Ososayensi bayaqhubeka nokuphushaamaphaneli elangaukuze lisebenze kahle kakhudlwana, futhi kukhona irekhodi elisha okufanele libikwe: Iseli elisha lelanga lifinyelela ukusebenza kahle okungamaphesenti angama-39.5 ngaphansi kwezimo ezijwayelekile zokukhanyisa kwelanga elingu-1.
I-1-sun mark iyindlela nje emisiwe yokukala inani elingaguquki lokukhanya kwelanga, manje cishe u-40% wemisebe ungaguqulwa ube ugesi.Irekhodi langaphambilini lalolu hloboiphaneli yelangaimpahla ibisebenza kahle ngama-39.2%.
Kunezinhlobo eziningi zamaseli elanga azungezile kunalokho ongase ucabange.Uhlobo olusetshenziswa lapha amaseli elanga e-triple junction III-V tandem, avame ukuthunyelwa kumasathelayithi nemikhumbi-mkhathi, nakuba futhi enamandla amakhulu endaweni eqinile.
"Amangqamuzana amasha asebenza kahle kakhulu futhi kulula ukuwaklama, futhi angaba usizo ezinhlotsheni zezinhlelo zokusebenza ezintsha, njengezinhlelo zokusebenza ezinomkhawulo noma izicelo zesikhala esikhipha umoya omncane," kusho isazi sefiziksi u-Myles Steiner we-National Renewable Energy Laboratory..”NREL) eColorado.
Ngokuphathelene nokusebenza kahle kwamangqamuzana elanga, ingxenye ethi "triple junction" ye-equation ibalulekile.Ifindo ngalinye ligxiliswe engxenyeni ethile yobubanzi be-solar spectral, okusho ukuthi ukukhanya okuncane kulahlekile futhi akusetshenzisiwe.
Ukusebenza kahle kuthuthukiswa futhi ngokusebenzisa ubuchwepheshe obubizwa ngokuthi "i-quantum well" ubuchwepheshe. I-physics ngemuva kwabo iyinkimbinkimbi, kodwa umqondo ojwayelekile wukuthi izinto ezisetshenziswayo zikhethwe ngokucophelela futhi zalungiswa, futhi zincane ngangokunokwenzeka.Lokhu kuthinta igebe lebhande, inani elincane lamandla adingekayo ukuze kujabulise ama-electron futhi kuvumele amanje ukuthi ageleze.
Kulokhu, lezi zinhlaka ezintathu zihlanganisa i-gallium indium phosphide (GaInP), i-gallium arsenide (GaAs) enokunye ukusebenza kahle kwe-quantum eyengeziwe, kanye ne-gallium indium arsenide (GaInAs).
”Isici esiyinhloko ukuthi nakuba i-GaAs iyinto enhle kakhulu futhi ivame ukusetshenziswa kumaseli e-III-V multijunction, ayinayo i-bandgap eqondile yamaseli ahlanganayo kathathu, okusho ukuthi i-photocurrent phakathi kwamaseli amathathu Ibhalansi ayilungile, ” kusho isazi se-NREL uRyan France.
"Lapha, siguqule igebe lebhendi ngokusebenzisa imithombo ye-quantum, ngenkathi sigcina ikhwalithi yento ephathekayo, eyenza le divayisi isebenze kanye nezinye izinhlelo zokusebenza."
Okunye ukuthuthukiswa okungezwe kule seli yakamuva kufaka phakathi ukukhulisa inani lokukhanya elimuncwa ngaphandle kokulahleka kwamandla kagesi okuhambisanayo.Okunye okuningana ukulungiswa kwezobuchwepheshe kwenziwe ukuze kuncishiswe imikhawulo.
Lokhu ukusebenza kahle kakhulu kwelanga oku-1 kunanoma yikuphiiphaneli yelangaiseli ekurekhodini, nakuba siye sabona ukusebenza kahle okuphezulu okuvela emisebeni yelanga enamandla kakhulu.Yize kuzothatha isikhathi ukuthi ubuchwepheshe busuke kulebhu buyiswe emkhiqizweni wangempela, ukuthuthukiswa okungenzeka kuyajabulisa.
Amaseli aphinde aqopha ukusebenza kahle kwesikhala okungamaphesenti angu-34.2, okuyilokho okufanele akuzuze lapho esetshenziswa ku-orbit.Isisindo sawo nokumelana nezinhlayiya ezinamandla amakhulu kuwenza afanelekele lo msebenzi.
"Njengoba lawa amaseli elanga elanga angu-1 asebenza kahle kakhulu ngesikhathi sokubhala, lawa maseli nawo abeka indinganiso entsha yempumelelo efinyelelekayo yabo bonke ubuchwepheshe be-photovoltaic," abacwaningi babhala ephepheni labo elishicilelwe.
