Ua hoʻomohala ʻo French solar energy institute INES i nā modula PV hou me nā thermoplastics a me nā fiber maoli i hoʻokumu ʻia ma ʻEulopa, e like me ka flax a me ka basalt.Manaʻo ka poʻe ʻepekema e hōʻemi i ka wāwae kaiapuni a me ke kaumaha o nā panela solar, ʻoiai e hoʻomaikaʻi ana i ka hana hou ʻana.
ʻO kahi pā aniani i hana hou ʻia ma ke alo a me kahi huila olonā ma hope

Ke hoʻomohala nei nā mea noiʻi ma France's National Solar Energy Institute (INES) - he mahele o ka French Alternative Energies and Atomic Energy Commission (CEA) - i nā modules solar e hōʻike ana i nā mea bio-based hou ma mua a ma hope.
"ʻOiai ua lilo ka wāwae kalapona a me ka nānā ʻana i ka pōʻai ola i kēia manawa i nā kumu koʻikoʻi i ke koho ʻana i nā paneli photovoltaic, e lilo ka ʻimi ʻana i nā mea waiwai i mea koʻikoʻi ma ʻEulopa i nā makahiki e hiki mai ana," wahi a Anis Fouini, ka luna o CEA-INES. , ma kahi ninaninau me ka pv magazine France.
'Ōleloʻo Aude Derrier, ka mea hoʻoponopono o ka papahana noiʻi, ua nānā kona mau hoa hana i nā mea likeʻole i kēia manawa, eʻike i kahi mea e hiki ai i nā mea hana module ke hana i nā paneli e hoʻonui ai i ka hana, ka lōʻihi, a me ke kumukūʻai, me ka hoʻohaʻahaʻaʻana i ka hopena o ke kaiapuni.ʻO ka mea hōʻike mua he heterojunction (HTJ) solar cell i hoʻohui ʻia i loko o kahi mea hoʻohui āpau.
"ʻO kaʻaoʻao mua i hanaʻia me kahi polymer i hoʻopihaʻia i ka fiberglass, e hāʻawi ana i ka māmā," i'ōlelo aiʻo Derrier."ʻO ka ʻaoʻao hope i hana ʻia me ka composite e pili ana i nā thermoplastics kahi i ulana ʻia ai nā fibers ʻelua, flax a me basalt, e hāʻawi ai i ka ikaika mechanical, akā ʻoi aku ka maikaʻi o ke kūʻē ʻana i ka haʻahaʻa."
Hoʻokumu ʻia ka flax mai ka ʻākau o Farani, kahi i loaʻa ai ka ʻoihana kaiaola holoʻokoʻa.Loaʻa ka basalt ma nā wahi ʻē aʻe o ʻEulopa a ua ulana ʻia e kekahi hoa hana ʻoihana o INES.Ua hōʻemi kēia i ka footprint carbon e 75 grams o CO2 per watt, i hoʻohālikelike ʻia me kahi module kuhikuhi o ka mana like.Ua ʻoi aku ka maikaʻi o ke kaumaha a ʻoi aku ka liʻiliʻi ma mua o 5 kilokani no ka mika square.
"Ke kuhikuhi nei kēia module i ka PV rooftop a me ka hoʻohui ʻana o ka hale," wahi a Derrier.“ʻO ka pōmaikaʻi ʻo ia ka ʻeleʻele maoli i ka waihoʻoluʻu, ʻaʻohe pono o ka pepa kua.Ma ke ʻano o ka hana hou ʻana, mahalo i nā thermoplastics, hiki ke hoʻoheheʻe ʻia, ʻoi aku ka maʻalahi o ka hoʻokaʻawale ʻana o nā papa.
Hiki ke hana i ka module me ka hoʻololi ʻole i nā kaʻina hana o kēia manawa.Ua ʻōlelo ʻo Derrier ʻo ka manaʻo e hoʻoili i ka ʻenehana i nā mea hana, me ka ʻole o ka hoʻopukapuka hou.
"ʻO ka mea nui wale nō ka loaʻa ʻana o nā freezers e mālama i nā mea a ʻaʻole e hoʻomaka i ke kaʻina hana cross-linking resin, akā ʻo ka hapa nui o nā mea hana i kēia lā ke hoʻohana nei i ka prepreg a ua lako ʻia no kēia," wahi āna.
"Ua hana mākou i ka lua o ke ola o ke aniani a hoʻomohala i kahi module i hoʻohana hou ʻia i ke aniani 2.8 mm i hoʻohana hou ʻia mai kahi module kahiko," wahi a Derrier."Ua hoʻohana pū mākou i kahi encapsulant thermoplastic ʻaʻole pono i ka hoʻopili ʻana, no laila e maʻalahi ke hana hou ʻana, a me ka thermoplastic composite me ka flax fiber no ke kū'ē."
ʻO ka ʻaoʻao hope ʻole basalt-free o ka module he kala olonā maoli, hiki ke hoihoi maikaʻi ʻia no nā mea kākau e pili ana i ka hoʻohui ʻana o ka facade, no ka laʻana.Eia kekahi, ua hōʻike ka hāmeʻa helu INES i ka hōʻemi ʻana o 10% i ka footprint carbon.
"He mea nui ia e nīnau i nā kaulahao lako photovoltaic," wahi a Jouini."Me ke kōkua o ka ʻāina ʻo Rhône-Alpes i loko o ka hoʻolālā o ka International Development Plan, no laila ua hele mākou e ʻimi i nā mea pāʻani ma waho o ka lālā lā e ʻimi i nā thermoplastics hou a me nā fibers hou.Ua noʻonoʻo nō hoʻi mākou e pili ana i ke kaʻina hana lamination o kēia manawa, he ikaika loa ka ikehu. "
Ma waena o ka pressurization, ka paʻi ʻana a me ka manawa hoʻoluʻu, ʻo ka lamination ka mea maʻamau ma waena o 30 a 35 mau minuke, me kahi mahana hana ma kahi o 150 C a 160 C.
"Akā, no nā modula e hoʻohui nui ana i nā mea eco-designed, pono ia e hoʻololi i nā thermoplastics ma kahi o 200 C a 250 C, me ka ʻike ʻana he maʻalahi ka ʻenehana HTJ i ka wela a ʻaʻole pono ma mua o 200 C," wahi a Derrier.
Ke hui pū nei ke keʻena noiʻi me ka loea induction thermocompression i hoʻokumu ʻia ma Farani, ʻo Roctool, e hōʻemi i nā manawa pōʻai a hana i nā ʻano e like me ka makemake o nā mea kūʻai.Hoʻohui pū lākou i kahi module me kahi alo hope i hana ʻia me ka polypropylene-type thermoplastic composite, kahi i hoʻohui ʻia ai nā fiber carbon recycled.Hana ʻia ka ʻaoʻao mua me nā thermoplastics a me ka fiberglass.
"ʻO ke kaʻina hana thermocompression induction o Roctool e hiki ai ke wela i nā papa ʻelua i mua a me hope me ka wikiwiki, me ka ʻole o ka hiki ʻana i 200 C ma ke kumu o nā pūnaewele HTJ," wahi a Derrier.
Ua ʻōlelo ka ʻoihana he haʻahaʻa ka hoʻopukapuka kālā a hiki i ke kaʻina hana ke hoʻokō i kahi manawa pōkole o nā minuke wale nō, ʻoiai e hoʻohana ana i ka ikehu liʻiliʻi.Kuhi ʻia ka ʻenehana i nā mea hana composite, e hāʻawi iā lākou i ka hiki ke hana i nā ʻāpana o nā ʻano like ʻole a me nā nui, ʻoiai e hoʻohui pū ana i nā mea māmā a ʻoi aku ka lōʻihi.
