Zeziphi iimfuno ezintsha ezibekwa lixesha le-N-type cell kwiimveliso ze-quartz

Ukuphuculwa kwetekhnoloji ye-photovoltaic kuqhuba ukukhula okuqhubekayo kwemfuno ye-quartz ecocekileyo kakhulu

Njengoko ishishini le-photovoltaic (PV) lehlabathi liphela likhawulezisa utshintsho lwalo oluya ekusebenzeni kakuhle, iiseli zohlobo lwe-N ziya ziba yimarike ephambili kancinci kancinci. Iindlela zobuchwepheshe bohlobo lwe-N—ezifana ne-TOPCon, i-HJT, kunye ne-BC—ziqhuba igagasi elitsha lokwandiswa kwamandla ngenxa yokusebenza kwazo okuphezulu kokuguqula, amazinga aphantsi okuwohloka, kunye nokusebenza okungcono kokuvelisa umbane. Kwangaxeshanye, iimveliso ze-quartz ezicocekileyo kakhulu—izinto ezibalulekileyo ezisetyenziswayo ekuvelisweni kwe-PV—zijongene nemigangatho ephezulu kunye neemfuno zobugcisa ezingqongqo. Abantu abangaphakathi kushishino baqaphela ukuba ukuphuculwa kwenkqubo yeeseli zohlobo lwe-N akutshintshi nje kuphela indlela yokusebenza kwemveliso kodwa kukwabangele nemingeni emitsha malunga nobunyulu, ukumelana nobushushu, kunye nobomi benkonzo yezinto eziphambili ze-quartz, ezifana neenqanawa ze-quartz, iityhubhu ze-furnace, iityhubhu zokusasazwa, kunye neejari zentsimbi.

Iinkqubo zohlobo lwe-N zifuna ubunyulu obuphezulu kwizixhobo ze-quartz

Amanqanaba aphambili kwimveliso ye-TOPCon kunye ne-HJT—njengokusasazwa kobushushu obuphezulu, i-oxidation, kunye ne-annealing—axhomekeke kakhulu kwiimveliso ze-quartz. Xa kuthelekiswa neeseli zohlobo lwe-P, iiseli zohlobo lwe-N zinovelwano ngakumbi kukungcola kwesinyithi. Izinto ezilandelelanayo ezifana ne-iron (Fe), i-aluminium (Al), i-sodium (Na), kunye ne-potassium (K) zinokuchaphazela umgangatho womphezulu we-silicon wafer kunye nokusebenza kakuhle kokuguqulwa kweeseli.

Ngenxa yoko, iimveliso ze-quartz ezisetyenziswa kwimigca yemveliso yohlobo lwe-N zifuna izinto eziluhlaza ze-quartz ezikumgangatho ophezulu ukuqinisekisa:

• Ubungakanani bokungcola kwesinyithi obuphantsi;
• Ubunyulu obuphezulu beekhemikhali;
• Umngcipheko oncitshisiweyo wokuphelelwa ngamandla (i-crystallization);
• Ukusebenza okuzinzileyo ngakumbi kumaqondo obushushu aphezulu.

Okwangoku, abanye abavelisi beeseli abaphambili baphakamise imigangatho yabo yobumsulwa kwiimveliso ze-quartz ukuya kumanqanaba e-semiconductor ukuze bahlangabezane neemfuno zococeko zemigca yemveliso ephucukileyo.

Iinkqubo zobushushu obuphezulu ziqhuba ukuphuculwa kokumelana nobushushu kweemveliso ze-quartz

Amaqondo obushushu okusasazwa kweeseli ze-TOPCon adla ngokudlula i-800°C, ngelixa amanqanaba athile enkqubo ye-HJT ebeka iimfuno eziphezulu ngakumbi kuzinzo lwezixhobo.

Ukusebenza ixesha elide kubushushu obuphezulu kunokukhokelela kwimiba efana nokuguquguquka, ukuguquguquka kwe-vitrification, ukuhanjiswa kokukhanya okunciphileyo, umonakalo wokutshatyalaliswa kobushushu, kunye nobomi benkonzo obufutshane.

Ngoko ke, isizukulwana esitsha seemveliso ze-quartz sifuna uzinzo oluphezulu lobushushu kunye nokumelana nokutshayiswa kobushushu. Ngokuphucula iinkqubo zokunyibilika, ukulawula umxholo we-hydroxyl, kunye nokuphucula izakhiwo zezinto zangaphakathi, iimveliso ze-quartz zinokufikelela ubomi obude benkonzo kwiindawo ezinobushushu obuphezulu, zincede amashishini e-photovoltaic anciphise iindleko zokugcinwa kwezixhobo kunye nexesha lokungasebenzi.

Iiwafer ezinkulu zikhuthaza uyilo lwesakhiwo kwiinqanawa ze-quartz

Ukwamkelwa ngokubanzi kwee-wafers ze-182mm, 210mm, kunye nezinkulu ngakumbi kuye kwandisa kakhulu ubunzima bokuyilwa kweenqanawa ze-quartz.

Ukutshintshela kwiisayizi ezinkulu ze-wafer kubeka ezi mfuno zilandelayo kwiinqanawa ze-quartz:

• Amandla aphezulu oomatshini;
• Ukuguqulwa okuncinci;
• Ulawulo oluchanekileyo lwesithuba seslothi;
• Uzinzo oluphezulu lokulayisha i-wafer.

Nokuba ukuguquka okuncinci kwinqanawa ye-quartz kunokuchaphazela isithuba se-wafer kunye nokufana kwentsimi yobushushu, ekugqibeleni okukhokelela ekunciphiseni isivuno.

Ngenxa yoko, inani elikhulayo labathengisi bemveliso ye-quartz basebenzisa iindlela zokuchonga ze-CNC ezichanekileyo kunye neenkqubo zokuhlola ezingqongqo ukuqinisekisa ukuba iimveliso zabo ziyahlangabezana neemfuno zemveliso yeeseli zelanga ezinkulu.

Imveliso ezenzekelayo iqhuba isidingo soomatshini abachanekileyo

Izakhiwo zokwenza i-photovoltaic ngoku ziyaguquka zibe yimveliso ekrelekrele kunye nemisebenzi engenabantu.

Ukusasazwa okukhulu kweenkqubo zokulayisha/zokukhulula izinto ngokuzenzekelayo, izixhobo zokuphatha iirobhothi, kunye nezixhobo zokuhlola ngokuzenzekelayo kuthetha ukuba iimveliso ze-quartz akufuneki zibe neempawu ezintle zezinto ezibonakalayo kuphela kodwa zibonise ukuchaneka okuphezulu kunye nokuhambelana.

Iindawo eziphambili ziquka:

• Ulawulo lokunyamezelana kweslot kwiinqanawa ze-quartz;
• Ulawulo lweConcentricity kwiityhubhu zesithando se-quartz;
• Ukuchaneka kobukhulu boqhagamshelo lweflange;
• Ukuqina okuqinileyo kwamalungu adibeneyo.

Ezi zibalo zichaphazela ngokuthe ngqo ukusebenza kakuhle kwezixhobo kunye nokuzinza kwemigca yemveliso ezenzekelayo.

Ukutshintshwa kwelizwe kukhawulezisa amathuba emarike

Kwiminyaka yakutshanje, ukuqhubela phambili okuqhubekayo kubuchwepheshe bezinto ze-quartz ezicocekileyo kakhulu zasekhaya kukhokelele ekwandeni okuqhubekayo kwisabelo semarike seemveliso ze-quartz eziveliswa ekhaya kwicandelo le-photovoltaic. Ngokukodwa ngenxa yokwanda okukhulu komthamo wetekhnoloji ye-TOPCon, imfuno yezikhephe ze-quartz ezikumgangatho ophezulu, iityhubhu zesithando somlilo, kunye nezinto ezinxulumene nazo ziye zanda, zidala amathuba amatsha okukhula kwamashishini e-quartz asekhaya. Uqikelelo lweshishini lubonisa ukuba amandla okuvelisa iiseli zohlobo lwe-N aya kuqhubeka ekhula kwiminyaka ezayo, okwenza iimveliso ze-quartz ezicocekileyo kakhulu, ezihlala ixesha elide, kunye nezichanekileyo kakhulu zibe zizinto ezibalulekileyo ezixhasayo kwikhonkco lokubonelela nge-photovoltaic. Amashishini e-quartz anakho ukuphucula ngokupheleleyo izinto zawo ezikrwada, iinkqubo, amandla oomatshini, kunye nemigangatho yokuhlola akwindawo efanelekileyo yokufumana inzuzo yokukhuphisana kwisigaba esilandelayo sophuhliso lweshishini.

Isiphelo

Ixesha leeseli zohlobo lwe-N alimeli nje kuphela ukuphuculwa kwetekhnoloji ye-photovoltaic kodwa likwaluvavanyo olupheleleyo lwezinto ezixhasa uthotho lokubonelela ngeshishini. Njengezinto ezibalulekileyo ezisetyenziswayo kwiinkqubo zokusasazeka kobushushu obuphezulu kunye nonyango lobushushu, iimveliso ze-quartz ziyaguquka ukusuka "kwizinto ezincedisayo" ukuya "kwizinto ezibalulekileyo ekusebenzeni." Ukuqhubekela phambili, ubunyulu obuphezulu, ukuchaneka, kunye nobomi benkonzo ende kuya kuba zizikhokelo eziphambili zophuhliso lweemveliso ze-quartz, ziqhubela lonke ishishini le-quartz kwinqanaba eliphezulu lobuchwephesha.
