Ngenkqubela phambili yetekhnoloji kunye nokuncipha kwamaxabiso emveliso, isikali sentengiso ye-photovoltaic yehlabathi siya kuqhubeka sikhula ngokukhawuleza, kwaye umyinge weemveliso zohlobo lwe-n kumacandelo ahlukeneyo nawo ayanda ngokuqhubekayo. Amaziko amaninzi aqikelela ukuba ngo-2024, umthamo osanda kufakwa wokuvelisa umbane we-photovoltaic wehlabathi kulindeleke ukuba udlule i-500GW (DC), kwaye inxalenye ye-n-type components yebhetri iya kuqhubeka ikhula kwikota nganye, kunye nesabelo esilindelekileyo ngaphezu kwe-85% ukuphela konyaka.
Kutheni le nto iimveliso zohlobo lwe-n zinokugqibezela ukuphindaphindwa kwetekhnoloji ngokukhawuleza okungaka? Abahlalutyi be-SBI Consultancy babonise ukuba, kwelinye icala, imithombo yomhlaba iya inqabile, ifuna ukuveliswa kombane ococekileyo kwiindawo ezilinganiselwe; kwelinye icala, ngelixa amandla ebhetri yohlobo lwe-n ekhula ngokukhawuleza, umahluko wexabiso kunye neemveliso zohlobo lwe-p ziya zicutheka kancinci. Ngokombono wamaxabiso eebhidi ezivela kumashishini amaninzi aphakathi, umahluko wexabiso phakathi kwamacandelo e-np yenkampani enye kuphela yi-3-5 yeesenti / W, ebonisa indleko-ukusebenza.
Iingcali zetekhnoloji zikholelwa ukuba ukwehla okuqhubekayo kotyalo-mali lwezixhobo, ukuphucuka okuthe gqolo ekusebenzeni kwemveliso, kunye nokubonelela ngemarike okwaneleyo kuthetha ukuba ixabiso leemveliso zohlobo lwe-n liya kuqhubeka nokuhla, kwaye kusekho indlela ende ekufuneka ihambe ekunciphiseni iindleko kunye nokwandisa ukusebenza kakuhle. . Ngelo xesha, bagxininisa ukuba iteknoloji yeZero Busbar (0BB), njengendlela echanekileyo yokunciphisa iindleko kunye nokwandisa ukusebenza kakuhle, iya kudlala indima ebalulekileyo kwimarike ye-photovoltaic ezayo.
Ukujonga kwimbali yeenguqu kwiigridi zeeseli, iiseli ze-photovoltaic zokuqala zine-1-2 yegridi eziphambili kuphela. Emva koko, imigca yegridi emine ephambili kunye nemigca emihlanu ephambili ngokuthe ngcembe yakhokelela kwindlela yoshishino. Ukususela kwisiqingatha sesibini sika-2017, ubuchwepheshe be-Multi Busbar (MBB) buqale ukusetyenziswa, kwaye kamva buphuhliswe kwi-Super Multi Busbar (SMBB). Ngokuqulunqwa kwemigca yegridi eyi-16, indlela yokuhanjiswa kwangoku kwiigridi eziphambili iyancitshiswa, inyusa amandla aphumayo ewonke amacandelo, ukunciphisa ubushushu bokusebenza, kwaye kubangele ukuveliswa kombane okuphezulu.
Njengoko iiprojekthi ezininzi ziqala ukusebenzisa amacandelo ohlobo lwe-n, ukwenzela ukunciphisa ukusetyenziswa kwesilivere, ukunciphisa ukuxhomekeka kwiintsimbi ezixabisekileyo, kunye neendleko eziphantsi zokuvelisa, ezinye iinkampani zecandelo lebhetri ziye zaqala ukuhlola enye indlela - iteknoloji yeZero Busbar (0BB). Kuxelwa ukuba le teknoloji inokunciphisa ukusetyenziswa kwesilivere ngaphezu kwe-10% kwaye yandise amandla ecandelo elinye ngaphezu kwe-5W ngokunciphisa i-shading yangaphambili, elingana nokunyusa inqanaba elinye.
Utshintsho kwithekhnoloji luhlala luhamba kunye nokuphuculwa kweenkqubo kunye nezixhobo. Phakathi kwabo, i-stringer njengesixhobo esisisiseko sokwenziwa kwecandelo inxulumene ngokusondeleyo nophuhliso lwetekhnoloji yegridi. Iingcali zeTekhnoloji zibonise ukuba umsebenzi ophambili we-stringer kukudibanisa i-ribhoni kwiseli ngokufudumeza okuphezulu kobushushu ukwenza intambo, ephethe i-mission ephindwe kabini "yokudibanisa" kunye "noxhumano lwechungechunge", kunye nomgangatho we-welding kunye nokuthembeka ngokuthe ngqo. kuchaphazela isivuno seworkshop kunye nezalathi zamandla emveliso. Nangona kunjalo, ngokunyuka kwetekhnoloji ye-Zero Busbar, iinkqubo zemveli zokutshisa ubushushu obuphezulu ziye zanda zingonelanga kwaye zifuna ukutshintshwa ngokukhawuleza.
Kukulo mongo ukuba i-Little Cow IFC Direct Film Covering iteknoloji ivela. Kuyaqondwa ukuba i-Zero Busbar ixhotyiswe nge-Little Cow IFC Direct Film Covering technology, etshintsha inkqubo ye-welding ye-string yesiqhelo, yenza lula inkqubo ye-cell stringing, kwaye yenza umgca wemveliso uthembeke kwaye ulawuleke.
Okokuqala, le teknoloji ayisebenzisi i-solder flux okanye i-adhesive kwimveliso, ebangela ukuba kungabikho ukungcola kunye nesivuno esiphezulu kwinkqubo. Kwakhona kunqanda ixesha lokunciphisa izixhobo ezibangelwa kukugcinwa kwe-solder flux okanye i-adhesive, ngaloo ndlela iqinisekisa ixesha eliphezulu.
Okwesibini, itekhnoloji ye-IFC ihambisa inkqubo yoqhagamshelo lwe-metalization ukuya kwinqanaba le-laminating, ifezekisa i-welding ngaxeshanye yecandelo lonke. Olu phuculo lukhokelela ekufanisweni kobushushu obungcono be-welding, kunciphisa amazinga e-void, kunye nokuphucula umgangatho we-welding. Nangona iwindow yohlengahlengiso lobushushu yelaminatha imxinwa kweli nqanaba, umphumo welding inokuqinisekiswa ngokulungisa izinto zefilimu ukuze zihambelane nobushushu obufunekayo.
Okwesithathu, njengoko imfuno yentengiso yezixhobo zamandla aphezulu ikhula kwaye umyinge wamaxabiso eeseli uhla kwiindleko zecandelo, ukucutha isithuba phakathi kweeseli, okanye nokusebenzisa isithuba esibi, iba “ngumkhwa.” Ngenxa yoko, amacandelo obungakanani obufanayo anokufikelela kwimveliso ephezulu, ebaluleke kakhulu ekunciphiseni iindleko zecandelo le-non-silicon kunye nokugcina iindleko ze-BOS zenkqubo. Kuxelwa ukuba iteknoloji ye-IFC isebenzisa uxhulumaniso oluguquguqukayo, kwaye iiseli ziyakwazi ukupakishwa kwifilimu, ukunciphisa ngokufanelekileyo i-intercell spacing kunye nokuphumeza iintanda ezifihliweyo phantsi kwesithuba esincinci okanye esibi. Ukongezelela, i-ribbon ye-welding ayifuni ukuba ihlanjululwe ngexesha lenkqubo yokuvelisa, ukunciphisa umngcipheko wokuqhekeka kweeseli ngexesha le-lamination, ukuphucula ngakumbi isivuno sokuvelisa kunye nokuthembeka kwecandelo.
Okwesine, itekhnoloji ye-IFC isebenzisa iribhoni yobushushu obuphantsi, inciphisa ubushushu bonxibelelwano bube ngaphantsi kwe-150.°C. Olu lutsha lunciphisa kakhulu umonakalo woxinzelelo lwe-thermal kwiiseli, lunciphisa ngokufanelekileyo umngcipheko weentanda ezifihliweyo kunye nokuqhekeka kwebhasi emva kokunciphisa iseli, okwenza kube nobubele kwiiseli ezincinci.
Ekugqibeleni, ekubeni iiseli ze-0BB zingenayo i-gridlines eziphambili, ukuchaneka kokubeka i-ribbon ye-welding iphantsi, okwenza i-component yokuvelisa ilula kwaye isebenze ngakumbi, kunye nokuphucula isivuno kwinqanaba elithile. Ngapha koko, emva kokususa imigca yegridi ephambili, amacandelo ngokwawo athandeka ngakumbi kwaye afumene ukuqondwa ngokubanzi kubathengi baseYurophu nase-United States.
Kuyafaneleka ukukhankanya ukuba i-Little Cow IFC Direct Film Covering iteknoloji isombulula ngokugqibeleleyo ingxaki yokulwa emva kwe-welding XBC cells. Kuba iiseli ze-XBC zinemigca yegridi kuphela kwicala elinye, ukuwelda kwentambo eqhelekileyo yobushushu obuphezulu kunokubangela ukulwa kakhulu kweeseli emva kwe-welding. Nangona kunjalo, i-IFC isebenzisa itekhnoloji yokugubungela ifilimu ephantsi yobushushu ukunciphisa uxinzelelo lwe-thermal, okukhokelela kwimitya yeseli ecaba kunye nengafakwanga emva kokugqunywa kwefilimu, iphucula kakhulu umgangatho wemveliso kunye nokuthembeka.
Kuyaqondwa ukuba okwangoku, iinkampani ezininzi ze-HJT kunye ne-XBC zisebenzisa itekhnoloji ye-0BB kumacandelo abo, kwaye iinkampani ezininzi eziphambili ze-TOPCon nazo zibonakalise umdla kobu buchwepheshe. Kulindeleke ukuba kwisiqingatha sesibini se-2024, iimveliso ezininzi ze-0BB ziya kungena kwiimarike, zifake ubutsha obutsha kuphuhliso oluphilileyo noluzinzileyo lwemboni ye-photovoltaic.
