Kev siv ntawm silicon carbide ceramics hauv photovoltaic teb

① Nws yog cov khoom siv tseem ceeb hauv kev tsim cov cell photovoltaic
Ntawm silicon carbide structural ceramics, kev lag luam photovoltaic ntawm silicon carbide nkoj txhawb nqa tau tsim nyob rau theem siab ntawm txoj kev vam meej, dhau los ua qhov kev xaiv zoo rau cov khoom siv tseem ceeb hauv cov txheej txheem ntawm cov cell photovoltaic, thiab nws cov kev xav tau hauv kev lag luam tau txais kev nyiam los ntawm kev lag luam. .

Tam sim no, lub nkoj txhawb nqa, lub thawv nkoj, cov yeeb nkab fittings, thiab lwm yam ua los ntawm quartz feem ntau yog siv, tab sis lawv raug txwv los ntawm cov khoom siv hauv tsev thiab thoob ntiaj teb high-purity quartz xuab zeb ntxhia pob zeb hauv av, thiab lub peev xwm ntau lawm yog me me. Muaj cov khoom siv nruj thiab kev thov rau high-purity quartz xuab zeb, thiab tus nqi tau khiav mus rau theem siab ntev, thiab kev pabcuam lub neej luv luv. Piv nrog cov ntaub ntawv quartz, kev txhawb nqa nkoj, lub thawv nkoj, cov yeeb nkab fittings thiab lwm yam khoom uas ua los ntawm cov khoom siv silicon carbide muaj cov thermal stability zoo, tsis muaj deformation ntawm qhov kub thiab txias, thiab tsis muaj kev puas tsuaj los ntawm cov pa phem. Raws li cov khoom siv zoo tshaj plaws rau cov khoom siv quartz, lub neej kev pabcuam tuaj yeem ncav cuag ntau tshaj 1 xyoos, uas tuaj yeem txo cov nqi siv thiab poob ntawm cov peev txheej tsim los ntawm kev saib xyuas thiab kho. Tus nqi kom zoo dua yog pom tseeb, thiab nws daim ntawv thov kev cia siab raws li tus neeg nqa khoom hauv thaj chaw photovoltaic yog dav.

② tuaj yeem siv los ua cov khoom siv hluav taws xob rau lub hnub ci hluav taws xob
Ntauwd hnub ci hluav taws xob hluav taws xob tsim hluav taws xob tau txais txiaj ntsig zoo hauv lub hnub ci tsim hluav taws xob vim tias lawv qhov sib piv siab (200 ~ 1000kW / ㎡), siab thermal voj voog kub, tsis tshua muaj cua sov, qhov system yooj yim thiab ua haujlwm siab. Raws li cov ntsiab lus tseem ceeb ntawm ntauwd hnub ci hluav taws xob hluav taws xob tsim hluav taws xob, lub tshuab nqus tsev yuav tsum tiv taus hluav taws xob siv 200-300 lub sij hawm muaj zog dua li lub teeb ntuj, thiab kev ua haujlwm kub tuaj yeem siab tshaj li ib txhiab degrees Celsius, yog li nws qhov kev ua haujlwm tseem ceeb heev. rau kev ua haujlwm ruaj khov thiab ua haujlwm ua haujlwm ntawm lub tshuab hluav taws xob thermal. Kev khiav hauj lwm kub ntawm cov khoom siv hlau tsoos yog txwv, ua rau cov khoom siv ceramic yog qhov kev tshawb fawb tshiab hotspot. Alumina ceramics, cordierite ceramics, thiab silicon carbide ceramics feem ntau yog siv los ua cov khoom siv absorber.

Hnub ci thermal fais fab chaw nres tsheb absorber ntauwd

Ntawm lawv, silicon carbide ceramics muaj cov yam ntxwv zoo xws li lub zog siab, thaj chaw loj tshwj xeeb, kev tiv thaiv corrosion, oxidation tsis kam, zoo thermal rwb thaiv tsev, thermal shock kuj thiab kub tsis kam. Piv nrog alumina thiab cordierite ceramic absorber cov ntaub ntawv, nws muaj kev ua haujlwm kub zoo dua. Kev siv lub tshuab nqus cua kub ua los ntawm sintered silicon carbide tso cai rau lub tshav kub absorber kom ncav cuag qhov hluav taws xob cua kub txog li 1200 ° C yam tsis muaj cov khoom puas.
