Raws li qhov kev thov rau lub zog rov ua dua tshiab txuas ntxiv mus, kev lag luam hnub ci tau ua tiav kev vam meej tseem ceeb hauv kev siv tshuab hnub ci vaj huam sib luag. Cov kev tsim kho tshiab tshiab suav nrog PERC, HJT thiab TOPCON lub hnub ci vaj huam sib luag, txhua tus muaj cov yam ntxwv thiab cov txiaj ntsig tshwj xeeb. Kev nkag siab txog qhov sib txawv ntawm cov thev naus laus zis no yog qhov tseem ceeb rau cov neeg siv khoom thiab cov lag luam uas tab tom nrhiav kev nqis peev rau hauv cov kev daws teeb meem hnub ci.
PERC, uas sawv cev rau Passivated Emitter thiab Rear Cell, yog ib hom vaj huam sib luag hnub ci uas tau nrov npe nyob rau xyoo tas los no vim nws ua haujlwm tau zoo dua thiab ua tau zoo dua. Lub ntsiab lus tseem ceeb ntawm PERC vaj huam sib luag hnub ci yog ntxiv ib txheej passivation rau sab nraub qaum ntawm lub cell, uas txo cov electron recombination thiab ua rau tag nrho cov txiaj ntsig ntawm lub vaj huam sib luag zoo dua. Cov thev naus laus zis no ua rau PERC vaj huam sib luag ua tiav cov txiaj ntsig zoo dua, ua rau lawv yog qhov kev xaiv zoo rau kev siv hauv tsev thiab kev lag luam.
HJT (Heterojunction Technology), ntawm qhov tod tes, yog lwm lub thev naus laus zis hnub ci uas tsim kev kub ntxhov hauv kev lag luam. Cov vaj huam sib luag Heterojunction muaj cov txheej nyias nyias ntawm amorphous silicon rau ob sab ntawm lub cell crystalline silicon, uas pab txo qhov poob hluav taws xob thiab ua kom muaj txiaj ntsig zoo dua. Qhov kev tsim tshiab no ua rau HJT panels xa cov zis hluav taws xob siab dua thiab ua tau zoo dua hauv cov xwm txheej tsawg, ua rau lawv yog qhov kev xaiv nrov hauv thaj chaw uas muaj hnub ci tsawg dua lossis cov qauv huab cua hloov pauv.
TOPCON, luv rau Tunnel Oxide Passivated Contact, yog lwm lub thev naus laus zis hnub ci uas tau txais kev saib xyuas rau nws qhov kev ua tau zoo tshaj plaws. TOPCON cov vaj huam sib luag muaj cov qauv tshwj xeeb nrog cov neeg sib cuag passivated ntawm pem hauv ntej thiab nraub qaum kom txo qhov poob zog thiab ua kom cov cell ua haujlwm tau zoo dua. Qhov kev tsim no ua rau TOPCON cov vaj huam sib luag ua tiav cov zis hluav taws xob siab dua thiab cov coefficient kub zoo dua, ua rau lawv zoo tagnrho rau kev teeb tsa hauv huab cua kub lossis thaj chaw uas muaj kev hloov pauv kub loj.
Thaum piv peb lub thev naus laus zis no, nws yog ib qho tseem ceeb uas yuav tsum xav txog lawv cov txiaj ntsig thiab kev txwv. PERC panels paub txog lawv qhov kev ua haujlwm zoo thiab kev tsim hluav taws xob, ua rau lawv yog qhov kev xaiv txhim khu kev qha rau kev ua kom muaj zog ntau hauv ntau qhov chaw ib puag ncig. Heterojunction panels, ntawm qhov tod tes, ua tau zoo hauv cov xwm txheej tsis muaj teeb pom kev zoo thiab muaj kev tiv thaiv kub zoo dua, ua rau lawv haum rau thaj chaw uas muaj huab cua tsis paub tseeb. TOPCON panels sawv tawm rau lawv cov coefficient kub zoo heev thiab kev ua tau zoo tag nrho hauv huab cua kub, ua rau lawv yog thawj qhov kev xaiv rau kev teeb tsa hauv thaj chaw hnub ci thiab sov.
Tag nrho hauv txhua qhov, kev lag luam hnub ci txuas ntxiv mus loj hlob nrog kev qhia txog cov thev naus laus zis siab heev xws li PERC, HJT thiab TOPCON lub hnub ci vaj huam sib luag. Txhua yam ntawm cov thev naus laus zis no muaj cov yam ntxwv tshwj xeeb thiab cov txiaj ntsig uas tuaj yeem ua tau raws li cov xwm txheej ib puag ncig thiab kev xav tau lub zog. Los ntawm kev nkag siab txog qhov sib txawv ntawm cov thev naus laus zis no, cov neeg siv khoom thiab cov lag luam tuaj yeem txiav txim siab tau zoo thaum xaiv cov thev naus laus zis hnub ci vaj huam sib luag uas zoo tshaj plaws rau lawv cov kev xav tau tshwj xeeb. Raws li qhov kev thov rau lub zog rov ua dua tshiab txuas ntxiv mus, cov thev naus laus zis hnub ci vaj huam sib luag tshiab no yuav ua lub luag haujlwm tseem ceeb hauv kev tsav tsheb hloov mus rau qhov chaw muaj zog ruaj khov thiab zoo rau ib puag ncig.
