Vim li cas hnub ci hlwb thiaj li xiav xim?

Hnub ci silicon wafers tshwm xiav? Yuav kom meej meej, hnub ci hlwb tshwm xiav, thiab lawv yog polycrystalline hnub ci hlwb, thaum monocrystalline hnub ci hlwb feem ntau yog dub.

Qhov laj thawj yog vim li cas lawv xiav lossis xim dub yog vim qhov xim ntawd yog cov nyhuv ntawm Anti-reflected Txheej (anti-reflective txheej). Hnub ci vaj huam sib luag feem ntau nqus cov photons nyob ib ncig ntawm lub teeb ntsuab ntawm lub teeb pom kev, thaum lub hnub ci vaj huam sib luag yog xiav, uas txhais tau hais tias lub teeb pom kev yog ntawm xiav wavelength. Dub yog, ntawm chav kawm, tsis muaj kev cuam tshuam. Yog li dub yog qhov zoo tshaj plaws, xiav yog qhov zoo tshaj plaws thib ob.

Tam sim no muaj cov pigmented sensitized solar cell, uas yog ib lub xovtooj ntawm cov xim thiab electrolyte ntxiv ntawm ob lub substrates nrog pob tshab electrodes ntawm iav los yog yas substrate. Nrog rau cov thev naus laus zis no, pob tshab hlwb thiab cov hlwb ntawm ntau yam xim tuaj yeem tsim tau. Tsis muaj cov hlwb no ua haujlwm tau zoo, tab sis lawv pheej yig dua li cov silicon.

Ib qho kev tsim nyog hauv cov txheej txheem tsim khoom ntawm tes yog pecvd, lub hom phiaj ntawm kev tiv thaiv lub teeb ci ntsa iab (silicon nitride) kom txo cov txheej txheem teeb pom kev zoo, cov tuab ntawm cov txheej yog li 80um, vim yog cov khoom siv kho qhov muag ntawm silicon nitride zaj duab xis ua rau nws qhov chaw xiav.
