Yibuphi ubuchwepheshe obuhamba phambili kuma-photovoltaics eminyakeni yamuva nje?
Ubuchwepheshe Bokusika Izintambo Zedayimane
Inqubo yokusika izinto ze-silicon ezikristalu imelela ingxenye enkulu yezindleko ezingezona eze-silicon embonini ye-PV. Ukusika ucingo lwedayimane kuyindlela entsha yokusika esebenzisa ucingo olumbozwe ngedayimane ukusika ama-wafer e-silicon ngesivinini esikhulu. Uma kuqhathaniswa nokusika udaka lwendabuko, ucingo lwedayimane lusebenza kahle kakhulu. Njengamanje, i-silicon e-monocrystalline isisebenzise ngokugcwele lobu buchwepheshe, futhi ukushintshela kusuka ku-slurry kuya ku-diamond wire ye-multicrystalline silicon kuyashesha.
Amaseli e-PERC (i-Passivated Emitter kanye nobuchwepheshe bamaseli angemuva)
Umehluko oyinhloko wamaseli e-PERC ungqimba lokuhamba phezu kobuso bangemuva, okunciphisa ukuhlangana kwama-electron futhi kuthuthukise ukubonakaliswa kokukhanya. Ekupheleni kuka-2018, umthamo wokukhiqiza amaseli e-PERC emhlabeni wonke wawucishe ube ngu-70GW, kanti umkhiqizo waminyaka yonke udlula u-55GW. Kulindeleke ukuthi ngo-2019, umthamo we-PERC womhlaba wonke uzosondela ku-100GW, ugcine isikhundla sawo esivelele emikhiqizweni yelanga esebenza kahle kakhulu.
Ubuchwepheshe "beDayimane + iSilicon Emnyama"
Ubuchwepheshe be-silicon emnyama buthuthukisa ukumuncwa kokukhanya futhi buthuthukisa ukusebenza kahle kweseli ngokunciphisa ukubonakaliswa kwendawo ngezinqubo ezengeziwe zokwakheka. Ubuchwepheshe be-silicon emnyama eyomile bunikeza izinzuzo zokusebenza kahle eziphezulu kodwa budinga ukutshalwa kwezimali okukhulu. I-silicon emnyama emanzi, enezindleko eziphansi, inikeza ukuthuthukiswa kokusebenza kahle okungu-0.3%-0.5% futhi ithola ukudonswa.
Ubuchwepheshe Beseli Yesibili
Amaseli amabili amelela intuthuko enkulu eminyakeni yamuva nje. Lawa maseli amunca ukukhanya okuvela ezinhlangothini zombili, akhulisa ukukhiqizwa kwamandla ngo-10%-25% kuye ngezimo zemvelo. Ukukhiqizwa kwamaseli amabili anombala owodwa we-N kuye kwanda eminyakeni yamuva nje.
Ubuchwepheshe be-MBB (Multi-Busbar)
Lobu buchwepheshe busebenzisa ama-busbar angu-12, buthuthukisa ukuqoqwa kwamanje, bunciphisa ukulahlekelwa kwangaphakathi, futhi bunciphisa ukufiphaza, okwandisa amandla emojuli okungenani ngo-5W. Buphinde bunciphise amathuba okuqhekeka okuncane futhi buthuthukise ukusebenza ngisho nalapho kwenzeka umonakalo omncane.
Ubuchwepheshe Beseli Elihlanganisiwe
Amamojula eseli ahlanganisiwe asebenzisa amaseli asikiwe ahlelwe ndawonye ngokuqinile, okuvumela amaseli angu-13% engeziwe endaweni efanayo. Lo mklamo uqeda isidingo samaribhoni okunamathisela, unciphisa ukulahlekelwa ukumelana futhi ukhuphula kakhulu amandla okukhipha.
Ubuchwepheshe Beseli Elinqunyiwe Kancane
Amaseli anqunyiwe uhhafu anciphisa ukulahlekelwa kwamandla kagesi futhi athuthukise ukukhishwa kwamandla cishe ngo-10W uma kuqhathaniswa namamojula eseli eligcwele. Ngaphezu kwalokho, amamojula anqunyiwe uhhafu asebenza kahle, kanti amazinga okushisa e-hotspot angaphansi kuka-25°C kunalawo eseli eligcwele.
