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 basungule indlela ebizwa nge-FlexTrail Printing, indlela yokuphrinta amaseli elanga e-silicon heterojunction (SHJ) esiliva nanoparticle ngaphandle kwebhasi.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 isikhathi somjikelezo ngeseli ngalinye ngenxa yobulula bayo kanye nokuzinza kwenqubo, futhi yingakho ihloselwe ukudluliselwa kwesikhathi esizayo kusuka ezindaweni zokucwaninga kuya efemini.
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%.Ngokuphambene, imojula yereferensi ephrintiwe isikrini isebenza kahle ngo-20.78%, i-voltage yesekethe evulekile engu-733.5 mV, isifunda esifushane samanje esingu-8.91 A, kanye nomjikelezo wemisebenzi 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.
Bethule imiphumela yabo ephepheni elithi “Direct FlexTrail Plating with Low Silver Consumption 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 i-metallization 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 i-pv idingwa ngumthetho ukwenza kanjalo.
