I-Fraunhofer ISE yaseJalimane isebenzisa ubuchwepheshe bayo bokuphrinta be-FlexTrail ekwenzeni insimbi eqondile yamaseli elanga e-silicon heterojunction.Ithi ubuchwepheshe bunciphisa ukusetshenziswa kwesiliva ngenkathi kugcinwa izinga eliphezulu lokusebenza kahle.
Abacwaningi e-Fraunhofer Institute for Solar Energy Systems (ISE) eJalimane benze indlela ebizwa ngokuthi “FlexTrail Printing,” indlela yokunyathelisa amaseli elanga e-silicon heterojunction (SHJ) asekelwe ku-nanoparticles esiliva ngaphandle kwebha yebhasi.Indlela yokufaka i-electrode yangaphambili.
"Njengamanje senza i-parallel FlexTrail printhead engakwazi ukucubungula amaseli elanga asebenza kahle kakhulu ngokushesha, ngokuthembekile nangokunembile," umcwaningi uJörg Schube etshela i-pv."Njengoba ukusetshenziswa kwamanzi kuphansi kakhulu, silindele ukuthi isisombululo se-photovoltaic sibe nomthelela omuhle ezindleko kanye nomthelela wemvelo."
Ukuphrinta kwe-FlexTrail kuvumela ukusetshenziswa okunembayo kwezinto zokwakha ezihlukahlukayo ezinobubanzi obuncane obunembe ngokwedlulele besakhiwo.
"Kukhonjiswe ukuthi kuhlinzeka ngokusetshenziswa kahle kwesiliva, ukufana kokuxhumana, kanye nokusetshenziswa kwesiliva okuphansi," kusho ososayensi."Futhi inamandla okunciphisa izikhathi zomjikelezo ngeseli ngalinye ngenxa yobulula nokuzinza kwenqubo, yingakho ihloselwe ukudluliselwa okuzayo kusuka elebhu."efektri”.
Le ndlela ihilela ukusetshenziswa kwe-capillary yengilazi encane kakhulu eguquguqukayo egcwele uketshezi ekucindezelweni komkhathi kuze kufike ku-11 bar.Phakathi nenqubo yokunyathelisa, i-capillary ixhumana ne-substrate futhi ihamba ngokuqhubekayo kuyo.
"Ukuguquguquka nokuguquguquka kwama-capillaries engilazi kuvumela ukucutshungulwa okungabhubhisi," kusho ososayensi, bephawula ukuthi le ndlela ibuye ivumele izakhiwo ezigobile ukuthi ziphrintiwe."Ngaphezu kwalokho, ilinganisa ukuguquguquka okungenzeka kwesisekelo."
Ithimba labacwaningi lenze amamojula ebhethri yeseli elilodwa lisebenzisa i-SmartWire Connection Technology (SWCT), ubuchwepheshe bokuxhumanisa izintambo eziningi obusekelwe ezintanjeni zethusi ezinamazinga okushisa aphansi ezimbozwe nge-solder.
"Ngokujwayelekile, izintambo zihlanganiswa ku-polymer foil futhi zixhunywe kumaseli elanga kusetshenziswa umdwebo wezintambo ezizenzakalelayo.Amalunga e-solder akhiwa ngenqubo elandelayo yokulahlwa emazingeni okushisa enqubo ahambisana ne-silicon heterojunctions, "kusho abacwaningi.
Besebenzisa i-capillary eyodwa, baqhubeka bephrinta iminwe yabo, okuholela emigqeni yokusebenza esekelwe esiliva enosayizi wesici ongu-9 µm.Babe sebekha amaseli elanga e-SHJ ngokusebenza kahle okungu-22.8% kumawafa e-M2 futhi basebenzisa lawa maseli ukwenza amamojula eseli elilodwa angu-200mm x 200mm.
Iphaneli ithole ukusebenza kahle kokuguqulwa kwamandla okungu-19.67%, ivolthi yesekethe evulekile engu-731.5 mV, isifunda esifushane esingu-8.83 A, kanye nomjikelezo wemisebenzi ongu-74.4%.Uma kuqhathaniswa, imojula yereferensi ephrintiwe isikrini isebenza kahle ngo-20.78%, i-voltage yesifunda evulekile engu-733.5 mV, i-current circuit short engu-8.91 A, kanye nomjikelezo womsebenzi ongu-77.7%.
“I-FlexTrail inezinzuzo ngaphezu kwamaphrinta e-inkjet ngokusebenza kahle kokuguqula.Ngaphezu kwalokho, kunenzuzo yokuba lula futhi ngakho-ke ukonga kakhulu ukuphatha, ngoba umunwe ngamunye udinga ukuphrinta kanye kuphela, futhi ngaphezu kwalokho, ukusetshenziswa kwesiliva kuncane.ephansi, kusho abacwaningi, enezela ukuthi ukwehla kwesiliva kulinganiselwa ukuthi cishe ngamaphesenti angu-68.
Bethula abakutholile ephepheni elithi “Direct Low Silver Consumption FlexTrail Metallization for Heterojunction Silicon Solar Cells: Evaluating the Performance of Solar Cells and Modules” esanda kushicilelwa kumagazini I-Energy Technology.
“Ukuze kuvulwe indlela yokusetshenziswa kwezimboni zokunyathelisa i-FlexTrail, okwamanje kwakhiwa inhloko yokuphrinta ehambisanayo,” kuphetha usosayensi."Maduze nje, ihlelelwe ukuthi ingayisebenziseli ukwenza insimbi ye-SHD kuphela, kodwa futhi namaseli elanga e-tandem, njenge-perovskite-silicon tandem."

Ngokuthumela leli fomu, uyavumelana nokusetshenziswa kwedatha yakho ngumagazini we-pv ukushicilela amazwana akho.
Idatha yakho siqu izodalulwa kuphela noma kwabelwane ngayo nabantu besithathu ngezinjongo zokuhlunga ogaxekile noma njengoba kudingekile ukuze kugcinwe iwebhusayithi.Akukho okunye ukudluliselwa okuzokwenziwa kubantu besithathu ngaphandle uma kuthethelelwa imithetho esebenzayo yokuvikela idatha noma imagazini ye-pv idingwa ngumthetho ukwenza kanjalo.
Ungahoxisa le mvume noma kunini ngokuzayo, lapho idatha yakho yomuntu siqu izosuswa ngokushesha.Uma kungenjalo, idatha yakho izosuswa uma i-pv log isicubungule isicelo sakho noma injongo yokulondoloza idatha ifinyelelwe.
Izilungiselelo zekhukhi kule webhusayithi zisethelwe “ukuvumela amakhukhi” ukukunikeza umuzwa ongcono kakhulu wokuphequlula.Uma uqhubeka nokusebenzisa lesi sizindalwazi ngaphandle kokushintsha izilungiselelo zakho zekhukhi noma uchofoze okuthi “Yamukela” ngezansi, uyavumelana nalokhu.
