Ziziphi iiteknoloji ezithandwayo kwi-photovoltaics kwiminyaka yakutshanje?
Itekhnoloji yokusika iingcingo zedayimani
Inkqubo yokusika izinto ze-silicon ezikristale imele inxalenye ebalulekileyo yeendleko ezingezizo ze-silicon kwishishini le-PV. Ukusika ucingo lwedayimani yindlela entsha yokusika esebenzisa ucingo olugqunywe yidayimani ukusika ii-wafer ze-silicon ngesantya esiphezulu. Xa kuthelekiswa nokusika kwe-slurry yendabuko, ucingo lwedayimani lubiza kakhulu. Okwangoku, i-silicon ye-monocrystalline isebenzise ngokupheleleyo obu buchwephesha, kwaye utshintsho oluvela kwi-slurry ukuya kwi-diamond wire kwi-multicrystalline silicon lukhawuleza.
Iiseli zePERC (i-Passivated Emitter kunye neTekhnoloji yeeSeli ezingasemva)
Umahluko ophambili kwiiseli zePERC ngumaleko wokudlulela kumphezulu ongasemva, onciphisa ukuphinda kuhlanganiswe kwee-electron kwaye uphucule ukukhanya. Ekupheleni kuka-2018, amandla okuvelisa iiseli zePERC zehlabathi lonke ayemalunga ne-70GW, kunye nemveliso yonyaka edlula i-55GW. Kuqikelelwa ukuba ngo-2019, amandla ePERC yehlabathi jikelele aya kufikelela kwi-100GW, igcine indawo yayo ephambili kwiimveliso zelanga ezisebenzayo kakhulu.
Itekhnoloji "yeDayimane yocingo + iSilicon emnyama"
Itekhnoloji ye-silicon emnyama iphucula ukufunxwa kokukhanya kwaye iphucula ukusebenza kakuhle kweeseli ngokunciphisa ukubonakaliswa komphezulu ngeenkqubo ezongezelelweyo zokuthungwa. Itekhnoloji ye-silicon emnyama eyomileyo inika inzuzo ephezulu yokusebenza kodwa ifuna utyalo-mali olukhulu. I-silicon emnyama emanzi, eneendleko eziphantsi, inika ukonyuka kokusebenza kakuhle kwe-0.3%-0.5% kwaye iyanda ukutsala.
Ubuchwepheshe beeSeli ezimbini
Iiseli zeBifacial zimele impumelelo enkulu kwiminyaka yakutshanje. Ezi seli zifunxa ukukhanya kumacala omabini, zinyusa isivuno samandla nge-10%-25% kuxhomekeke kwiimeko zendalo. Imveliso yeeseli ze-N-type monocrystalline bifacial ibisanda kwiminyaka yakutshanje.
Ubuchwepheshe be-MBB (Multi-Busbar)
Le teknoloji isebenzisa iibhasi ezili-12, iphucula ukuqokelelwa kwangoku, inciphisa ilahleko zangaphakathi, kwaye inciphisa umthunzi, nto leyo enyusa amandla emodyuli ubuncinane nge-5W. Ikwanciphisa amathuba okuba kubekho ii-microcracks kwaye iphucula ukusebenza nokuba kukho umonakalo omncinci.
Ubuchwepheshe beeSeli eziXutyweyo
Iimodyuli zeeseli ezixutyiweyo zisebenzisa iiseli ezisikiweyo ezihlanganiswe ngokuqinileyo, zivumela iiseli ezingaphezulu ezili-13% kwindawo enye. Olu yilo lususa isidingo seeribhoni zokutshiza, lunciphisa ilahleko zokumelana kwaye lunyusa kakhulu amandla okukhupha.
Ubuchwepheshe beeSeli eziSikiweyo iHalf-Cut
Iiseli ezisikiweyo isiqingatha zinciphisa ilahleko yamandla kwaye ziphucula amandla aphumayo malunga ne-10W xa kuthelekiswa neemodyuli ze-full-cell. Ukongeza, iimodyuli ezisikiweyo isiqingatha zisebenza kakuhle, kwaye amaqondo obushushu e-hotspot angaphantsi kwama-25°C kunalawo eeyunithi ze-full-cell.
