Khawuthelekelele ihlabathi apho iiphaneli zelanga zidibana khona ngokungenamthungo eluphahleni, zibamba yonke imisebe yelanga ngempumelelo engakaze ibonwe. Eli asilophupha likude kodwa yinyani ekhulayo ngenxa yeeseli zelanga zeBC. Ingcaciso emfutshane yeBack Qhagamshelana neeseli zelanga, iteknoloji yeBC iguqula ishishini lelanga ngoyilo lwayo olutsha kunye nokusebenza okugqwesileyo. Makhe sihlolisise imimangaliso yeeseli zelanga zeBC kunye nekamva lazo elithembisayo.
Uyilo Olunobuchule lwee-BC Solar Cells
Iiseli zelanga ze-BC, okanye iiseli zelanga zeBack Contact, zingumzekelo woyilo olutsha kwindawo yamandla elanga. Khawucinge ngoku: zonke iindawo zokunxibelelana zesinyithi kunye neendawo zokuhlangana ezihlala zixinene nomphezulu ongaphambili weseli yelanga zishukunyiswa ngasemva. Olu hlengahlengiso lubalaseleyo lususa imigca yegridi engathandekiyo ethintela ukukhanya kwelanga, ivumela iseli ukuba ifunxe yonke isuntswana yokukhanya. Isiphumo? Iseli yelanga ethambileyo nesebenzayo ebamba ukukhanya kwelanga okungakumbi kwaye iyiguqule ibe ngamandla ngempumelelo.
Itekhnoloji ye-BC ayilonyathelo elikhethekileyo kodwa linyathelo lokuguquka elisekelwe kubuchwepheshe obukhoyo. Ngokuboleka iimpawu ezilungileyo kwiindlela zangaphambili kwaye uzidibanise kwimo entsha, ephuculweyo, iiseli zelanga ze-BC zifumana uphuculo olumangalisayo lokusebenza kakuhle.
Ukusebenza kakuhle okuKhanya ngakumbi
Ukusebenza kakuhle yeyona nto ibalulekileyo kwitekhnoloji yelanga, kwaye iiseli zelanga zeBC zibeka imilinganiselo emitsha. Iiphaneli zePerc zendabuko (Passivated Emitter kunye neRear Cell) ziyakwazi ukuguqula malunga ne-20-22% yokukhanya kwelanga ibe ngumbane, ngelixa iiphaneli zeTopcon (Tunnel Oxide Passivated Contact) zityhala elo nani ukuya kuthi ga kwi-23%. Nangona kunjalo, iiseli zelanga zeBC ziyisa kwinqanaba elilandelayo ngokuphumelela kwemveliso malunga ne-24.5% kunye nokusebenza kovavanyo okukhulayo phakathi kwe-27-29%. Olu phuculo lwe-2-3% kwiiseli zelanga ze-N-TOPCon lutshintsho olukhulu, olunika inqanaba elikhulu kwitekhnoloji yelanga.
I-Symphony of Technologies
Okwenza iteknoloji yeBC ibe nomtsalane ngokwenene kukuba iyasebenza ngeendlela ezahlukeneyo. Iiseli zelanga zeBC zinokuhambelana nezinye iiteknoloji eziphambili ezifana nePerc, TOPCon, kunye neHJT (Heterojunction Technology) ukwenza iiseli ezixutyiweyo. Khawuthelekelele amathuba anokwenzeka: iHPBC (Heterojunction with Back Contact), iTBC (TOPCon with Back Contact), kunye neHBC (Heterojunction Back Contact). Ezi hybrids zifana neenkanyezi zehlabathi lelanga, zidibanisa amandla eetekhnoloji ezininzi ukuze zinyuse ukusebenza kakuhle ziye kwinqanaba elitsha.
Iimpawu ezikhethekileyo zee-BC Solar Cells
1. Ukukhanya kwelanga okungaphazanyiswanga
Njengoko imigca yegridi yesinyithi ishukunyiselwa ngasemva, ii-BC solar cells zibonelela ngomphezulu ococekileyo, ongaqhekekanga obamba ukukhanya kwelanga okungakumbi kwaye uwuguqule ube ngamandla ngokusebenza kakuhle.
Ukuphucula ukusebenza kakuhle kokuguqula
Utshintsho loyilo lukhokelela kumazinga aphezulu okuguqulwa, okwenza ii-BC solar cells zibe namandla kummandla wamandla elanga.
2. Ubuhle Bobuhle
Ukungabikho kwemigca yegridi ejonge ngaphambili kunika iiphaneli zelanga zeBC inkangeleko entle nefanayo, nto leyo eyenza zibe lukhetho olunomtsalane kwiindawo zokuhlala nakwiindawo zorhwebo.
Ukuhlanganiswa kweHybrid
Ukukwazi ukudibanisa iteknoloji ye-BC nezinye iiteknoloji zelanga eziphambili kubangela iiseli ezixutyiweyo eziphucula ukusebenza kakuhle nokusebenza.
3. Ubukho beMarike kunye namathemba aqaqambileyo
Okwangoku, ii-BC solar cells zifana namatye anqabileyo afihliweyo kwimarike enkulu yelanga, ziphethe isabelo se-0.2% kuphela xa kuthelekiswa ne-TOPCon ephetheyo engama-70%. Kodwa ababukeli beli shishini abanjengoLONGI Green Energy baqikelela ukuba kuza kubakho utshintsho olukhulu. I-LONGI iqikelela ukuba kwiminyaka emi-5-6 ezayo, ii-BC solar cells ziza kuphakama zibe zibalaseleyo, nto leyo enokuthi isuse iTopcon njengobuchwepheshe belanga obuphambili.
4. Ikamva Liqaqambile ngee-BC Solar Cells
Iiseli zelanga ze-BC azikho nje uphuculo oluqhubekayo; zimele ukutsiba okunesibindi phambili. Ngokunciphisa ukulahleka komthunzi kunye nokuphucula ukusebenza kakuhle kokuguqulwa, iteknoloji ye-BC ithembisa ukuyila ngokutsha imeko yamandla elanga. Nangona iiseli ze-BC okwangoku zithatha indawo encinci kwimarike, ukusebenza kwazo okuphezulu kunye nokukhanga kobuhle kuzibeka njengabakhuphisana nabo abanamandla kwiiteknoloji ezisele zikho njengePerc kunye neTopcon.
Amandla okwenyani eeseli ze-BC axhomekeke ekuziqhelaniseni kwazo. Ngokudibana nezinye iiteknoloji, iiseli ze-BC zinokuguquka zibe zii-powerhouses ezixutyiweyo, zityhale imida yoko iiseli zelanga zinokukufezekisa. Njengoko ihlabathi litshintshela kumandla avuselelekayo, iiseli zelanga ze-BC zimi zilungele ukukhokela utshaja, ziguqula uphahla zibe ziijenereyitha zamandla ezithambileyo nezisebenzayo.
Ngoko ke, kwixesha elizayo xa ujonga elangeni, khawucinge ngomlingo ongabonakaliyo weeseli zelanga ze-BC ezisebenza ngokungakhathali ukuze zisebenzise amandla azo. Kuyo yonke imisebe yokukhanya kwelanga kukho isithembiso sekamva eliqaqambileyo neliluhlaza ngakumbi, kwaye itekhnoloji ye-BC ilapha ukuze yenze eso sithembiso sibe yinyani.
