e pili ana i nā kūlana.
E hoʻomaka ana kēia ʻāpana mai ka hoʻoholo ʻana i nā hōʻailona maʻamau o ka pākaukau n-type TOPCon, e hoʻokō i ka hōʻoia e pili ana i ka curvature, ka ikaika tensile electrode, ka hilinaʻi, a me ka hana attenuation i hoʻokumu ʻia i ka māmā, a kūkākūkā i nā hopena hōʻoia.Ka hoʻoholoʻana i nā hōʻailona maʻamauHoʻokumu ʻia nā cell photovoltaic maʻamau i ka huahana maʻamau GB/T29195-2012 "General Specifications for Ground-Used Crystalline Silicon Solar Cells", e koi pono ana i nā ʻāpana hiʻohiʻona o nā cell photovoltaic.Ma muli o nā koi o GB / T29195-2012, i hui pū ʻia me nā hiʻohiʻona ʻenehana o n-type TOPCon batteries, ua hoʻokō ʻia ka loiloi i kēlā me kēia mea.E nānā i ka Papa 1, ʻano like n-type TOPCon batteries me ka mea maʻamau i ka nui a me ka helehelena;
Papa 1 Ka hoohalike ana ma waena o n-type TOPCon pākahiko a me GB/T29195-2012 koi.
Ma nā ʻōlelo o nā ʻāpana hana uila a me ka coefficient mahana, ua hana ʻia nā hoʻokolohua e like me IEC60904-1 a me IEC61853-2, a ua kūlike nā ʻano hoʻāʻo me nā pihi maʻamau; ʻokoʻa nā koi no nā waiwai mechanical mai nā ʻano pākahi maʻamau e pili ana i ka degere bending a me ka ikaika tensile electrode.Eia kekahi, e like me ke kaiapuni noi maoli o ka huahana, ua hoʻohui ʻia kahi hoʻāʻo wela wela ma ke ʻano he koi hilinaʻi.Ma muli o ka nānā ʻana i luna, ua hoʻokō ʻia nā hoʻokolohua e hōʻoia i nā waiwai mechanical a me ka hilinaʻi o nā ʻano pā TOPCon n-type.Ua koho ʻia nā huahana cell photovoltaic mai nā mea hana like ʻole me ke ala ʻenehana like e like me nā laʻana hoʻokolohua. Hāʻawi ʻia nā laʻana e Taizhou Jolywood Optoelectronics Technology Co., Ltd.Ua hoʻokō ʻia ka hoʻokolohua ma nā keʻena laboratories ʻaoʻao ʻekolu a me nā hale hana ʻoihana, a ua hoʻāʻo ʻia a hōʻoia ʻia nā ʻāpana e like me ke degere bending a me ka ikaika tensile electrode, ka hoʻāʻo ʻana o ka wela wela a me ka hoʻāʻo wela wela, a ua hoʻāʻo ʻia a hōʻoia ʻia ka hana attenuation mua.Hōʻoiaʻiʻo i nā ʻano Mechanical o nā Pūnaewele PhotovoltaicUa ho'āʻo pololei ʻia ka degere bending a me ka ikaika tensile electrode i nā ʻano mechanical o nā ʻano pākahi TOPCon n-type ma ka pepa pākaukau ponoʻī, a penei ka hōʻoia ʻana o ke ʻano hoʻāʻo.ʻO ka curvature e pili ana i ka ʻokoʻa ma waena o ke kiko waena o ka ʻili waena o ka hāpana i hoʻāʻo ʻia a me ka mokulele kuhikuhi o ka ʻili waena. He hōʻailona koʻikoʻi ia e loiloi i ka palahalaha o ka pā ma lalo o ke koʻikoʻi ma o ka hoʻāʻo ʻana i ka deformation kulou o ka cell photovoltaic.ʻO kāna ʻano hoʻāʻo mua e ana i ka mamao mai ke kikowaena o ka wafer a i kahi mokulele kuhikuhi me ka hoʻohana ʻana i kahi hōʻailona hoʻoneʻe haʻahaʻa haʻahaʻa.Hāʻawi ʻo Jolywood Optoelectronics a me Xiʻan State Power Investment i 20 mau ʻāpana M10 nui n-type TOPCon pākahi. Ua ʻoi aku ka maikaʻi o ka palahalaha o ka ʻili ma mua o 0.01mm, a ua hoʻāʻo ʻia ka curvature pākaukau me kahi mea ana me ka hoʻonā ʻoi aku ma mua o 0.01mm.Hoʻokō ʻia ka hoʻāʻo ʻana o ka pilahi e like me nā ʻōlelo o 4.2.1 ma GB/T29195-2012.Hōʻike ʻia nā hopena hōʻike ma ka Papa 2.
Papa 2 Ke kulou ana i na hopena hoao o n-type TOPCon cell
Pono nā kūlana hoʻomalu kūloko o Jolywood a me Xiʻan State Power Investment ʻaʻole ʻoi aku ke kiʻekiʻe o ka piko ma mua o 0.1mm. E like me ka nānā ʻana o nā hopena hoʻāʻo laʻana, ʻo ka awelika kuʻekuʻe o Jolywood Optoelectronics a me Xiʻan State Power Investment ʻo 0.056mm a me 0.053mm. ʻO nā helu kiʻekiʻe he 0.08mm a me 0.10mm.Wahi a nā hopena o ka hōʻoia hōʻoia, ʻaʻole i ʻoi aku ke kiʻekiʻe o ka curvature o ke ʻano n-type TOPCon ma mua o 0.1mm.Electrode tensile ikaika hōʻoia hōʻoiaHoʻopili ʻia ka lipine metala i ka uwea mānoanoa o ke kelepona photovoltaic ma o ke kuʻi ʻana e hana i ke au. Pono e hoʻopili paʻa ʻia ka lipine solder a me ka electrode e hōʻemi i ke kūpaʻa hoʻopili a hōʻoia i ka pono o ka conduction o kēia manawa.No kēia kumu, hiki i ka hoʻāʻo ʻana i ka ikaika tensile electrode ma ka uea grid o ka pākaukau ke loiloi i ka weldability electrode a me ka maikaʻi o ka welding o ka pākaukau, ʻo ia ke ʻano hoʻāʻo maʻamau no ka ikaika adhesion o ka mīkini pā uila photovoltaic.<section style="margin: 0px 0px 16px;padding: 0px;outline
