Vatsvagiri veDanish vanoshuma kuti kurapa isiri-yakazara-yakavakirwa organic solar maseru ane vhitamini C inopa antioxidant chiitiko chinoderedza maitiro anoshatisa anobva mukupisa, chiedza, uye kuratidzwa kweokisijeni. Sero rakawana simba rekushandura simba re9.97%, yakavhurika-circuit voltage ye0.69 V, pfupi-circuit current density ye 21.57 mA/cm2, uye kuzadza 66%.
Chikwata chevaongorori kubva kuYunivhesiti yeSouthern Denmark (SDU) yakatsvaga kuenzanisa kufambira mberi kuri kuitwa mukushandurwa kwesimba kwe organic solar cell (OPV) yakagadzirwa ne.isiri-yakazara kugamuchira (NFA)zvinhu zvine kugadzikana kuvandudzwa.
Chikwata chakasarudza ascorbic acid, inowanzo zivikanwa sevhitamini C, uye yakaishandisa senge passivation layer pakati pe zinc oxide (ZnO) electron transport layer (ETL) uye photoactive layer yemuNFA OPV masero akagadzirwa ane inverted mudziyo layer stack uye semiconducting polymer (PBDB-T:IT-4F).
Masayendisiti akavaka sero ne indium tin oxide (ITO) layer, iyo ZnO ETL, iyo vhitamini C layer, PBDB-T: IT-4F absorber, molybdenum oxide (MoOx) inotakura-selective layer, uye sirivheri (Ag. ) kusangana nesimbi.
Boka racho rakaona kuti ascorbic acid inogadzira photostabilizing effect, ichitaura kuti antioxidant basa rinoderedza maitiro ekuora mwoyo anobva pakusangana neokisijeni, chiedza uye kupisa. Miedzo, senge ultraviolet-inooneka absorption, impedance spectroscopy, chiedza-inotsamira magetsi uye zviyero zvazvino, zvakaratidzawo kuti vhitamini C inoderedza kudhirowa kwemamorekuru eNFA uye inodzvanya kubhadharisa kudzokororwa, yakacherekedza tsvakiridzo.
Ongororo yavo yakaratidza kuti, mushure me96 h yekuenderera mberi kwekuora pasi peZuva 1, zvigadziriso zvakavharwa zvine vhitamini C interlayer zvakachengeta 62% yekukosha kwavo kwepakutanga, nemichina yekutarisa inongochengeta 36%.
Zvigumisiro zvakaratidzawo kuti kubudirira kwekugadzikana hakuna kuuya pamutengo wekushanda. Chishandiso cheshasha chakawana simba rekushandura simba re9.97%, yakavhurika-circuit voltage ye0.69 V, pfupi-circuit ikozvino density ye21.57 mA/cm2, uye inozadza chinhu che66%. Midziyo yereferensi isina vitamin C, yakaratidza 9.85 % kushanda zvakanaka, yakavhurika-circuit voltage ye0.68V, pfupi-circuit current ye21.02 mA/cm2, uye inozadza 68%.
Paakabvunzwa nezve kutengeserana kugona uye scalability, Vida Engmann anotungamira boka paCenter for Advanced Photovoltaics uye Thin-Film Energy Devices (SDU CAPE), akaudza pv magazine, "Midziyo yedu muchiyedzo ichi yaive 2.8 mm2 uye 6.6 mm2, asi inogona kukwidziridzwa muroll-to-roll lab kuSDU CAPE kwatinogara tichigadzira maOPV module zvakare."
Akasimbisa kuti nzira yekugadzira inogona kuyerwa, ichiratidza kuti iyo yemukati mese "isingadhure musanganiswa unonyungudika mune zvakajairwa zvinonyungudutsa, saka inogona kushandiswa mu roll-to-roll coating process senge mamwe ese" mu. OPV cell.
Engmann anoona mukana wekuwedzera kupfuura OPV mune mamwe echitatu-chizvarwa chesero tekinoroji, senge perovskite solar masero uye dhayi-sensitized solar maseru (DSSC). "Mamwe organic / hybrid semiconductor-based tekinoroji, akadai seDSSC uye perovskite solar masero, ane nyaya dzakafanana dzekugadzikana semasero ezuva, saka pane mukana wakanaka wekuti vabatsire mukugadzirisa matambudziko ekugadzikana mune aya matekinoroji zvakare," akadaro.
Chitokisi chakaiswa mubepa "Vitamin C yePhoto-Stable Non-fullerene-acceptor-Based Organic Solar Cells,” rakabudiswa munaACS Applied Material Interfaces.Munyori wekutanga webepa ndiSDU CAPE's Sambathkumar Balasubramanian. Chikwata ichi chaisanganisira vaongorori veSDU uye Rey Juan Carlos University.
Tichitarisa kumberi timu ine zvirongwa zvekumwe tsvagiridzo yenzira dzekudzikamisa vachishandisa zvinongoitika antioxidants. "Mune ramangwana, tichaenderera mberi nekuferefeta munzira iyi," akadaro Engmann achireva kuvimbisa kutsvagisa kwekirasi nyowani yema antioxidants.
