Hauv thaj chaw ntawm kev tsim hluav taws xob photovoltaic (PV), Plasma-Txhim kho Tshuaj Vapor Deposition (PECVD) thev naus laus zis ua lub luag haujlwm tseem ceeb. Hauv plawv ntawm cov txheej txheem no yog lub nkoj PECVD graphite, ib qho tseem ceeb tivthaiv uas cuam tshuam qhov zoo thiab kev ua haujlwm ntawm PV cell ntau lawm. Ib qho ntawm cov khoom tseem ceeb uas cuam tshuam rau kev ua haujlwm ntawm lub nkoj PECVD graphite yog nws cov hygroscopicity. Raws li ib tug ntseeg PECVD Graphite nkoj xa khoom, Kuv zoo siab los qhia rau hauv cov ncauj lus no thiab qhia cov kev nkag siab zoo.
Nkag siab Hygroscopicity
Hygroscopicity yog hais txog lub peev xwm ntawm cov khoom siv los nyiam thiab tuav cov dej molecules los ntawm ib puag ncig ib puag ncig. Cov cuab yeej no tseem ceeb tshwj xeeb hauv cov ntsiab lus ntawm PECVD graphite nkoj vim tias ya raws tuaj yeem cuam tshuam rau lawv qhov kev ua tau zoo. Thaum lub nkoj graphite nqus dej noo, nws tuaj yeem ua rau muaj ntau yam teeb meem thaum lub sijhawm PECVD txheej txheem.
Cov dej noo hauv lub nkoj graphite tuaj yeem ua rau cua sov thiab txias tsis sib xws, uas tuaj yeem ua rau thermal stress thiab tawg. Tsis tas li ntawd, lub xub ntiag ntawm cov dej molecules tuaj yeem hnov mob nrog cov txheej txheem gases hauv PECVD chamber, ua rau cov khoom tsis xav tau los ntawm - cov khoom. Cov no los ntawm - cov khoom tuaj yeem paug cov silicon wafers ua tiav, txo qhov ua tau zoo thiab zoo ntawm PV hlwb.
Cov yam ntxwv cuam tshuam rau Hygroscopicity ntawm PECVD Graphite Boats
Ob peb yam ua rau hygroscopicity ntawm PECVD graphite nkoj. Thawj qhov yog qhov porosity ntawm cov khoom siv graphite. Graphite tej nkoj nquam nrog porosity ntau dua muaj qhov loj dua qhov chaw raug rau ib puag ncig, uas tso cai rau lawv nqus dej ntau dua. Kev tsim cov txheej txheem ntawm lub nkoj graphite tuaj yeem cuam tshuam nws qhov porosity. Piv txwv li, yog tias cov graphite tsis zoo sintered thaum lub sij hawm tsim khoom, nws yuav muaj porosity ntau dua thiab yog li hygroscopicity ntau dua.
Kev kho saum npoo ntawm lub nkoj graphite kuj ua lub luag haujlwm. Ib qhov dej - kho qhov chaw tuaj yeem tsim cov txheej txheem tiv thaiv uas txo lub nkoj lub peev xwm nqus dej noo. Qee cov neeg muag khoom, suav nrog peb, siv cov txheej txheem tshwj xeeb lossis kev kho mob los txhim kho cov hydrophobicity ntawm graphite nkoj. Cov kev kho mob no tuaj yeem tsim ib qho kev thaiv uas tiv thaiv cov dej molecules los ntawm adhering rau saum npoo ntawm lub nkoj.
Cov xwm txheej ib puag ncig uas cov nkoj graphite khaws cia thiab siv kuj tseem ceeb heev. High humidity ib puag ncig ua rau muaj feem yuav ntawm noo noo nqus. Yog tias cov nkoj tau muab khaws cia rau hauv lub tsev khaws khoom uas muaj qhov cua tsis zoo thiab cov av noo siab, lawv yuav nqus dej ntau dhau sijhawm. Ib yam li ntawd, thaum lub sij hawm PECVD txheej txheem, yog tias lub chamber tsis raug kaw kom zoo lossis yog tias muaj cov xau, cov dej noo los ntawm cov huab cua ib puag ncig tuaj yeem nkag mus thiab nqus los ntawm lub nkoj graphite.
Ntsuas Hygroscopicity ntawm PECVD Graphite Boats
Txhawm rau kom ntseeg tau qhov zoo thiab ua haujlwm ntawm PECVD graphite nkoj, nws yog qhov tseem ceeb los ntsuas lawv cov hygroscopicity. Ib txoj hauv kev yog los ntsuas lub nkoj graphite ua ntej thiab tom qab raug rau qhov chaw tswj cov av noo. Qhov sib txawv ntawm qhov hnyav qhia txog qhov dej noo absorbed. Lwm txoj hauv kev yog siv cov ntsuas dej noo. Cov sensors no tuaj yeem muab tso rau hauv kev sib cuag nrog lub nkoj graphite kom tsis tu ncua saib xyuas cov dej noo.
Los ntawm kev ntsuas qhov hygroscopicity ntawm peb cov nkoj graphite, peb tuaj yeem xyuas kom meej tias lawv ua tau raws li cov qauv nruj nruj uas yuav tsum tau ua los ntawm PV kev lag luam. Qhov no tso cai rau peb muab peb cov neeg siv khoom txhim khu kev qha thiab siab - cov khoom ua tau zoo.
Kev cuam tshuam ntawm Hygroscopicity ntawm PV Cell Production
Lub hygroscopicity ntawm PECVD graphite nkoj tuaj yeem cuam tshuam rau PV cell ntau lawm. Raws li tau hais ua ntej, kev nqus dej tuaj yeem ua rau thermal stress thiab tawg ntawm lub nkoj graphite. Lub nkoj tawg yuav tsis tuav cov silicon wafers ruaj ntseg, uas tuaj yeem ua rau tsis zoo thaum lub sijhawm PECVD txheej txheem. Qhov no misalignment tuaj yeem ua rau tsis sib xws ntawm cov yeeb yaj kiab nyias ntawm cov wafers, txo cov kev ua haujlwm ntawm PV hlwb.
Tsis tas li ntawd, kev sib kis los ntawm cov dej noo - cuam tshuam los ntawm - cov khoom tuaj yeem ua rau muaj kev tsis lees paub ntau dua ntawm PV hlwb. Cov neeg tsim khoom yuav tsum tau siv sijhawm ntau thiab cov peev txheej ntawm kev tswj xyuas kom zoo thiab rov ua haujlwm dua, uas ua rau cov nqi tsim khoom nce ntxiv. Yog li ntawd, txo qis hygroscopicity ntawm PECVD graphite nkoj yog qhov tseem ceeb rau kev txhim kho tag nrho cov txiaj ntsig thiab txiaj ntsig ntawm PV cell ntau lawm.
