Isikhephe se-graphiteyinxalenye ephambili kunye nokusebenza okugqwesileyo kwibala le-photovoltaic. Njengomathiriyeli we-semiconductor, izikhephe ze-graphite wafer azinayo nje ukumelana nokugqwala kunye nokumelana nobushushu obuphezulu, kodwa zinokuhlangabezana neemfuno zezixhobo ze-photovoltaic zokukhula kwekristale ephezulu. Eli nqaku liza kuxubusha ukusetyenziswa kweizikhephe zegraphitekwintsimi ye-photovoltaic kunye nokusebenza kwabo okuhle kakhulu.
Intsimi ye-photovoltaic yintsimi ebalulekileyo esebenzisa amandla elanga ukuguqula umbane ohlaziyiweyo. Kwinkqubo yokwenziwa kwezixhobo ze-photovoltaic, iinqanawa ze-graphite wafer zidlala indima ebalulekileyo. Izikhephe ezisicaba zegraphite zingasetyenziswa kumanyathelo onyango lobushushu obuphezulu ngexesha lokukhula kweeseli zelanga. Ngexesha la manyathelo, iisikhephe se-graphitekufuneka imelane neemeko ezigqithisileyo kwiindawo ezinobushushu obuphezulu ngelixa igcina uzinzo kunye nokuqina.
Ekuqaleni,izikhephe zegraphitebabe nokuxhathisa umhlwa okugqwesileyo. Ngexesha lenkqubo yokwenziwa kwesixhobo se-photovoltaic, iikhemikhali ezahlukeneyo kunye nezisombululo zinokudibana nesikhephe se-wafer. Isikhephe se-graphite wafer sinokuxhathisa ukhukuliseko lweegesi ezidliwayo kunye nemithombo yeendaba elulwelo, ngaloo ndlela ikhusela inkqubo yokukhula kweeseli zelanga ekuphazamisekeni. Oku kuxhathisa umhlwa kwenza ukuba ii-wafers zegraphite zilungele ukusetyenziswa kwiifotovoltaics.
Okwesibini, iisikhephe se-graphiteinokumelana nobushushu obuphezulu. Unyango lobushushu obuphezulu linye lamanyathelo aphambili kwinkqubo yokukhula kweeseli zelanga. I-graphite wafer boat inokugcina uzinzo kwisakhiwo phantsi kweemeko eziphezulu zokushisa ngaphandle kokuguqulwa okanye ukuqhekeka. Oku kubalulekile ukuqinisekisa umgangatho wokukhula kunye nokusebenza kweeseli zelanga. Ukumelana nobushushu obuphezulu be-graphite wafer boat ivumela ukuba imelane namaqondo obushushu angaphezulu ukuya kuma-2,000 degrees Celsius, ihlangabezana neemfuno zenkqubo yokuvelisa izixhobo ze-photovoltaic.
Ukongeza, isikhephe se-wafer segraphite sikwanazo iimpawu ezilungileyo zokuqhuba i-thermal. Ngexesha lokwenziwa kwezixhobo ze-photovoltaic, ukufana kwonyango lwe-thermal kubalulekile ekukhuleni kwekristale. Isikhephe se-graphite wafer sinokukhawuleza ukuhambisa ubushushu kumphezulu kwaye sinikeze indawo efanayo yonyango lokushisa, ngaloo ndlela iqinisekisa ukuhambelana kunye nomgangatho wokukhula kwekristale. I-conductivity yayo egqwesileyo ye-thermal inika inkxaso yokuvelisa ngokufanelekileyo kwintsimi ye-photovoltaic.
Isishwankathelo, iinqanawa ze-graphite wafer zibonise ukusebenza kakuhle kwibala le-photovoltaic. Ukumelana nokugqwala kunye nokumelana nobushushu obuphezulu kwenza iinqanawa ze-graphite wafer zilungele inkqubo yokwenza izixhobo ze-photovoltaic. Ngokubonelela ngeendawo ezizinzileyo zobushushu obuphezulu kunye neempawu ezintle ze-thermal conductivity, iinqanawa ze-graphite wafer zenze igalelo elibalulekileyo ekukhuleni kwekristale ephezulu kunye nokuveliswa ngokufanelekileyo kwintsimi ye-photovoltaic. Kwixesha elizayo lophuhliso lweteknoloji ye-photovoltaic, ii-graphite wafers ziya kuqhubeka zidlala indima ebalulekileyo kwaye zikhuthaze ukukhuthazwa kunye nokusetyenziswa kwamandla avuselelekayo.
