UTrina Solar ungumholi wamazwe omhlaba kumamojula we-photovoltaic (PV), izixazululo nezinsizakalo. Ezinsukwini ezimbalwa ezedlule yamemezela ukuthi isikhungo sayo esikhulu se-R & D se-photovoltaic science and technology (PVST) sesisungule irekhodi elisha elinekhono Indawo engu-24,13% ephelele yesilicon ye-monocrystalline, thayipha iseli lelanga u-N (c-Si) elinendawo enkulu (156 x 156 mm2) oxhumana naye ongemuva (IBC).
Iphaneli yokuqopha irekhodi le-N-type monocrystalline silicon solar yenziwa nge-substrate enkulu ye-phosphor-doped Cz (Czochralski) ngenqubo yezimboni amanani aphansi e-IBC, kuqashwa ubuchwepheshe obujwayelekile be-doping kanye ne-metallization esikrinini esiphrintiwe ngokuphelele.
Iphaneli yelanga engu-156 × 156 mm2 ithole ukusebenza kwendawo okuphelele ngama-24,13% ngokusho kwe- ukukala okuzimele okwenziwe yiJapan Electrical and Environmental Safety Technology Laboratory (JET).
Iseli elanga le-IBC linendawo ephelele engu-243,3 cm2; isilinganiso esinjalo senziwa ngaphandle kokuvula imbobo. Iseli eliwinayo linezici ezilandelayo: i-voltage yesifunda evulekile ye-Voc engu-702,7 mV, a ukuminyana kwesifunda okufishane I-Jsc engu-42,1 mA / cm2 kanye nesici sokugcwalisa i-FF esingu-81,47%.
Izimpumelelo zeTrina Solar
NgoFebhuwari 2014, uTrina Solar kanye ne-Australian National University (ANU) ngokuhlanganyela bamemezela irekhodi le- Ukusebenza kokuvula okungu-24,37% esitokisini selanga se-IBC, esikalini selabhorethri esingu-4 cm2, esenziwe ngohlobo N substrate enendawo entantayo yendawo (FZ) nokusebenzisa ukwenziwa kwamaphethini ane-photolithography.
Ngasekupheleni kuka-2014, kumenyezelwe uTrina Solar ukusebenza kahle kwendawo okuphelele kwe-22,94% yenguqulo yezimboni yeseli enkulu yelanga ye-IBC (156 x 156 mm2, ene-substrate engu-6 intshi). Ngo-Ephreli 2016, uTrina Solar wamemezela ukwakhiwa kweseli elisebenza ngamanani aphansi, lezimboni, elithuthukisiwe le-IBC elinendawo ephelele yokusebenza okungu-23,5%.
I-New Total Area Efficiency Record I-24,13% ingu-0,24% kuphela ngokuphelele ngezansi kwerekhodi lokusebenza kahle kokuvuleka kwendawo encane elabhoratri yamaseli, isethwe ngokuhlanganyela yiNkampani kanye ne-ANU. Ukusebenza kahle kwendawo okuphelele kuhlala kuphansi kunokusebenza kahle kokuvula, ngenxa yokulahleka kokusebenza kahle okuhlobene nemiphetho yamaseli nezindawo zokuxhumana zikagesi.
Ngokusho kukaDkt. Pierre Verlinder, iSekela likaMongameli kanye noSosayensi Oyinhloko waseTrina Solar: “Siyajabula ukumemezela impumelelo yakamuva ye ithimba lethu locwaningo eSKL PVST. Phakathi neminyaka edlule, ithimba lethu le-R & D likwazile ukuqhubeka nokuthuthukisa ukusebenza kahle kwamapaneli ethu elanga we-N-type IBC, edlula imikhawulo futhi ephula amarekhodi angaphambilini; nokuphatha ukusondela ekusebenzeni kwe- iseli lendawo elingcono kakhulu elabhoratri elakhiwa ngokubambisana ne-ANU eminyakeni emithathu eyedlule ”.
“Ama-solar panel e-IBC angenye yamaseli elanga we i-silicon esebenza kahle kakhulu namuhla, futhi zilungele ikakhulukazi izicelo lapho imfuneko yamandla aphezulu ibaluleke ngaphezu kwe-LCOE (izindleko ezijwayelekile zikagesi).
Ngokusho kwabaphathi benkampani: Uhlelo lwethu lweseli luhlale lugxile ekwakhiweni kwamaseli endawo enkulu nezinqubo zezimboni ezingabizi kakhulu. Namuhla siyajabula memezela ukuthi indawo yethu enkulu ye-IBC cell ifinyelele cishe ezingeni elifanayo lokusebenza kuneseli lendawo elincane elenziwe elabhoratri eminyakeni emithathu eyedlule ngenqubo ye-photolithography.
Emkhakheni we-photovoltaic iqhutshwa yimisha emisha, ITrina Solar ihlale igxile ekwakhiweni kwemikhiqizo ye-PV enqenqemeni nobuchwepheshe ngokusebenza kahle kwamaseli nezindleko zohlelo ezincishisiwe. Kwakhe Inhloso enkulu kungukuthonya ubuchwepheshe obusha, futhi kudluliswe, ngokushesha okukhulu, ubuchwepheshe busuka elabhoratri buye ekukhiqizweni kwezebhizinisi ”.
Okunye ukuthuthuka kwamandla elanga
Ama-Perovskites
Amaseli elanga anamuhla asuselwa ku-silicon ahlupheka ngokulinganiselwa okuthile: enziwe ngento engavamile itholakala endalweni ngendlela emsulwa futhi edingekayo ukuyenza, zinzima futhi zinzima, futhi ukusebenza kwazo ngokulinganiselwe kunqunyelwe futhi kunzima ukukala.
Izinto ezintsha, ezibizwa ngama-perovskites, kuhlongozwa ukuxazululwa le mikhawulo ngoba incike ezintweni eziningi futhi ezishibhile njengoba zinamandla okufeza ukusebenza kahle okukhulu.
AmaPerovskites ayi isigaba esibanzi sezinto zokwakha lapho ama-molecule we-organic akhiwa kakhulu ngamabhondi wekhabhoni ne-hydrogen ngensimbi, njenge-lead, ne-halogen, njenge-chlorine, kukristalu omise okwe-lattice
Zingatholwa nge- lula kalula, ngentengo ephansi nangaphandle kokukhishwa, okuholela efilimini elincanyana futhi elikhanyayo elingashintshwa lifakwe kunoma isiphi isimo, esingavumela ukukhiqizwa kwamapaneli elanga ngendlela elula, ephumelelayo nange imiphumela eguqukayo futhi kulula ukuyifaka.
Kodwa-ke, banezithiyo ezimbili: eyokuqala ukuthi kungenzeka ukuzihlanganisa nabo ukukhiqizwa ngobuningi akukaze kufakazelwe; enye, ukuthi bathambekele yehla ngokushesha okukhulu ezimeni zangempela.
Uyinki we-Photovoltaic
Ukuxazulula lezi zingqinamba zama-perovskites, iqembu elivela e-US National Renewable Energy Laboratory lisungule indlela entsha elizobhekana ngayo. Imayelana nokwenza 'inki ye-photovoltaic evumela ukuthi babe ezinqubweni zokukhiqiza ezizenzakalelayo.
Lolu phenyo luqale ngo i-pervoskite elula kakhulu eyenziwe nge-iodine, lead kanye ne-methylammonium. Ngaphansi kwezimo ezijwayelekile, le nhlanganisela izokwakha amakristalu kalula, kepha kungathatha isikhathi eside emazingeni okushisa aphakeme ukuqinisa ngokuhamba kwesikhathi, okungabambezela nokwenza inqubo yokukhiqiza ibize kakhulu. Ngakho-ke iqembu labheka lezo zimo ezizosheshisa ukwakheka kwekristalu, okubandakanya ukufaka enye ingxenye yalokho okusetshenzisiwe kufakwe ezinye izinto ezinjenge-chlorine, kanye engeza lokho abakubiza ngokuthi "i-solvent negative", okuthile okungaxazulula isixazululo ngokushesha.
