Isikebhe esicwecwana se-graphiteiyisici esiyinhloko esisebenza kahle kakhulu emkhakheni we-photovoltaic. Njengempahla ye-semiconductor, izikebhe ze-graphite wafer azigcini nje ngokumelana nokugqwala nokumelana nokushisa okuphezulu, kodwa futhi zingahlangabezana nezidingo zemishini ye-photovoltaic yokukhula kwe-crystal ephezulu. Lesi sihloko sizoxoxa ngokusetshenziswa kweama-graphite wafer izikebheemkhakheni we-photovoltaic nokusebenza kwawo okuhle kakhulu.
Inkambu ye-photovoltaic iyinkambu ebalulekile esebenzisa amandla elanga ukuguqula ugesi ovuselelekayo. Enqubweni yokukhiqiza imishini ye-photovoltaic, izikebhe ze-graphite wafer zidlala indima ebalulekile. Izikebhe ze-wafer ze-graphite zingasetshenziswa ezinyathelweni zokwelashwa kokushisa okuphezulu ngesikhathi sokukhula kwamaseli elanga. Phakathi nalezi zinyathelo, i-isikebhe esicwecwana se-graphiteidinga ukumelana nezimo ezimbi kakhulu ezindaweni ezinezinga eliphezulu lokushisa ngenkathi igcina ukuzinza nokuqina.
Okokuqala,ama-graphite wafer izikebheube nokumelana nokugqwala okuhle kakhulu. Phakathi nenqubo yokukhiqiza idivayisi ye-photovoltaic, amakhemikhali ahlukahlukene kanye nezixazululo zingase zihlangane nesikebhe se-wafer. Isikebhe esilucwecwana se-graphite singamelana nokuguguleka kwamagesi agqwalayo kanye nemidiya ewuketshezi, ngaleyo ndlela ivikele inqubo yokukhula yamaseli elanga ekuphazamisekeni. Lokhu kumelana nokugqwala kwenza ama-wafers e-graphite alungele ukusetshenziswa kuma-photovoltaics.
Okwesibili, iisikebhe esicwecwana se-graphiteinokumelana okuhle kakhulu nokushisa okuphezulu. Ukwelashwa kokushisa okusezingeni eliphezulu kungenye yezinyathelo ezibalulekile enqubweni yokukhula kwamaseli elanga. Isikebhe esilucwecwana se-graphite singagcina ukuzinza kwesakhiwo ngaphansi kwezimo zokushisa okuphezulu ngaphandle kokuguqulwa noma ukuqhekeka. Lokhu kubalulekile ukuqinisekisa izinga lokukhula nokusebenza kwamaseli elanga. Ukumelana nezinga lokushisa eliphezulu kwesikebhe se-graphite wafer kusivumela ukuthi simelane namazinga okushisa afinyelela ku-2,000 degrees Celsius, sihlangabezana nezidingo zenqubo yokukhiqiza imishini ye-photovoltaic.
Ngaphezu kwalokho, isikebhe se-wafer se-graphite sibuye sibe nezakhiwo ezinhle zokushisa ezishisayo. Ngesikhathi sokwenziwa kwemishini ye-photovoltaic, ukufana kokwelashwa okushisayo kubalulekile ekukhuleni kwekristalu. Isikebhe esicwecwana se-graphite singasheshisa ukushisa phezulu futhi sinikeze indawo yokwelashwa yokushisa efanayo, ngaleyo ndlela siqinisekise ukuhambisana nekhwalithi yokukhula kwekristalu. I-conductivity yayo enhle kakhulu yokushisa inikeza ukusekelwa kokukhiqiza okuphumelelayo emkhakheni we-photovoltaic.
Kafushane, izikebhe ze-graphite wafer zibonise ukusebenza okuhle kakhulu emkhakheni we-photovoltaic. Ukumelana nokugqwala kwayo nokumelana nokushisa okuphezulu kwenza izikebhe ze-graphite wafer zilungele inqubo yokukhiqiza imishini ye-photovoltaic. Ngokuhlinzeka ngemvelo ezinzile yokushisa okuphezulu kanye nezakhiwo ezinhle zokushisa ezishisayo, izikebhe ze-graphite wafer zenze iminikelo ebalulekile ekukhuleni kwe-crystal yekhwalithi ephezulu kanye nokukhiqizwa okuphumelelayo emkhakheni we-photovoltaic. Ekuthuthukisweni kwesikhathi esizayo kobuchwepheshe be-photovoltaic, ama-wafers e-graphite azoqhubeka edlala indima ebalulekile futhi akhuthaze ukukhuthazwa nokusetshenziswa kwamandla avuselelekayo.
