Fraunhofer ISE ku Germany ikugwiritsa ntchito ukadaulo wake wosindikizira wa FlexTrail pakupanga zitsulo mwachindunji za silicon heterojunction solar cell.Imanena kuti ukadaulo umachepetsa kugwiritsa ntchito siliva ndikusunga magwiridwe antchito apamwamba.
Ofufuza a Fraunhofer Institute for Solar Energy Systems (ISE) ku Germany apanga njira yotchedwa FlexTrail Printing, njira yosindikizira ma cell a silicon heterojunction (SHJ) siliva nanoparticle solar popanda basi.Front electrode plating njira.
"Pakadali pano tikupanga chosindikizira chofananira cha FlexTrail chomwe chimatha kukonza ma cell a dzuwa mwachangu, modalirika komanso molondola," wofufuza Jörg Schube adauza pv."Popeza kuti kumwa kwamadzi kumakhala kochepa kwambiri, tikuyembekeza kuti njira ya photovoltaic ikhale ndi zotsatira zabwino pa mtengo ndi chilengedwe."
Kusindikiza kwa FlexTrail kumalola kugwiritsa ntchito molondola zida za ma viscosity osiyanasiyana okhala ndi makulidwe olondola kwambiri.
"Zawonetsedwa kuti zimapereka kugwiritsa ntchito bwino siliva, kuyanjana, komanso kugwiritsa ntchito siliva," adatero asayansi."Ilinso ndi mwayi wochepetsera nthawi yozungulira pa selo iliyonse chifukwa cha kuphweka kwake komanso kukhazikika kwa ndondomeko, chifukwa chake imayenera kusamutsidwa mtsogolo kuchokera ku labotale kupita kufakitale.
Njirayi imaphatikizapo kugwiritsa ntchito kapilari kakang'ono kakang'ono kakang'ono kakang'ono ka galasi kodzaza ndi madzi mumlengalenga mpaka 11 bar.Panthawi yosindikiza, capillary imakhudzana ndi gawo lapansi ndipo imayenda mosalekeza.
"Kusinthasintha komanso kusinthasintha kwa ma capillaries agalasi kumapangitsa kuti pakhale kusawononga," adatero asayansi, pozindikira kuti njirayi imalolanso kuti zida zopindika zisindikizidwe."Kuphatikiza apo, imalinganiza kugwedezeka kwa maziko."
Gulu lofufuzira linapanga ma module a batri a cell imodzi pogwiritsa ntchito SmartWire Connection Technology (SWCT), teknoloji yolumikizira mawaya ambiri yotengera mawaya amkuwa otsika kwambiri opangidwa ndi solder.
"Nthawi zambiri, mawayawa amaphatikizidwa muzojambula za polima ndikulumikizidwa ndi ma cell a dzuwa pogwiritsa ntchito waya wojambula.Malumikizidwe a solder amapangidwa munjira yotsatizana ndi kutentha komwe kumayenderana ndi ma silicon heterojunctions, "ofufuzawo akutero.
Pogwiritsa ntchito capillary imodzi, amasindikiza zala zawo mosalekeza, zomwe zimapangitsa kuti mizere yogwiritsira ntchito siliva ikhale ndi mawonekedwe a 9 µm.Kenako adapanga ma cell a solar a SHJ okhala ndi mphamvu ya 22.8% pa zowotcha za M2 ndipo adagwiritsa ntchito ma cellwa kupanga ma module a cell 200mm x 200mm.
Gululi lidapeza mphamvu yosinthira mphamvu ya 19.67%, voliyumu yotseguka ya 731.5 mV, njira yayifupi ya 8.83 A, ndi kuzungulira kwa 74.4%.Mosiyana ndi izi, mawonekedwe osindikizira a skrini ali ndi mphamvu ya 20.78%, magetsi otseguka a 733.5 mV, afupipafupi a 8.91 A, ndi ntchito yozungulira 77.7%.
"FlexTrail ili ndi maubwino kuposa osindikiza a inkjet pakusintha bwino.Kuonjezera apo, ili ndi ubwino wokhala wosavuta komanso wokwera mtengo kwambiri, popeza chala chilichonse chimangofunika kusindikizidwa kamodzi, komanso, kugwiritsa ntchito siliva kumakhala kochepa.m'munsi, ofufuzawo adanena, ndikuwonjezera kuti kuchepa kwa siliva kumakhala pafupifupi 68 peresenti.
Anapereka zotsatira zawo mu pepala lotchedwa "Direct FlexTrail Plating ndi Low Silver Consumption for Heterojunction Silicon Solar Cells: Kuyesa Magwiridwe a Maselo a Solar ndi Ma modules" posachedwapa lofalitsidwa m'magazini ya Energy Technology.
"Pofuna kukonza njira yogwiritsira ntchito mafakitale a FlexTrail kusindikiza, mutu wosindikizira wofanana ukupangidwa," akumaliza motero wasayansi."Posachedwapa, akukonzekera kuti azigwiritsa ntchito osati zitsulo za SHD zokha, komanso ma cell a solar tandem, monga perovskite-silicon tandem."
