Fraunhofer ISE dị na Germany na-etinye teknụzụ obibi akwụkwọ FlexTrail ya na nhazi nke mkpụrụ ndụ anyanwụ nke silicon heterojunction.Ọ na-ekwu na nkà na ụzụ na-ebelata iji ọlaọcha mee ihe ma na-ejigide ọkwa dị elu nke arụmọrụ.
Ndị na-eme nchọpụta na Fraunhofer Institute for Solar Energy Systems (ISE) na Germany ewepụtala usoro a na-akpọ "FlexTrail Printing," usoro maka ibipụta mkpụrụ ndụ silicon heterojunction (SHJ) nke dabeere na ọlaọcha nanoparticles na-enweghị ụgbọ ala.N'ihu electrode plating usoro.
"Ugbu a, anyị na-emepụta isi akwụkwọ mbipụta FlexTrail nke nwere ike ịhazi mkpụrụ ndụ anyanwụ dị elu ngwa ngwa, ntụkwasị obi na n'ụzọ ziri ezi," onye nchọpụta Jörg Schube gwara pv."Ebe ọ bụ na oriri mmiri dị ntakịrị, anyị na-atụ anya na ngwọta fotovoltaic ga-enwe mmetụta dị mma na ọnụahịa na gburugburu ebe obibi."
Mbipụta FlexTrail na-enye ohere maka ngwa ngwa nke ngwa viscosities dị iche iche nwere obosara nhazi kacha nta nke ọma.
Ndị ọkà mmụta sayensị ahụ kwuru, "Egosikwara na ọ na-enye iji ọlaọcha rụọ ọrụ nke ọma, otu kọntaktị, yana oriri ọlaọcha dị ala.""Ọ nwekwara ike ibelata oge okirikiri n'otu sel n'ihi ịdị mfe na nkwụsi ike nke usoro ahụ, ya mere a na-ezubere ya maka mbufe n'ọdịnihu site na ụlọ nyocha."gaa factory".
Usoro a gụnyere iji capillary iko na-agbanwe nke ukwuu nke jupụtara na mmiri mmiri na nrụgide ikuku ruo 11 mmanya.N'oge usoro obibi akwụkwọ, capillary na-akpakọrịta na mkpụrụ ma na-aga n'ihu na ya.
"Mgbanwe mgbanwe na mgbanwe nke capillaries iko na-enye ohere maka nhazi nke na-adịghị emebi emebi," ndị ọkà mmụta sayensị kwuru, na-ekwupụta na usoro a na-enyekwa ohere ka e bipụta ihe owuwu gbagọrọ agbagọ."N'ịgbakwụnye, ọ na-eme ka ọ dị nro nke isi."
Ndị otu nyocha ahụ ji SmartWire Connection Technology (SWCT) rụpụtara modul batrị otu cell, teknụzụ njikọ njikọ ọtụtụ waya dabere na waya ọla kọpa nwere mkpuchi obere okpomọkụ.
“Ọtụtụ, a na-etinye wires ndị ahụ n'ime foil polymer ma jikọọ ya na sel anyanwụ site na iji eserese waya akpaaka.A na-etolite nkwonkwo solder na usoro lamination na-esote na okpomọkụ usoro dakọtara na silicon heterojunctions, "ndị nchọpụta kwuru.
N'iji otu capillary, ha na-ebipụta mkpịsị aka ha na-aga n'ihu, na-ebute ahịrị ọrụ dabere na ọlaọcha nwere nha nha 9µm.Ha wee wuo SHJ anyanwụ cell na arụmọrụ nke 22.8% na M2 wafers wee jiri mkpụrụ ndụ ndị a mee 200mm x 200mm otu modul cell.
