Fraunhofer ISE kuGermany iri kushandisa yayo FlexTrail kudhinda tekinoroji kune yakananga metallization yesilicon heterojunction solar maseru.Iyo inotaura kuti tekinoroji inoderedza kushandiswa kwesirivheri uchichengetedza huwandu hwepamusoro hwekuita.
Vatsvakurudzi veFraunhofer Institute for Solar Energy Systems (ISE) kuGermany vakagadzira nzira inonzi "FlexTrail Printing," nzira yekudhinda silicon heterojunction (SHJ) masero ezuva anobva pane sirivheri nanoparticles pasina bhasi.Front electrode plating nzira.
"Isu tiri kugadzira yakafanana FlexTrail printhead iyo inogona kugadzirisa yakakwirira-yezuva maseru nekukurumidza, nekuvimbika uye nemazvo," muongorori Jörg Schube akaudza pv."Sezvo kushandiswa kwemvura kwakaderera zvikuru, tinotarisira kuti photovoltaic solution ive nemigumisiro yakanaka pamutengo uye kukanganisa kwezvakatipoteredza."
Kudhinda kweFlexTrail kunobvumira kunyatso shandiswa kwezvinhu zvemhando dzakasiyana-siyana dzemaviscosities ane yakanyatsojeka mashoma chimiro upamhi.
"Zvakaratidzwa kuti zvinopa kushandiswa kwakanaka kwesirivha, kufanana kwekubatana, uye kushandiswa kwesirivha kwakaderera," masayendisiti akadaro."Iyo zvakare ine mukana wekudzikisa nguva dzekutenderera pasero nekuda kwekureruka uye kugadzikana kwemaitiro, uye nekudaro inoitirwa kutamiswa kweramangwana kubva murabhu."kufekitari”.
Iyi nzira inosanganisira kushandiswa kwegirazi rakatetepa rinochinjika capillary rakazadzwa nemvura pamhepo yemhepo kusvika ku11 bar.Panguva yekudhinda, iyo capillary inosangana ne substrate uye inofamba ichienderera mberi nayo.
"Kuchinjika uye kuchinjika kwegirazi capillaries kunobvumira kusaparadza kugadziridzwa," akadaro masayendisiti, achicherechedza kuti nzira iyi inobvumirawo zvimiro zvakakomberedzwa kuti zvidhindwe."Pamusoro pezvo, inoenzanisa kubhururuka kunogona kuita base."
Chikwata chekutsvagisa chakagadzira single-cell bhatiri module uchishandisa SmartWire Connection Technology (SWCT), yakawanda-waya yekubatanidza tekinoroji yakavakirwa pazasi-tembiricha solder-yakavharidzirwa waya dzemhangura.
"Kazhinji, waya dzinosanganiswa mupolymer foil uye dzakabatanidzwa kune solar maseru uchishandisa otomatiki waya yekudhirowa.Iwo majoini anotengeswa anoumbwa mune inotevera lamination process pakudziya tembiricha inoenderana nesilicon heterojunctions, "vanoongorora vanodaro.
Vachishandisa capillary imwe chete, vakaramba vachidhinda zvigunwe zvavo, zvichikonzera mitsara yesirivha-based ine saizi ye9 µm.Vakazovaka SHJ solar masero ane hunyanzvi hwe22.8% paM2 wafers uye vakashandisa maseru aya kugadzira 200mm x 200mm single cell modules.
Iyo pani yakawana simba rekushandura simba re19.67%, yakavhurika yedunhu voltage ye731.5 mV, pfupi dunhu ikozvino 8.83 A, uye basa kutenderera kwe74.4%.Kana tichienzanisa, iyo skrini-yakadhindwa referensi module ine hunyanzvi hwe20.78%, yakavhurika yedunhu voltage ye733.5 mV, pfupi yedunhu ikozvino ye8.91 A, uye yebasa cycle ye77.7%.
"FlexTrail ine mabhenefiti pamusoro peinkjet maprinta maererano neshanduko inoshanda.Mukuwedzera, ine mukana wekuve nyore uye naizvozvo kuwedzera kwehupfumi kubata, sezvo chigunwe chimwe nechimwe chinongoda kudhindwa kamwe chete, uye nekuwedzera, kushandiswa kwesirivha kuduku.yakaderera, vatsvakurudzi vakati, vachiwedzera kuti kuderera kwesirivha kunofungidzirwa kuva kwakapoteredza 68 muzana.
Vanopa zvavakawana mupepa "Direct Low Silver Consumption FlexTrail Metallization yeHeterojunction Silicon Solar Cells: Kuongorora Kuitwa kweSolar Cells uye Modules" ichangobva kubudiswa mumagazini Energy Technology.
"Kuitira kugadzira nzira yekushandiswa kwemaindasitiri kweFlexTrail kudhinda, musoro weprinta wakafanana uri kugadzirwa parizvino," anopedzisa kudaro musayendisiti."Munguva pfupi iri kutevera, yakarongwa kuishandisa kwete chete kuSHD metallization, asiwo kune tandem solar maseru, senge perovskite-silicon tandem."
