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.
