Fabkis hnub ci zog lub koom haum INES tau tsim PV modules tshiab nrog cov thermoplastics thiab ntuj fibers los ntawm cov teb chaws Europe, xws li flax thiab basalt. Cov kws tshawb fawb tsom kom txo qis ib puag ncig hneev taw thiab qhov hnyav ntawm lub hnub ci vaj huam sib luag, thaum txhim kho kev rov ua dua tshiab.

Cov kws tshawb fawb ntawm Fabkis lub National Solar Energy Institute (INES) - ib qho kev faib ntawm Fab Kis Kev Xaiv Hluav Taws Xob thiab Atomic Energy Commission (CEA) - tab tom tsim lub hnub ci modules uas muaj cov khoom siv bio-based tshiab nyob rau sab pem hauv ntej thiab nram qab.
Anis Fouini, tus thawj coj ntawm CEA-INES tau hais tias "Raws li cov pa roj carbon hneev taw thiab kev ntsuas lub neej tam sim no tau dhau los ua cov txheej txheem tseem ceeb hauv kev xaiv cov khoom siv hluav taws xob photovoltaic, cov khoom siv yuav dhau los ua ib qho tseem ceeb hauv Tebchaws Europe nyob rau ob peb xyoos tom ntej no," said Anis Fouini, tus thawj coj ntawm CEA-INES. , hauv kev xam phaj nrog pv magazine France.
Aude Derrier, tus kws tshawb fawb txog qhov project, hais tias nws cov npoj yaig tau saib ntau yam ntaub ntawv uas twb muaj lawm, nrhiav ib qho uas tuaj yeem tso cai rau cov tuam txhab tsim qauv tsim cov vaj huam sib luag uas txhim kho kev ua tau zoo, kav ntev, thiab tus nqi, thaum txo kev cuam tshuam ib puag ncig. Thawj tus qauv qhia muaj heterojunction (HTJ) hnub ci hlwb ua ke rau hauv cov khoom siv sib xyaw ua ke.
"Lub sab pem hauv ntej yog ua los ntawm fiberglass-filled polymer, uas muab kev pom tseeb," Derrier hais. "Lub sab nraub qaum yog ua los ntawm kev sib xyaw ua ke raws li cov khoom siv thermoplastics uas muaj kev sib txuas ntawm ob fibers, flax thiab basalt, uas yuav muab cov neeg kho tshuab lub zog, tab sis kuj zoo dua rau cov av noo."
Cov flax yog los ntawm sab qaum teb Fabkis, qhov twg tag nrho cov kev lag luam ecosystem twb muaj lawm. Cov basalt yog los ntawm lwm qhov hauv Tebchaws Europe thiab yog woven los ntawm kev lag luam koom tes ntawm INES. Qhov no txo cov pa roj carbon hneev taw los ntawm 75 grams ntawm CO2 ib watt, piv rau cov qauv siv ntawm tib lub zog. Qhov hnyav kuj tau kho kom zoo thiab tsawg dua 5 kilograms ib square meter.
"Cov qauv no yog tsom rau lub ru tsev PV thiab kev koom ua ke hauv tsev," said Derrier. "Qhov zoo dua yog tias nws yog xim dub hauv cov xim, tsis tas yuav tsum muaj daim ntawv rov qab. Nyob rau hauv cov nqe lus ntawm recycling, ua tsaug rau cov thermoplastics, uas yuav remelted, kev sib cais ntawm txheej kuj technically yooj yim. "
Lub module tuaj yeem ua tsis tau hloov cov txheej txheem tam sim no. Derrier tau hais tias lub tswv yim yog hloov cov thev naus laus zis mus rau cov tuam txhab tsim khoom, tsis tas yuav nqis peev ntxiv.
"Ib qho tseem ceeb tshaj plaws yog kom muaj lub freezers khaws cov khoom thiab tsis txhob pib cov txheej txheem sib txuas, tab sis feem ntau cov tuam txhab niaj hnub no siv prepreg thiab twb tau nruab rau qhov no," nws hais.
"Peb tau ua haujlwm ntawm lub neej thib ob ntawm iav thiab tsim cov qauv tsim los ntawm rov siv dua 2.8 hli iav uas los ntawm cov qauv qub," said Derrier. "Peb kuj tau siv cov thermoplastic encapsulant uas tsis tas yuav muaj kev sib txuas, uas yuav yooj yim rau rov siv dua, thiab cov thermoplastic composite nrog flax fiber rau kev tiv thaiv."
Lub ntsej muag tsis muaj basalt tom qab ntawm lub module muaj cov xim linen, uas tuaj yeem ua kom zoo nkauj rau cov kws tsim vaj tsev nyob rau hauv cov nqe lus ntawm facade kev koom ua ke, piv txwv li. Tsis tas li ntawd, INES cov cuab yeej suav tau pom qhov txo qis ntawm 10% ntawm cov pa roj carbon hneev taw.
Jouini tau hais tias "Tam sim no nws yog qhov yuav tsum tau nug txog cov khoom siv hluav taws xob photovoltaic," said Jouini. "Nrog kev pab los ntawm Rhône-Alpes cheeb tsam nyob rau hauv lub moj khaum ntawm International Development Plan, peb thiaj li mus nrhiav players sab nraum lub hnub ci sector mus nrhiav tshiab thermoplastics thiab fibers tshiab. Peb kuj tau xav txog cov txheej txheem lamination tam sim no, uas yog lub zog siv zog heev. "
Nyob nruab nrab ntawm lub siab, lub nias thiab lub caij txias, lub lamination feem ntau kav li ntawm 30 mus rau 35 feeb, nrog rau kev khiav hauj lwm kub ntawm ib ncig ntawm 150 C rau 160 C.
"Tab sis rau cov qauv uas nce ntxiv cov khoom siv hauv eco-tsim, nws yog ib qho tsim nyog los hloov cov thermoplastics ntawm ib ncig ntawm 200 C rau 250 ° C, paub tias HTJ thev naus laus zis yog rhiab rau cua sov thiab yuav tsum tsis pub tshaj 200 C," said Derrier.
Lub koom haum tshawb fawb tau koom tes nrog Fabkis-based induction thermocompression tus kws tshaj lij Roctool, txhawm rau txo lub sijhawm voj voog thiab ua cov duab raws li qhov xav tau ntawm cov neeg siv khoom. Ua ke, lawv tau tsim ib qho module nrog lub ntsej muag tom qab ua los ntawm polypropylene-hom thermoplastic composite, uas siv cov pa roj carbon fiber ntau tau ua ke. Sab pem hauv ntej yog ua los ntawm thermoplastics thiab fiberglass.
"Roctool's induction thermocompression txheej txheem ua rau nws muaj peev xwm ua kom sov ob sab pem hauv ntej thiab nram qab daim hlau sai, tsis tas yuav ncav cuag 200 C ntawm lub hauv paus ntawm HTJ hlwb," Derrier hais.
Lub tuam txhab thov cov peev nyiaj qis dua thiab cov txheej txheem tuaj yeem ua tiav lub sijhawm voj voog ntawm ob peb feeb, thaum siv lub zog tsawg dua. Cov thev naus laus zis yog tsom rau cov tuam txhab tsim khoom sib xyaw, kom muab lawv qhov ua tau zoo ntawm cov duab sib txawv thiab qhov ntau thiab tsawg, thaum sib xyaw cov khoom sib dua thiab ruaj khov dua.
