UTrina Solar yinkokeli yamanye amazwe kwiimodyuli ze-photovoltaic (PV), izisombululo kunye neenkonzo. Kwiintsuku ezimbalwa ezidlulileyo ibhengeze ukuba iziko eliphambili le-R & D lezenzululwazi kunye netekhnoloji ye-photovoltaic (PVST) iseke irekhodi elitsha ngokusebenza kakuhle Indawo eyi-24,13% iyonke yesilicon ye-monocrystalline, uhlobo N (c-Si) iseli yelanga enendawo enkulu (156 x 156 mm2) yokunxibelelana ngasemva (IBC).
Iphaneli yokuqhekeza irekhodi le-N-uhlobo lwe-monocrystalline yesilicon yolawulo lwelanga yenziwe nge-phosphor-doped Cz enkulu (Czochralski) yesilicon substrate ngenkqubo yemizi-mveliso I-IBC enexabiso eliphantsi, isebenzisa ubuchwephesha obuqhelekileyo kunye neetekhnoloji zokwenza isinyithi ngokupheleleyo kwisikrini esishicilelweyo.
Iphaneli yelanga eyi-156 × 156mm2 iphumelele ngokusebenza kwendawo eyi-24,13% ngokwe imilinganiselo ezizimeleyo yenziwe yiLabhoratri yeTekhnoloji yoKhuseleko loMbane neNdalo eJapan (iJET).
Iseli yelanga ye-IBC inendawo epheleleyo engama-243,3 cm2; loo milinganiselo yenziwe ngaphandle kokuvulwa. Iseli eliphumeleleyo libonisa ezi mpawu zilandelayo: ivolthi yesekethe evulekileyo ye-702,7 mV, a Ukuxinana okwangoku kwesekethe I-Jsc ye-42,1 mA / cm2 kunye nokuzaliswa kwe-FF ye-81,47%.
Impumelelo yeTrina Solar
NgoFebruwari 2014, uTrina Solar kunye neYunivesithi yeSizwe yase-Australia (ANU) ngokudibeneyo babhengeza irekhodi le- I-24,37% yokuvula ukusebenza Kwiseli yelanga ye-IBC, kwinqanaba lelebhu le-4 cm2, elenziwe ngohlobo lwe-N substrate kunye nendlela yendawo edadayo (FZ) kunye nokusebenzisa ukwenziwa kweepateni ngefotolithography.
Ekupheleni konyaka ka-2014, uTrina Solar wabhengeza Ukusebenza kwendawo eyi-22,94% Inguqulelo yezentengiso yeseli enkulu yelanga ye-IBC (156 x 156 mm2, ene-substrate eyi-6-intshi). Ngo-Epreli 2016, uTrina Solar wabhengeza ukudalwa kweendleko eziphantsi, ezomzi mveliso, eziphuculweyo zeseli yelanga ene-23,5% yendawo yonke.
Ingxelo eNtsha yeNgcaciso yeNgingqi I-24,13% yi-0,24% kuphela Ngaphantsi kwerekhodi yendawo encinci yokuvula ukusebenza kwilabhoratri yeeseli, setwa ngokudibeneyo yiNkampani kunye ne-ANU. Indawo esebenzayo iyonke ihlala isezantsi kuneendawo zokuvula, ngenxa yelahleko yokusebenza ngokunxulumene nemiphetho yeseli kunye neendawo zonxibelelwano zombane.
NgokukaGqirha uPierre Verlinder, uSekela Mongameli kunye neNzululwazi eyiNtloko yeTrina Solar: “Siyavuya ukwazisa impumelelo entsha Iqela lethu lophando kwi-SKL PVST. Ngexesha leminyaka edlulileyo, iqela lethu le-R & D likwazile ukuqhubeka nokuphucula ukusebenza kweepaneli zelanga ze-N-type IBC, ukugqitha imida kunye nokwaphula iirekhodi zangaphambili; kunye nokusondela kwintsebenzo yethu eyona ndawo incinci yeseli elebhu eyenziwe ngophatho lwe ANU kwiminyaka emithathu edlulileyo ”.
Iipaneli zesola ze-IBC yenye yeeseli zelanga ngakumbi i-silicon namhlanje, kwaye zilungele ngokukodwa izicelo apho imfuneko yokuxinana ngamandla kubaluleke ngaphezu kwe-LCOE (ixabiso eliqhelekileyo lombane).
Ngokwabaphathi beenkampani: Inkqubo yethu yeseli ihlala ijolise kuphuhliso lweeseli ezinkulu zommandla kunye neenkqubo zeshishini ezinendleko eziphantsi. Namhlanje sonwabile Yazisa ukuba indawo yethu enkulu ye-IBC ifikelele kwinqanaba elifanayo lokusebenza kunendawo encinci yeseli eyenziwe elebhu kwiminyaka emithathu edlulileyo ngenkqubo ye-photolithography.
Kwimveliso ye-photovoltaic ziqhutywa kukutsha, I-Trina Solar ihlala ijolise ekuphuhliseni iimveliso ze-PV kunye neetekhnoloji zokuphucula ukusebenza kweeseli kunye nokunciphisa iindleko zenkqubo. Lakhe eyona njongo iphambili kukuphembelela ukuveliswa kwetekhnoloji, kunye nokudlulisa, ngokukhawuleza okukhulu, iteknoloji ukusuka elabhoratri iye kwimveliso yorhwebo ”.
Olunye uhambelo phambili kumandla elanga
Iiperovskites
Iiseli zelanga zelanga ezisekwe kwilasoni namhlanje zinengxaki ethile: zenziwe ngezinto ezinqabileyo ifunyenwe kwindalo kwifomu emsulwa neyimfuneko yokwenza, zinzima kwaye zinzima, kwaye ukusebenza kwazo kunciphile kwaye kunzima ukukala.
Izinto ezintsha, ezibizwa ngokuba yi-perovskites, zicetyiswa ukusombulula olu thintelo kuba luxhomekeke kwizinto ezininzi kwaye zitshiphu njengoko zinokubanakho ukufezekisa ukusebenza ngokukuko.
Iiperovskites zi Udidi olubanzi lwezixhobo apho iimolekyuli ze-organic ezenziwa ikakhulu ziibhondi zekhabhon kunye nehydrogen enesinyithi, ezinje nge lead, kunye ne halogen, njenge klorine, kwikristale emile okwe-lattice.
Banokufunyanwa nge lula lula, ngexabiso eliphantsi kwaye ngaphandle kokukhutshwa, okukhokelela kwifilimu encinci kwaye elula enokulungiswa kuyo nayiphi na imeko, enokuvumela ukwenziwa kweepaneli zelanga ngendlela elula, efanelekileyo nangendlela iziphumo eziguquguqukayo kwaye kulula ukuyifaka.
Nangona kunjalo, banezithintelo ezibini: eyokuqala kukuba ukubanakho ukuzidibanisa zibe imveliso enkulu akukabikho bungqina; enye, abaqhele ukuyenza yophula ngokukhawuleza okukhulu kwiimeko zokwenyani.
Inki ye-Photovoltaic
Ukusombulula ezi ngxaki ze-perovskites, iqela elivela e-US National Renewable Energy Laboratory lenze indlela entsha yokujongana nayo. Imalunga nokwenza 'inki ye-photovoltaic evumela ukuba babe kwiinkqubo zemveliso ezenzekelayo.
Olu phando luqale nge I-pervoskite elula kakhulu eyenziwe nge-iodine, ilothe kunye ne-methylammonium. Phantsi kweemeko eziqhelekileyo, lo mxube unokwenza ngokulula iikristali, kodwa kungathatha ixesha elide kumaqondo obushushu aphezulu ukuqinisa kamva, okuya kuthi kulibazise kwaye inkqubo yokuvelisa ibize kakhulu. Ke iqela likhangele iimeko ezinokukhawulezisa ukwenziwa kwekristale, ebandakanya ukubuyisela ezinye izinto endaweni yazo, ezinje ngechlorine, kunye Yongeza oko bakubiza ngokuba yi "negative solvent", into eya kusombulula isisombululo ngokukhawuleza.
