Tseeb AFM Los Ntawm Byungwoo Park, Seoul National University: Ob-sided Passivation Ntawm Perovskite Hnub Ci Cell Rau Kev Ua Haujlwm Siab Thiab Kev Ruaj Ntseg

Perovskite solar cells tau cog lus tias yuav muaj zog txuas ntxiv dua tshiab vim lawv cov khoom zoo nkauj. Txawm li cas los xij, lawv ntsib cov teeb meem hauv cov ntsiab lus ntawm kev hloov pauv hluav taws xob thiab kev ruaj ntseg mus sij hawm ntev. Lub xub ntiag ntawm qhov tsis xws luag nyob rau hauv perovskite hnub ci hlwb yog ib qho teeb meem tseem ceeb rau kev ua tiav kev ua haujlwm siab thiab ruaj khov, vim tias cov teeb meem no tuaj yeem ua rau nonradiative recombination thiab degradation. Raws li qhov no, Seoul National University Byungwoo Park & ​​Suwon University Jinhyun Kim tau luam tawm cov kev tshawb fawb ntawm ob tog passivation ntawm perovskite hnub ci hlwb kom ua tiav kev ua haujlwm siab thiab ruaj khov ntawm AFM thaum lub Cuaj Hlis 12, 2023, siv phenyltrimethyl iodide Ib qho tshiab ob sab. Txoj kev ua pa saum npoo av siv ammonium (PTMAI) ntsev kom tshem tawm cov teeb meem hluav taws xob zoo. Tsis tas li ntawd, PTMAI ob-sided passivation pab txhim kho perovskite crystallinity thiab so kom tsis sib xws ntawm cov kab mob hauv zos. Thaum kawg, los ntawm PTMAI ob-sided passivation, qhov ua tau zoo ntawm perovskite hnub ci hlwb tau txhim kho, ncav cuag qhov ua tau zoo ntawm 21.87%. Tsis tas li ntawd, cov hlwb passivated tau pom tias muaj kev ruaj ntseg mus ntev, khaws ntau dua 80% ntawm qhov pib ua haujlwm tom qab 1860 teev thiab 1030 teev ntawm 60 degree thiab 1 hnub, feem.

Ua kom koj lub zog cia daws teeb meem nrog peb Aluminium Roj Teeb Casing. Tsim los rau kev ua tau zoo thiab kev ua haujlwm ntev, ib yam li qhov kev sib tw tshiab hauv perovskite hnub ci hlwb. Txhawb koj cov peev txheej huv zog nrog kev ua tau zoo thiab ruaj khov. Xaiv peb lub casing rau lub neej yav tom ntej.
