I-Fraunhofer ISE eJamani isebenzisa itekhnoloji yoshicilelo yeFlexTrail kwintsimbi ethe ngqo yeeseli ze-silicon heterojunction zelanga.Ithi iteknoloji iyanciphisa ukusetyenziswa kwesilivere ngelixa igcina inqanaba eliphezulu lokusebenza kakuhle.
Abaphandi beFraunhofer Institute for Solar Energy Systems (ISE) eJamani baye baqulunqa ubuchule obubizwa ngokuba yi "FlexTrail Printing," indlela yokushicilela iiseli zelanga ze-silicon heterojunction (SHJ) ezisekelwe kwi-nanoparticles yesilivere ngaphandle kwebhasi.Indlela yokubeka i-electrode yangaphambili.
"Okwangoku senza i-parallel FlexTrail printhead enokuthi isebenze iiseli zelanga eziphezulu ngokukhawuleza, ngokuthembekileyo nangokuchanekileyo," umphandi uJörg Schube uxelele pv."Ekubeni ukusetyenziswa kwamanzi kuphantsi kakhulu, silindele ukuba isisombululo se-photovoltaic sibe nefuthe elihle kwiindleko kunye nefuthe lokusingqongileyo."
Ushicilelo lwe-FlexTrail luvumela usetyenziso oluchanekileyo lwemathiriyeli yee-viscosities ezahlukeneyo ezinobubanzi obuchanekileyo obuchanekileyo.
"Kuye kwaboniswa ukubonelela ngokusetyenziswa kwesilivere okusebenzayo, ukufana okufanayo, kunye nokusetyenziswa kwesilivere ephantsi," izazinzulu zatsho."Ikwanamandla okunciphisa amaxesha omjikelo kwiseli nganye ngenxa yokulula kunye nokuzinza kwenkqubo, kwaye kungoko ijongwe kudluliselo lwexesha elizayo kwilebhu."kumzi mveliso”.
Le ndlela ibandakanya ukusetyenziswa kwe-capillary yeglasi ethambileyo kakhulu eguquguqukayo ezaliswe lulwelo kuxinzelelo lwe-atmospheric ukuya kuthi ga kwi-11 bar.Ngethuba lenkqubo yokushicilela, i-capillary idibanisa ne-substrate kwaye ihamba ngokuqhubekayo kunye nayo.
"Ukuguquguquka kunye nokuguquguquka kwee-capillaries zeglasi kuvumela ukuqhutyelwa kokungonakalisi," izazinzulu zathi, ziphawula ukuba le ndlela ivumela ukuba izakhiwo ezigobileyo ziprintwe."Ukongezelela, ilinganisa ukushukuma okunokwenzeka kwesiseko."
Iqela lophando lenze iimodyuli zebhetri enye-cell usebenzisa i-SmartWire Connection Technology (SWCT), iteknoloji ye-multi-wire interconnect technology esekelwe kwi-low-temperature-coated copper copper.
Ngokuqhelekileyo, iingcingo zihlanganiswe kwi-polymer foil kwaye zixhunywe kwiiseli zelanga zisebenzisa umzobo wocingo oluzenzekelayo.Amalungu e-solder ayenziwa kwinkqubo yokulahla i-lamination elandelayo kwiqondo lokushisa elihambelana ne-silicon heterojunctions, "abaphandi bathi.
Besebenzisa i-capillary enye, baqhubeka beprinta iminwe yabo, okukhokelela kwimigca esebenzayo esekwe kwisilivere enobukhulu obuyi-9 µm.Emva koko baye bakha iiseli zelanga ze-SHJ ngokusebenza kakuhle kwe-22.8% kwii-wafers ze-M2 kwaye basebenzisa ezi seli ukwenza i-200mm x 200mm iimodyuli zeseli enye.
Iphaneli iphumelele ukuguqulwa kwamandla okusebenza kakuhle kwe-19.67%, i-voltage yesekethe evulekileyo ye-731.5 mV, i-short circuit current ye-8.83 A, kunye nomjikelo womsebenzi we-74.4%.Ngokuthelekisa, imodyuli yereferensi eprintiweyo yesikrini inokusebenza kakuhle kwe-20.78%, i-voltage yesiphaluka evulekileyo ye-733.5 mV, i-short circuit current ye-8.91 A, kunye nomjikelezo womsebenzi we-77.7%.
“I-FlexTrail ineengenelo ngaphezulu kweeprinta ze-inkjet ngokwemigaqo yoguqulo olusebenzayo.Ukongezelela, kunenzuzo yokuba lula kwaye ngoko ke ukonga ngakumbi ukuphatha, ekubeni umnwe ngamnye ufuna ukuprintwa kanye kuphela, kwaye ukongezelela, ukusetyenziswa kwesilivere kuncinci.esezantsi, abaphandi bathi, bongeza ukuba ukuhla kwesilivere kuqikelelwa ukuba malunga 68 ekhulwini.
Babonisa iziphumo zabo kwiphepha elithi "I-Direct Low Silver Consumption FlexTrail Metallization ye-Heterojunction Silicon Solar Cells: Ukuvavanya ukuSebenza kweeSeli zeSolar kunye neeModyuli" kutshanje ipapashwe kwiphephancwadi i-Energy Technology.
"Ukuze kulungiswe indlela yokusetyenziswa kweshishini lokuprinta i-FlexTrail, ngoku kuphuhliswa intloko yokuprinta ehambelanayo," iqukumbela inzululwazi.Kwixesha elizayo elingekude, kucetywa ukuyisebenzisela kungekuphela nje i-SHD metallization, kodwa nakwiiseli zelanga ze-tandem, ezifana ne-perovskite-silicon tandem.
