Titanium Dioxide hmoov rau kev siv hnub ci Cell

Titanium dioxide hmoov feem ntau yog siv los ua cov khoom tseem ceeb hauv kev tsim cov dye-sensitized solar cells (DSSCs), tseem hu ua Grätzel hlwb. Cov hmoov yog siv los ua ib zaj duab xis nyias mus rau saum npoo ntawm lub hnub ci, qhov uas nws ua raws li photoanode uas pab nqus lub teeb thiab tsim hluav taws xob. Kev siv cov titanium dioxide hauv DSSCs tau txais txiaj ntsig vim nws cov khoom siv hluav taws xob muaj zog, tsis muaj tshuaj lom, thiab siv tau zoo.

Kev siv:

TiO2 yog siv los ua cov khoom siv semiconductor hauv kev tsim cov hnub ci hlwb. Nws yog ib qho tseem ceeb ntawm cov photoanode, uas yog cov txheej txheem uas absorbs tshav ntuj thiab pib cov txheej txheem hloov hluav taws xob uas tsim hluav taws xob.

TiO2 kuj tseem siv rau hauv kev tsim cov dye-sensitized solar cells (DSSC) thiab perovskite solar cells (PSC), uas yog hom tshiab thiab ntau dua ntawm cov hnub ci hnub ci.

Nta:

TiO2 yog cov hmoov dawb, tsis muaj ntxhiab, thiab tsis muaj tshuaj lom uas yog insoluble hauv dej thiab feem ntau cov kuab tshuaj organic.

Nws muaj qhov ntsuas siab refractive, uas txhais tau hais tias nws muaj peev xwm tawg thiab cuam tshuam lub teeb zoo.

TiO2 kuj yog ib qho hluav taws xob zoo insulator, ua rau nws haum rau siv nyob rau hauv photoanode txheej ntawm lub hnub ci hlwb.
