Fraunhofer ISE nyob rau hauv lub teb chaws Yelemees tab tom siv nws cov FlexTrail tshuab luam ntawv rau kev ncaj qha metallization ntawm silicon heterojunction hnub ci hlwb.Nws hais tias kev siv tshuab txo qis kev siv nyiaj thaum tswj kev ua haujlwm siab.
Cov kws tshawb fawb ntawm Fraunhofer Institute for Solar Energy Systems (ISE) hauv lub teb chaws Yelemees tau tsim cov txheej txheem hu ua FlexTrail Printing, ib txoj hauv kev los luam cov silicon heterojunction (SHJ) nyiaj nanoparticle solar cells yam tsis muaj busbar.Pem hauv ntej electrode plating txoj kev.
"Tam sim no peb tab tom tsim lub tshuab luam ntawv FlexTrail sib npaug uas tuaj yeem ua cov hnub ci ua haujlwm tau zoo sai, ntseeg tau thiab raug," tus kws tshawb fawb Jörg Schube hais rau pv."Vim tias cov dej haus tsawg heev, peb cia siab tias cov tshuaj photovoltaic yuav muaj kev cuam tshuam zoo rau tus nqi thiab kev cuam tshuam ib puag ncig."
FlexTrail luam ntawv tso cai rau kev siv cov ntaub ntawv ntawm cov viscosities sib txawv nrog cov qauv yam tsawg kawg nkaus qhov dav.
Cov kws tshawb fawb tau hais tias "Nws tau pom tias muab kev siv nyiaj zoo, kev sib cuag sib cuag, thiab siv nyiaj tsawg," cov kws tshawb fawb tau hais."Nws tseem muaj peev xwm txo qis lub sijhawm voj voog ntawm ib lub xov tooj ntawm tes vim nws qhov yooj yim thiab cov txheej txheem kev ruaj ntseg, thiab yog li nws tau npaj rau yav tom ntej hloov tsheb los ntawm lub chaw soj nstuam mus rau lub Hoobkas.
Txoj kev no suav nrog kev siv cov iav hloov tau yooj yim heev uas muaj cov kua dej ntawm atmospheric siab txog li 11 bar.Thaum lub sij hawm luam ntawv, lub capillary yog nyob rau hauv kev sib cuag nrog lub substrate thiab txav tsis tu ncua raws nws.
"Qhov yooj yim thiab yooj yim ntawm cov iav capillaries tso cai rau kev ua haujlwm tsis muaj kev puas tsuaj," cov kws tshawb fawb tau hais tias, qhov no tseem tso cai rau cov qauv nkhaus los luam tawm."Tsis tas li ntawd, nws ntsuas qhov ua tau waviness ntawm lub hauv paus."
Pab neeg tshawb fawb tau tsim ib lub xov tooj ntawm tes roj teeb modules siv SmartWire Connection Technology (SWCT), ntau lub xov tooj sib txuas siv tshuab raws li qhov kub thiab txias ntawm cov xov tooj tooj liab.
"Feem ntau, cov xov hlau tau muab tso rau hauv cov ntawv ci polymer thiab txuas nrog lub hnub ci hlwb siv cov hlau tsis siv neeg kos duab.Cov pob qij txha tau tsim nyob rau hauv cov txheej txheem lamination tom ntej ntawm cov txheej txheem kub sib xws nrog silicon heterojunctions, "cov kws tshawb fawb hais.
Siv ib leeg capillary, lawv tsis tu ncua luam lawv cov ntiv tes, ua rau cov nyiaj-raws li cov kab ua haujlwm nrog qhov loj me ntawm 9 µm.Tom qab ntawd lawv tsim SHJ hnub ci hlwb nrog kev ua haujlwm ntawm 22.8% ntawm M2 wafers thiab siv cov hlwb no los ua 200mm x 200mm ib leeg cell modules.
Lub vaj huam sib luag ua tiav lub zog hloov pauv ntawm 19.67%, qhib qhov hluav taws xob hluav taws xob ntawm 731.5 mV, luv luv tam sim no ntawm 8.83 A, thiab lub luag haujlwm voj voog ntawm 74.4%.Nyob rau hauv sib piv, qhov screen-luam ntawv siv module muaj ib tug efficiency ntawm 20.78%, qhib Circuit Court voltage ntawm 733.5 mV, luv luv Circuit Court tam sim no ntawm 8.91 A, thiab lub luag hauj lwm voj voog ntawm 77.7%.
"FlexTrail muaj qhov zoo ntawm cov tshuab luam ntawv inkjet nyob rau hauv cov nqe lus ntawm kev hloov dua siab tshiab.Tsis tas li ntawd, nws muaj qhov zoo ntawm kev ua kom yooj yim dua thiab yog li kev lag luam yooj yim dua, vim txhua tus ntiv tes tsuas yog yuav tsum tau luam tawm ib zaug, thiab ntxiv rau, kev siv nyiaj tsawg dua.qis dua, cov kws tshawb fawb tau hais tias, qhov nyiaj poob qis yog kwv yees li ntawm 68 feem pua.
Lawv tau nthuav tawm lawv cov txiaj ntsig hauv daim ntawv "Direct FlexTrail Plating nrog Kev Siv Nyiaj Tsawg rau Heterojunction Silicon Solar Cells: Kev Ntsuas Kev Ua Haujlwm ntawm Hnub Ci Cell thiab Modules" tsis ntev los no tau tshaj tawm hauv phau ntawv xov xwm Energy Technology.
"Yuav kom ua txoj hauv kev rau kev lag luam kev lag luam ntawm FlexTrail luam ntawv, tam sim no lub taub hau luam ntawv sib npaug tau tsim," tus kws tshawb fawb xaus lus."Nyob rau yav tom ntej, nws tau npaj yuav siv nws tsis yog rau SHD metallization, tab sis kuj rau tandem solar cells, xws li perovskite-silicon tandem."
