Tau qhov twg los: fraunhofer
Ua ke nrog lawv cov phiaj xwm kev sib koom tes, cov kws tshawb fawb ntawm Photovoltaic Technology Kev Ntsuam Xyuas Chaw PV-TEC ntawm Fraunhofer lub koom haum rau Hnub Ci Lub Zog Hluav Taws Xob ISE hauv Freiburg tau ua tiav kev txhim kho cov tsoos tshuaj ntsuam luam ntawv txheej txheem rau cov kab zoo ntawm silicon solar cells. Siv cov ntxaij vab tshaus tshwj xeeb uas tau tsim, cov phiaj xwm pab pawg muaj peev xwm tsim cov ntiv tes sib tiv tauj nrog qhov dav ntawm tsuas yog 19 µm thiab qhov siab ntawm 18 µm hauv ib kauj ruam luam ntawv. Qhov no txhais tau tias yuav tsum tau nce txog li 30 feem pua cov nyiaj tsawg dua, uas ua rau muaj kev txo qis hauv cov nqi tsim khoom.
Silicon solar cells vam khom cov hluav taws xob hlau ntawm lawv sab pem hauv ntej thiab tom qab kom nqa hluav taws xob tsim hluav taws xob hauv cov khoom siv hluav taws xob semiconductor los ntawm lub teeb tsis muaj teeb meem. Txog qhov kawg no, lub vijtsam flatbed luam ntawv txheej txheem feem ntau yog siv los luam tawm cov xov tooj sib txuas zoo mus rau sab xub ntiag ntawm lub xov tooj. Cov kab sib chaws no yuav tsum thaiv kom tsawg li sai tau ntawm lub xov tooj ntawm tes nquag los ntawm kev sib raug zoo rau lub teeb thiab yuav tsum muaj kev coj zoo txaus kom ua rau lub hnub ci hlwb 'series tsis tshua muaj. Cov kev sib tw thev naus laus zis hauv kev tshuaj ntsuam luam ntawv cov lus dag hauv kev tsim cov nqaim sib txuas tau txuas ntxiv cov ntiv tes nrog qhov siab kom txaus rau kev zoo tom qab. Kev luam tawm ntiv tes tiv thaiv zoo kawg nkaus yuav tsum tau siv cov kws tshaj lij tshwj xeeb cov ntxaij vab tshaus tshwj xeeb thiab cov duab kos rau xim hlau ntxiv rau kom tiav qhov ua tiav ntawm cov vijtsam luam ntawv nws yog xim hlau.
" Ua haujlwm ua ke nrog cov koom tes ua lag luam nyob hauv kev lag luam zoo rau kev tshuaj ntsuam luam ntawv metallization, tshwj xeeb nrog cov tshuaj ntsuam lub tuam txhab Koenen GmbH thiab Murakami Co. Ltd. nrog rau tshuaj ntsuam tshuaj muag Kissel + Wolf GmbH, peb tau tswj kom txo qhov sib chwv cov ntiv tes kom tsawg dua dua li 20 micrometers - qhov kev txo qis ntawm 30 txog 40 feem pua piv nrog cov qauv kev lag luam tam sim no, ”piav qhia Dr.-Ing. Andreas Lorenz, tus thawj tswj phiaj xwm hauv pab pawg "Printing Technology" ntawm Fraunhofer ISE. Kev tsim kho cov ntxaij vab tshaus zoo tau siv rau hauv qhov metallization ntawm passivated emitter thiab sab nram qab kev sib cuag (PERC) hnub ci hlwb hauv ob qhov kev xeem ywj pheej. Siv xws li qhov screen ua rau nws muaj peev xwm tsim cov ntiv tes sib chwv nrog qhov dav ntawm tsuas yog 19 µm thiab qhov siab txog 18 inm hauv ib kauj ruam luam ntawv nkaus xwb. Tsis tsuas yog cov ntiv tes sib tiv tauj nqaim heev, lawv cov khoom siv hluav taws xob kuj ua tau zoo heev. Thaum muab tso ua ke rau hauv cov qauv - tshwj xeeb tshaj yog cov thev naus laus zis tshiab xws li kev sib txuam ntau ntawm cov npav sib xyaw nrog 8 txog 15 busbars - lawv muaj peev xwm txo qis ntawm lub zog poob hauv cov ntiv tes sib cuag. Cov txheej txheem luam tawm tshiab tsim tawm no yuav tsum txog 30 feem pua nyiaj tsawg dua piv nrog cov qauv kev lag luam tam sim no nrog cov ntiv tes sib tiv tauj dav dav kwv yees li 30 µm.
Raws li ib feem ntawm kev sim, PERC hnub ci hlwb tau metallized siv kev pom qhov ntsuas tsis zoo; ib qho me ntsis ntiv tes qhov dav ntawm 24 µm tau raug xaiv vim muaj qhov txwv nrog kev txiav txim siab muaj cov naj npawb ntawm busbars ntawm lub hnub ci cell (hauv qhov no 5). Qhov zoo tshaj plaws PERC hnub ci cell hauv qhov kev ntsuas no tau ua tiav kev ua tiav ntawm h = 22.1%.
" Kev siv lub tshuab ua haujlwm tsim kev lag luam uas tsim tau zoo heev thiab kev siv tshuab ua kom zoo rau cov kab hlau zoo, nws yuav pib tsim cov khoom nruab hnub ci nrog cov ntiv tes sib ze uas pom tsis tau ntawm qhov kev lag luam yav tom ntej. Qhov no yuav ua rau muaj txiaj ntsig zoo rau cov ntawv thov nyob rau hauv photovoltaics sib xyaw, qhov zoo nkauj, homogeneous qhov chaw muaj peev xwm xav tau, "hais tias Dr. Florian Clement, Lub Taub Hau ntawm Kev Tsim Kho Tshuab - Chav Haujlwm thiab Metallization Department ntawm Fraunhofer ISE.
Cov txiaj ntsig ntawm cov kev xeem no yuav nthuav tawm ntawm ob lub rooj sib tham PV tom ntej no - lub tebchaws 36 PVSEC hauv Marseille, Fab Kis, thiab 29th PVSEC hauv Xi'an, Suav.
Cov haujlwm sib koom tes "FINALE", uas ua rau kev txhim kho cov kab ntawv tshuaj ntsuam luam ntawv zoo nkauj thiab cov kws tshawb nrhiav tau tiav qee qhov kev tshwm sim no, tau nyiaj los ntawm German Tsoomfwv Saib Xyuas Nyiaj Txiag thiab Lub Zog BMWi thiab tau ua haujlwm nrog kev koom tes nrog kev lag luam koom tes Koenen GmbH , Kissel + Hma GmbH thiab Wickon Hightech GmbH.
Ntxiv mus zoo-kab tshuaj ntsuam cov ntawv luam tawm uas tau nthuav tawm ntawm no tau pom nyob hauv kev koom tes ntawm Murakami Co. Ltd. thiab Fraunhofer ISE.
