Ke hoʻohana nei ʻo Fraunhofer ISE ma Kelemania i kāna ʻenehana paʻi FlexTrail i ka metallization pololei o nā cell solar heterojunction silicon.Ua'ōleloʻia e ho'ēmi kaʻenehana i ka hoʻohanaʻana i ke kālā me ka mālamaʻana i kahi kiʻekiʻe o ka pono.
Ua hoʻomohala ka poʻe noiʻi ma ka Fraunhofer Institute for Solar Energy Systems (ISE) ma Kelemānia i kahi ʻenehana i kapa ʻia ʻo "FlexTrail Printing," kahi ala no ka paʻi ʻana i nā cell solar heterojunction (SHJ) ma muli o nā nanoparticles kālā me ka ʻole o ka busbar.ʻO ke ʻano hoʻopalapala electrode mua.
"Ke hoʻomohala nei mākou i kēia manawa i kahi paʻi paʻi FlexTrail e hiki ke hoʻoponopono wikiwiki i nā cell solar kiʻekiʻe, hilinaʻi a pololei," wahi a ka mea noiʻi ʻo Jörg Schube i ka pv."Ma muli o ka haʻahaʻa loa o ka inu wai, manaʻo mākou e loaʻa i ka hopena photovoltaic ka hopena maikaʻi i ke kumukūʻai a me ka hopena o ke kaiapuni."
ʻO ka paʻi ʻana iā FlexTrail e hiki ke hoʻohana pololei i nā mea o nā ʻano viscosities me nā laulā haʻahaʻa liʻiliʻi loa.
"Ua hōʻike ʻia e hāʻawi i ka hoʻohana kālā maikaʻi ʻana, ka hoʻopili like ʻana, a me ka hoʻohana kālā haʻahaʻa," i ʻōlelo ai nā ʻepekema."Loaʻa iā ia ka hiki ke hōʻemi i nā manawa pōʻai i kēlā me kēia cell ma muli o ka maʻalahi a me ka paʻa o ke kaʻina hana, a no laila ua manaʻo ʻia no ka neʻe ʻana mai ka lab."i ka hale hana”.
Hoʻohana ʻia kēia ʻano hana i ka capillary aniani hikiwawe loa i hoʻopiha ʻia me ka wai ma ke kaomi lewa a hiki i ka 11 bar.I ka wā o ka paʻi ʻana, pili ka capillary me ka substrate a neʻe mau i laila.
"ʻO ka maʻalahi a me ka maʻalahi o nā capillaries aniani e hiki ai i ka hana hoʻopōʻino ʻole," i ʻōlelo ʻia e nā ʻepekema, me ka ʻike ʻana e hiki ai i kēia ʻano hana ke paʻi ʻia."Eia kekahi, ke kaupaona nei i ka waviness o ke kumu."
Ua hana ka hui noiʻi i nā modula pākahi pākahi me ka hoʻohana ʻana i ka SmartWire Connection Technology (SWCT), kahi ʻenehana hoʻohui i nā uea nui ma muli o nā uea keleawe haʻahaʻa solder-coated.
"ʻO ka maʻamau, hoʻohui ʻia nā uea i loko o ka polymer foil a hoʻopili ʻia i nā cell solar me ka hoʻohana ʻana i ke kaha kiʻi uea.Hoʻokumu ʻia nā hui solder i kahi kaʻina lamination ma hope o ke kaʻina hana i kūpono me nā heterojunctions silicon, "wahi a nā mea noiʻi.
Me ka hoʻohana ʻana i ka capillary hoʻokahi, paʻi mau lākou i ko lākou mau manamana lima, e loaʻa ana i nā laina hana kālā me kahi hiʻohiʻona o 9 µm.A laila kūkulu lākou i ka SHJ solar cell me ka maikaʻi o 22.8% ma nā wafers M2 a hoʻohana i kēia mau cell e hana i 200mm x 200mm single cell modules.
Ua loaʻa i ka panel ka mana hoʻololi mana o 19.67%, kahi hāmama kaapuni uila o 731.5 mV, kahi pōkole pōkole o 8.83 A, a me kahi pōʻai hana o 74.4%.Ma ka hoʻohālikelike ʻana, loaʻa ka pono o ka module kuhikuhi i paʻi ʻia i ka pale he 20.78%, kahi uila kaapuni hāmama o 733.5 mV, kahi manawa pōkole pōkole o 8.91 A, a me kahi pōʻai hana o 77.7%.
"He mau mea maikaʻi ʻo FlexTrail ma mua o nā mea paʻi inkjet ma ke ʻano o ka hoʻololi ʻana.Eia kekahi, loaʻa iā ia ka maʻalahi a no laila ʻoi aku ka maikaʻi o ka mālama ʻana, no ka mea, pono e paʻi ʻia kēlā me kēia manamana lima i hoʻokahi manawa, a ʻoi aku ka liʻiliʻi o ka ʻai kālā.haʻahaʻa, ʻōlelo ka poʻe noiʻi, me ka hoʻohui ʻana i ka emi ʻana o ke kālā i manaʻo ʻia ma kahi o 68 pakeneka.
Hōʻike lākou i kā lākou ʻike ma ka pepa "Direct Low Silver Consumption FlexTrail Metallization for Heterojunction Silicon Solar Cells: Evaluating the Performance of Solar Cells and Modules" i paʻi hou ʻia ma ka puke pai Energy Technology.
"I mea e wehe ai i ke ala no ka hoʻohana ʻana i ka ʻenehana paʻi FlexTrail, ke kūkulu ʻia nei kahi poʻo paʻi like ʻole," i hoʻopau ai ka ʻepekema."I ka wā e hiki mai ana, ua hoʻolālā ʻia e hoʻohana iā ia ʻaʻole wale no ka metallization SHD, akā no ka tandem solar cell, e like me ka perovskite-silicon tandem."
