Ofufuza a ku Danish akuti kuchiza maselo a dzuwa omwe sali odzaza ndi vitamini C amapereka antioxidant ntchito yomwe imachepetsa njira zowonongeka zomwe zimachokera ku kutentha, kuwala, ndi mpweya. Selo lidapeza mphamvu yosinthira mphamvu ya 9.97%, voliyumu yotseguka ya 0.69 V, kachulukidwe kakang'ono ka 21.57 mA/cm2, ndi kudzaza 66%.
Gulu la ofufuza ochokera ku University of Southern Denmark (SDU) likufuna kufanana ndi kupita patsogolo komwe kukuchitika pakusinthira mphamvu zama cell solar cell (OPV) opangidwa ndinon-fullerene acceptor (NFA)zipangizo zokhazikika zokhazikika.
Gululo linasankha ascorbic acid, yemwe amadziwikanso kuti vitamini C, ndipo adagwiritsa ntchito ngati gawo la passivation pakati pa zinc oxide (ZnO) electron transport layer (ETL) ndi photoactive layer ya ma cell a NFA OPV opangidwa ndi inverted device layer stack and semiconducting polima (PBDB-T:IT-4F).
Asayansi anamanga selo ndi indium tin oxide (ITO) wosanjikiza, ZnO ETL, vitamini C wosanjikiza, PBDB-T: IT-4F absorber, molybdenum oxide (MoOx) chonyamulira wosanjikiza wosanjikiza, ndi siliva (Ag). ) kukhudzana kwachitsulo.
Gululo linapeza kuti ascorbic acid imapanga photostabilizing effect, inanena kuti antioxidant ntchito imachepetsa njira zowonongeka zomwe zimachokera ku mpweya, kuwala ndi kutentha. Mayesero, monga mayamwidwe a ultraviolet, mawonekedwe a impedance, magetsi odalira kuwala ndi miyeso yaposachedwa, adawonetsanso kuti vitamini C imachepetsa kujambulidwa kwa mamolekyu a NFA ndikupondereza kubwerezanso, adawona kafukufukuyu.
Kusanthula kwawo kunawonetsa kuti, pambuyo pa 96 h ya kuwonongeka kosalekeza kwa zithunzi pansi pa 1 Dzuwa, zida zophatikizidwa zomwe zili ndi vitamini C interlayer zidasunga 62% yamtengo wake woyambirira, pomwe zida zowunikira zimangosunga 36% yokha.
Zotsatirazo zinasonyezanso kuti kukhazikika kwabwino sikunabwere pamtengo wokwanira. Chipangizo champikisano chidapeza mphamvu yosinthira mphamvu ya 9.97%, voliyumu yotseguka ya 0.69 V, kachulukidwe kakafupi kafupipafupi ka 21.57 mA/cm2, ndi kudzaza kwa 66%. Zida zowonetsera zomwe zilibe vitamini C, zowonetsera 9.85 % mphamvu, magetsi otsegula a 0.68V, afupipafupi a 21.02 mA/cm2, ndi 68%.
Atafunsidwa za kuthekera kwa malonda ndi scalability, Vida Engmann yemwe amatsogolera gulu paCenter for Advanced Photovoltaics ndi Thin-Film Energy Devices (SDU CAPE), idauza magazini ya pv, "Zida zathu pakuyesaku zinali 2.8 mm2 ndi 6.6 mm2, koma zitha kuwonjezeredwa mu labu yathu yosinthira ku SDU CAPE komwe timapanganso ma module a OPV."
Anagogomezera kuti njira yopangira ikhoza kuchepetsedwa, ponena kuti mawonekedwe osakanikirana ndi "otsika mtengo omwe amasungunuka m'madzi osungunulira wamba, kotero angagwiritsidwe ntchito popaka mphira-to-roll monga zigawo zina zonse" mu OPV cell.
Engmann amawona zowonjezera zowonjezera kupitirira OPV mu matekinoloje ena amtundu wachitatu, monga ma cell a solar a perovskite ndi ma cell a solar olimbikitsa utoto (DSSC). "Maukadaulo ena opangidwa ndi organic / hybrid semiconductor-based, monga DSSC ndi ma cell a solar a perovskite, ali ndi vuto lokhazikika lofanana ndi ma cell a solar organic, kotero pali mwayi woti athandizire kuthetsa mavuto okhazikika muukadaulo uwu," adatero.
Selo idawonetsedwa mu pepala "Vitamini C wa Maselo a Solar Solar Okhazikika Osakhazikika Osadzaza-kulandila,” lofalitsidwa muACS Applied Material Interfaces.Wolemba woyamba wa pepalali ndi SDU CAPE's Sambathkumar Balasubramanian. Gululi linaphatikizapo ofufuza a SDU ndi Rey Juan Carlos University.
Kuyang'ana m'tsogolo gululi lili ndi mapulani opitilira kafukufuku wokhudzana ndi njira zokhazikika pogwiritsa ntchito ma antioxidants omwe amapezeka mwachilengedwe. "M'tsogolomu, tipitilizabe kufufuza mbali iyi," adatero Engmann ponena za kafukufuku wolonjeza pa gulu latsopano la antioxidants.
