Masu bincike a Cibiyar Makamashin Solar Solar ta Faransa (INES) - wani yanki na Madadin Makamashi na Faransa da Hukumar Makamashin Atomic (CEA) - suna haɓaka samfuran hasken rana waɗanda ke nuna sabbin kayan tushen halittu a gaba da na baya.
Anis Fouini, darektan CEA-INES ya ce "Kamar yadda sawun carbon da kuma nazarin yanayin rayuwa yanzu ya zama mahimman ma'auni a cikin zaɓin bangarorin photovoltaic, samar da kayan aiki zai zama muhimmin abu a Turai a cikin 'yan shekaru masu zuwa." , a wata hira da mujallar pv Faransa.
Aude Derrier, mai kula da aikin binciken, ta ce abokan aikinta sun duba abubuwa daban-daban da suka wanzu, don nemo wanda zai ba da damar masana'antun kera kayan aikin su samar da bangarori masu inganta aiki, karko, da tsada, tare da rage tasirin muhalli. Mai nuni na farko ya ƙunshi ƙwayoyin hasken rana heterojunction (HTJ) hadedde cikin wani abu mai haɗe-haɗe.
"A gefe na gaba an yi shi da fiberglass-cikakken polymer, wanda ke ba da gaskiya," in ji Derier. "Bayanan baya an yi shi ne da wani abu wanda ya dogara da thermoplastics wanda aka haɗa saƙa na zaruruwa biyu, flax da basalt, wanda zai ba da ƙarfin injin, amma kuma mafi kyawun juriya ga zafi."
An samo flax ne daga arewacin Faransa, inda dukkanin yanayin masana'antu ya riga ya kasance. Basalt an samo shi a wani wuri a Turai kuma abokin masana'antu na INES ne ke saka shi. Wannan ya rage sawun carbon da gram 75 na CO2 kowace watt, idan aka kwatanta da tsarin tunani na wannan iko. An kuma inganta nauyin nauyin kuma bai wuce kilogiram 5 a kowace murabba'in mita ba.
"Wannan samfurin yana nufin PV na rufin rufin da haɗin ginin," in ji Derier. “Amfanin shi ne, a zahiri baƙar fata ne a launi, ba tare da buƙatar takardar baya ba. Dangane da sake yin amfani da su, godiya ga thermoplastics, wanda za'a iya sake narkewa, rabuwar yadudduka kuma ya fi sauƙi a fasaha."
Za'a iya yin tsarin ba tare da daidaita ayyukan yanzu ba. Derier ya ce ra'ayin shine don canja wurin fasaha zuwa masana'antun, ba tare da ƙarin zuba jari ba.
"Mahimmanci kawai shine a sami injin daskarewa don adana kayan kuma kada a fara tsarin haɗin gwiwar resin, amma yawancin masana'antun a yau suna amfani da prepreg kuma an riga an shirya su don wannan," in ji ta.
"Mun yi aiki a kan rayuwa ta biyu na gilashi kuma mun samar da wani tsari wanda ya ƙunshi gilashin 2.8 mm da aka sake amfani da shi wanda ya fito daga wani tsohon tsarin," in ji Derier. "Mun kuma yi amfani da wani thermoplastic encapsulant wanda baya buƙatar haɗin kai, wanda saboda haka zai zama mai sauƙi don sake yin amfani da shi, da kuma kayan aikin thermoplastic tare da fiber flax don juriya."
Fuskar baya na basalt-free na module yana da launi na lilin na halitta, wanda zai iya zama mai ban sha'awa ga masu gine-gine dangane da haɗin facade, alal misali. Bugu da ƙari, kayan aikin lissafin INES ya nuna raguwar 10% a cikin sawun carbon.
"Yanzu ya zama wajibi a yi tambaya game da sarkar samar da wutar lantarki," in ji Jouini. "Tare da taimakon yankin Rhône-Alpes a cikin tsarin Tsarin Ci Gaban Kasa da Kasa, saboda haka mun je neman 'yan wasa a waje da sashin hasken rana don nemo sabbin thermoplastics da sabbin zaruruwa. Mun kuma yi tunani game da tsarin lamination na yanzu, wanda ke da ƙarfin kuzari sosai. "
Tsakanin matsin lamba, latsawa da lokacin sanyaya, lamination yawanci yana ɗaukar mintuna 30 zuwa 35, tare da zafin aiki na kusan 150 C zuwa 160 C.
"Amma ga nau'ikan da ke ƙara haɗa kayan da aka tsara na eco, ya zama dole a canza thermoplastics a kusa da 200 C zuwa 250 C, sanin cewa fasahar HTJ tana kula da zafi kuma dole ne ya wuce 200 C," in ji Derier.
Cibiyar binciken tana haɗin gwiwa tare da ƙwararren ƙwararren thermocompression na tushen Faransa Roctool, don rage lokutan sake zagayowar da yin siffofi daidai da bukatun abokan ciniki. Tare, sun ƙirƙira wani tsari mai fuska na baya wanda aka yi da nau'in thermoplastic irin na polypropylene, wanda aka haɗa filayen carbon da aka sake yin fa'ida. An yi gefen gaba da thermoplastics da fiberglass.
"Tsarin shigar da thermocompression na Roctool yana ba da damar zazzage faranti biyu na gaba da na baya da sauri, ba tare da kai 200 C a tsakiyar sel HTJ ba," in ji Derier.
