Ltalis tau tsim lub hnub ci module uas tuaj yeem tswj tau qhov ua tau zoo ntawm 90% ntawm 85 ° C

Taw qhia: Pab pawg tshawb fawb coj los ntawm Tor Vergata University hauv Rome, Ltalis tau tsim lub hnub ci peroxide nrog thaj tsam zoo ntawm 42.8 cm2 thiab thaj tsam aperture ntawm 50 square centimeters.Lub hnub ci vaj huam sib luag muaj 14 series ntawm peroxide roj teeb nrog 20% ​​efficiency nyob rau hauv series.Tom qab 800 teev ntawm thermal stress ntawm 85 ° C, nws tseem tuaj yeem tswj tau qhov ua tau zoo ntawm 90%.

Ib pab neeg tshawb fawb thoob ntiaj teb siv hom tshiab ntawm doping lub tswv yim los tsim ib lub hnub ci peroxide.Nws tau hais tias piv nrog rau lwm yam khoom siv peroxide, lub module tuaj yeem ua tiav kev ua haujlwm zoo dua thaum tswj xyuas qhov tseem ceeb ntawm kev ruaj ntseg ntawm kev ua haujlwm.

Txawm hais tias peroxide hnub ci hlwb zoo li nyob rau hauv txoj kev mus rau kev tsim khoom loj, tib neeg tseem txaus siab rau cov thev naus laus zis vim muaj kev txhawj xeeb txog kev ruaj ntseg ntawm qhov chaw thauj txheej (HTL) thiab nws qhov rhiab heev rau atmospheric tej yam kev mob.cuam ​​tshuam.

Cov kws tshawb fawb tau hais tias lawv tuaj yeem hloov qhov hnyav molecular (MW) ntawm lub qhov thauj khoom txheej (HTM) doped nrog polytriarylamine (PTAA).Lawv tau piav qhia: "Qhov kev nce ntawm monotonic hauv kev hloov pauv hluav taws xob ua haujlwm raws li kev ua haujlwm ntawm MW cuam tshuam nrog kev nce zoo sib xws hauv qhov qhib hluav taws xob qhib hluav taws xob (VOC), luv luv Circuit Court tam sim no (JSC), thiab qhov ua tiav (FF).Nyob rau hauv txoj kev no, tus nqi txav mus rau hauv HTL thiab tus nqi thauj khoom ntawm peroxide / HTL interface tau nce los ntawm qhov kev txiav txim loj. "

Lawv tau hais tias qhov kev txhim kho no tau ua tiav los ntawm kev sib xyaw ua ke ntawm doping lub tswv yim thiab MW tuning, uas tau ua tiav cov polaron dislocation ntawm cov saw hlau polymer.Kev tshawb fawb tshawb fawb tau taw qhia tias kev tsim cov polarons hauv cov hnub ci peroxide yog qhov ua tau uas ua rau cov roj teeb zoo li no, txawm tias cov txheej txheem tom qab cov polarons tsis paub meej.Ib tug poleon yog ib qho kev hloov pauv sai sai hauv cov atomic lattice ntawm cov khoom.Nws tsim nyob ib ncig ntawm ib qho hluav taws xob txav hauv ob peb trillionths ntawm ib thib ob, thiab tom qab ntawd ploj mus.

Nyob rau hauv lub hauv paus ntawm tag nrho cov zoo cheeb tsam ntawm 42.8 square centimeters thiab lub aperture cheeb tsam ntawm 50 square centimeters, 14 series ntawm peroxide roj teeb nrog 20% ​​efficiency yog txuas nrog nyob rau hauv series los tsim ib lub vaj huam sib luag nrog 17% efficiency.Qhov nce ntawm defocusing ncej nyob rau hauv HMW PTAA txheej tsis tsuas yog muab ib qho tseem ceeb pab rau lub siab efficiency ntawm lub cuab yeej, tab sis kuj muaj ib tug zoo ntxim rau cov peroxide lattice ntawm lub hauv paus txheej, yog li txhim kho nws tag nrho stability.Nws tau hais tias tom qab 1080 teev ntawm kev ntxhov siab thermal ntawm 85 degrees Celsius, lub roj teeb tseem tuaj yeem tswj tau qhov kev ua haujlwm pib ntawm ntau dua 90%, thiab tom qab 160 teev ntawm qhov raug, nws tseem tuaj yeem tswj tau qhov ua tau zoo ntawm 87%.Lub hnub ci vaj huam sib luag tseem tuaj yeem tswj tau qhov kev ua tau zoo ntawm ntau tshaj 90% tom qab 800 teev ntawm thermal stress ntawm 85 degrees Celsius.

Cov qauv no tau qhia nyob rau hauv daim ntawv "Kev ua tiav qhov ruaj khov perovskite-hom hnub ci module ntawm ntau dua 17% los ntawm kev hloov pauv ntawm cov polaron kev npaj ntawm polymer qhov chaw thauj txheej" luam tawm hauv "Nano Zog".Pab pawg tshawb fawb suav nrog cov kws tshawb fawb los ntawm Tor Vergata University hauv Rome, Ltalis, University College London, Cambridge University hauv UK, thiab Max Planck Lub Tsev Haujlwm rau Kev Tshawb Fawb Polymer hauv Tebchaws Yelemees.
