ʻenehana Heterojunction (HJT) Hōʻike nā Panel Solar i kahi holomua nui i ka ikehu lā. Hoʻohui kēia ʻenehana hou i ka monocrystalline a me ka amorphous silicon layers e hoʻonui ai i ka hana a me ka lōʻihi. Hiki i nā panela solar HJT ke hoʻokō i ka pono a hiki i ka 25%, ʻoi aku ka kiʻekiʻe ma mua o nā ʻano panela solar kuʻuna. No ka laʻana, hāʻawi ʻo Tongwei's HJT panel 715 W o ka mana me 23.0% maikaʻi . Hōʻike kēia mau panela i kahi hoʻolālā ʻaoʻao ʻelua e hiki ai iā lākou ke hana i ka mana mai nā ʻaoʻao ʻelua, e hoʻonui i ka hopu ʻana o ka lā a me ka hana ikehu. He koho maikaʻi loa ka HJT solar panels no ka hoʻohana ʻana i ka ikehu hou ʻoiai e hōʻoia ana i ka hilinaʻi i ka manawa.
Hoʻohana ka HJT solar panels i ʻelua papa silika e hana ʻoi aku ka maikaʻi, a hiki i ka 25% pono.
Hiki i kēia mau paneli ke hōʻiliʻili i ka lā mai nā ʻaoʻao ʻelua e hoʻonui i ka ikehu.

Ke makemake nei ka poʻe i ka ikehu maʻemaʻe hou aʻe, e lilo paha nā panela HJT i mea kaulana loa i ka ʻoihana lā.
Hoʻohana ka ʻenehana Heterojunction i ʻelua ʻano silika— monocrystalline a me amorphous —e hana i nā pūnaewele lā. Hoʻonui kēia hoʻolālā akamai i ka hoʻololi ʻana i ka ikehu ma ka hoʻohui ʻana i nā hiʻohiʻona maikaʻi loa o nā mea ʻelua. He mea maikaʻi ke silikona monocrystalline no ka hana ʻana i ka uila, ʻoiai ʻo ka silikona amorphous e hōʻemi ana i ka pau ʻana o ka ikehu a hoʻomoʻi i ka māmā. Hoʻohui pū lākou i nā panela solar e hana maikaʻi a lōʻihi.
Ua puni kēia ʻenehana no nā makahiki he mau makahiki. Ua hana mua ia i ka 1970s a lilo i mea kaulana ma hope o Sanyo i hoʻopaʻa ʻia ma 1997. I ka pau ʻana o ka patent ma 2010, hoʻomaka hou nā hui e hoʻohana iā ia, e alakaʻi ana i nā hoʻomaikaʻi nui. I kēia lā, ʻike ʻia kēia mau panela solar no kā lākou hana kiʻekiʻe a manaʻo ʻia e alakaʻi i ka mākeke solar.
Hoʻohana ka ʻenehana Heterojunction i nā papa e hoʻohuli i ka lā i uila. He hana ko kēlā me kēia papa. ʻO ka mua, paʻi ka lā i ka papa luna silikona amorphous , kahi e hoʻomoʻa a hōʻike i ka mālamalama i ka papa silikona crystalline . Hoʻololi ka papa silikona crystalline i ka hapa nui o ka lā i uila. ʻO nā kukui koena e hele i ka papa silika amorphous lalo , no laila, liʻiliʻi loa ka ikehu e pau.
Eia ka hana a kēlā me kēia papa i nā panela solar HJT:

ʻO kēia hoʻolālā e hana i nā panela i ka maikaʻi a me ka hilinaʻi, ʻoiai i nā ʻano kukui like ʻole.
ʻO ka ʻāpana silika crystalline ka ʻāpana nui o nā cell solar HJT. Hoʻololi ia i ka lā i uila me ka maikaʻi loa. Hōʻike nā hōʻike hiki ke piʻi i ka 26.5% ka maikaʻi ke hoʻopili ʻia me nā ʻano holomua e like me interdigitated back contact (IBC). Ke hoʻohana nei i nā ʻāpana lahilahi o ke silika, e pili ana i ka 10 μm mānoanoa , kōkua hoʻi e hoʻohaʻahaʻa i nā kumukūʻai i ka hoʻomaikaʻi ʻana i ka hana.
ʻO nā papa silika amorphous e kōkua i ka hana ʻoi aku ka maikaʻi o nā panela solar HJT. Ke hana nei kēia mau papa me ka silika crystalline e hōʻemi i ka nalowale o ka ikehu a e hoʻomoʻi i ka māmā. Hoʻopaʻa lākou i nā kiʻi paʻi i pakele, e kōkua ana i ka hana ʻana o ka panel i kāna maikaʻi loa. Hiki i kēia hoʻolālā ke kōkua i nā panela e hana maikaʻi i ka mālamalama liʻiliʻi.
ʻO ka papa indium tin oxide kahi papa kuhikuhi a maopopo i nā panela HJT. Hāʻawi ia i ka hele ʻana o ka lā i ka wā e lawe ana i ka uila. Hoʻemi kēia ʻāpana i ke kūpaʻa uila a hoʻonui i ka hoʻouna ʻana i ka māmā, e mālama pono ana i nā panela.

He 30 makahiki ka lōʻihi o nā panela HJT. Nalo lākou i ka 0.56% pono i kēlā me kēia makahiki, ʻoi aku ka lohi ma mua o nā panela maʻamau. ʻO ia ke kumu e hoʻomau lākou i ka ikehu no ka manawa lōʻihi, mālama kālā i nā makahiki.
ʻAe, maikaʻi lākou i ka mālamalama haʻahaʻa. ʻOi aku ka nui o ka lā o ko lākou mau papa kūikawā, ʻoiai i nā lā ao a i ʻole i ke kakahiaka a me ke ahiahi. Kōkua kēia iā lākou e hoʻomau i ka ikehu i ka lā a pau, ʻaʻole pili i ke aniau.
I kēia manawa, ʻoi aku ka nui o ke kumukūʻai no ka hana ʻana ma mua o nā panela maʻamau. Akā ʻo kā lākou hana maʻalahi e hoʻemi koke i nā kumukūʻai. ʻO kā lākou hana kiʻekiʻe a me ke ola lōʻihi e mālama i ke kālā i ka manawa, ke kaulike ʻana i ke kumu kūʻai.
ʻO ka Bifaciality ke ʻano o ka panel hiki ke hoʻohana i ka lā mai nā ʻaoʻao ʻelua. Loaʻa i nā panela HJT a hiki i ka 95% bifaciality, e ʻae iā lākou e hana i ka mana hou mai ka mālamalama i ʻike ʻia. He mea pono loa keia ma na kula akea a me na wahi hau.
ʻOi aku ka maikaʻi o nā panela HJT ma mua o nā panela PERC ma nā ʻano he nui. Hoʻololi lākou i ka lā i ka ikehu (a hiki i 25%) a lōʻihi ka lōʻihi. ʻO kā lākou hoʻolālā ʻaoʻao ʻelua e hoʻonui i ka mana, e hoʻolilo iā lākou i koho kiʻekiʻe no ka ikehu lā.
ʻAe, pili kaiaola lākou. ʻO ka hoʻohana ʻana iā lākou e hoʻohana i ka ikehu liʻiliʻi a hana i nā mea liʻiliʻi. ʻO ko lākou ola lōʻihi a me ka maikaʻi kiʻekiʻe e hōʻemi i ka ʻōpala, e hoʻolilo iā lākou i koho ʻōmaʻomaʻo no ka ikehu maʻemaʻe.
