Bungwe la ku France la mphamvu ya dzuwa la INES lapanga ma module atsopano a PV okhala ndi thermoplastics ndi ulusi wachilengedwe wopangidwa ku Europe, monga fulakisi ndi basalt. Asayansiwa akufuna kuchepetsa kuchuluka kwa chilengedwe komanso kulemera kwa mapanelo adzuwa, kwinaku akukonza zobwezeretsanso.
A zobwezerezedwanso galasi gulu kutsogolo ndi bafuta gulu kumbuyo

Ofufuza ku France's National Solar Energy Institute (INES) - gawo la French Alternative Energies and Atomic Energy Commission (CEA) - akupanga ma module a solar okhala ndi zida zatsopano zakutsogolo ndi kumbuyo.
"Monga momwe mpweya wa carbon footprint ndi kusanthula kwa moyo wanu tsopano zakhala zofunikira pakusankha mapanelo a photovoltaic, kufufuza kwa zipangizo kudzakhala chinthu chofunika kwambiri ku Ulaya m'zaka zingapo zikubwerazi," adatero Anis Fouini, mkulu wa CEA-INES. , pokambirana ndi pv magazine France.
Aude Derrier, wotsogolera polojekitiyi, adanena kuti anzake ayang'ana zinthu zosiyanasiyana zomwe zilipo kale, kuti apeze imodzi yomwe ingalole opanga ma module kuti apange mapanelo omwe amawongolera ntchito, kulimba, ndi mtengo, ndikuchepetsa kuwonongeka kwa chilengedwe. Chiwonetsero choyamba chimakhala ndi maselo a dzuwa a heterojunction (HTJ) ophatikizidwa muzinthu zonse.
"Kumbali yakutsogolo kumapangidwa ndi polymer yodzaza ndi fiberglass, yomwe imapereka kuwonekera," adatero Derrier. "Kumbuyo kwake kumapangidwa ndi makina opangidwa ndi thermoplastics momwe kuluka kwa ulusi awiri, fulakesi ndi basalt, zaphatikizidwa, zomwe zimapereka mphamvu zamakina, komanso kukana bwino ku chinyezi."
Fulakisi imachokera kumpoto kwa France, kumene chilengedwe chonse cha mafakitale chilipo kale. Basaltyi imatengedwa kwina ku Ulaya ndipo amalukidwa ndi mnzake wamakampani a INES. Izi zinachepetsa mpweya wa carbon ndi 75 magalamu a CO2 pa watt, poyerekeza ndi gawo lofotokozera la mphamvu yomweyo. Kulemerako kudakonzedwanso ndipo ndi kochepera ma kilogalamu 5 pa lalikulu mita.
"Module iyi imayang'ana padenga la PV ndi kuphatikiza kwanyumba," adatero Derrier. "Ubwino wake ndi wakuti mwachibadwa ndi wakuda, popanda kufunikira kwa backsheet. Pankhani yobwezeretsanso, chifukwa cha thermoplastics, yomwe imatha kusinthidwa, kulekanitsa zigawozo kumakhala kosavuta mwaukadaulo. ”
Module ikhoza kupangidwa popanda kusintha njira zamakono. Derrier adati lingaliro ndikusamutsa ukadaulo kwa opanga, popanda ndalama zowonjezera.
"Chofunika chokha ndicho kukhala ndi mafiriji osungira zinthuzo osati kuyambitsa njira yolumikizira utomoni, koma opanga ambiri masiku ano amagwiritsa ntchito prepreg ndipo ali ndi zida za izi," adatero.
"Tinagwira ntchito pa moyo wachiwiri wa galasi ndipo tinapanga gawo lopangidwanso ndi galasi la 2.8 mm lomwe limachokera ku module yakale," adatero Derrier. "Tagwiritsanso ntchito thermoplastic encapsulant yomwe simafunikira kulumikizana, komwe kudzakhala kosavuta kukonzanso, komanso kompositi ya thermoplastic yokhala ndi ulusi wa fulakesi kuti ikanize."
Kumbuyo kwa basalt kumbuyo kwa gawoli kuli ndi utoto wansalu wachilengedwe, womwe ungakhale wosangalatsa kwa omanga molingana ndi kuphatikiza kwa facade, mwachitsanzo. Kuphatikiza apo, chida chowerengera cha INES chinawonetsa kuchepetsedwa kwa 10% pamayendedwe a carbon.
"Ndikofunikira tsopano kukayikira maunyolo amtundu wa photovoltaic," adatero Jouini. "Mothandizidwa ndi dera la Rhône-Alpes mkati mwa International Development Plan, tinapita kukafunafuna osewera kunja kwa gawo la solar kuti tipeze ma thermoplastics atsopano ndi ulusi watsopano. Tidaganiziranso za momwe lamination liliri pano, lomwe ndi logwiritsa ntchito mphamvu zambiri. ”
Pakati pa kupanikizika, kukakamiza ndi kuzizira, kuyamwa nthawi zambiri kumakhala pakati pa 30 ndi 35 mphindi, ndi kutentha kwapakati pa 150 C mpaka 160 C.
"Koma kwa ma modules omwe amaphatikizanso zinthu zopangidwa ndi eco, m'pofunika kusintha thermoplastics pafupifupi 200 C mpaka 250 C, podziwa kuti teknoloji ya HTJ imakhudzidwa ndi kutentha ndipo sayenera kupitirira 200 C," adatero Derrier.
Bungwe lofufuzali likugwirizana ndi katswiri waku France waku France wa thermocompression Roctool, kuti achepetse nthawi yozungulira ndikupanga mawonekedwe molingana ndi zosowa za makasitomala. Pamodzi, apanga gawo lokhala ndi nkhope yakumbuyo yopangidwa ndi polypropylene-mtundu wa thermoplastic composite, pomwe ulusi wa kaboni wokonzedwanso waphatikizidwa. Mbali yakutsogolo idapangidwa ndi thermoplastics ndi fiberglass.
"Roctool induction thermocompression process imapangitsa kutentha mbale ziwiri zakutsogolo ndi zakumbuyo mwachangu, osafikira 200 C pachimake cha ma cell a HTJ," adatero Derrier.
Kampaniyo imati ndalamazo ndizochepa ndipo ndondomekoyi ikhoza kukwaniritsa nthawi yozungulira mphindi zochepa chabe, pogwiritsa ntchito mphamvu zochepa. Ukadaulo umapangidwa ndi opanga ma composite, kuti awapatse mwayi wopanga magawo amitundu yosiyanasiyana ndi kukula kwake, ndikuphatikiza zida zopepuka komanso zolimba.
